1. General
This manual refers to the software version V25 for the controls CC 220/320.
The diagnostic programs D21 to D28 are options which are subject to charge.
2. Safety instructions
Diagnostic programs permit critical changes to be made in the interaction of CNC,machine and drives right up to complete deletion of the CNC memory.If they are used by insufficiently trained or untrained personnel, this may thus resultin serious damage to the machine and drives, loss of software or even injury!For this reason, diagnostic programs must be started and operated only bycorrespondingly trained expert personnel.In this context, please note our extensive range of training courses. You will findan overview of the available seminars on the inner cover of this manual. Our train-ing center will gladly provide you with further information.
In some diagnostic programs, axes have to be traversed in order to optimize CNCservo loops and drives.For this reason, make sure that no one enters the machine’s danger area dur-ing execution of such diagnostic programs.
The following symbols are used in this manual in order to point out certain thingswhich are relevant to safety:
Axis movement possible!For this reason, make sure that there are no persons or objects in the machine’sdanger area.Make sure that no collisions are possible in the axis traversing range.
Machine parameter record is modified! This is followed by a CNC restart. The modi-fied machine parameters are active after this.Is there a backup of the original machine parameters?BOSCH will not be liable for damaging resulting from incorrectly calculated, pro-grammed or optimized machine parameters or non–observance of limit data!
Active axis processor data is modified!This effects the axis response.
Data loss possible!Data in the user RAM (part programs, tables etc.) may possibly be deleted or over-written.Do you possess a backup of this data?

Notes:
‘ If the softkey RESET FUNCTION and then softkey CLEAR ALL LOGIC arepressed in group operating mode DIAGNOSTIC, it is possible to enter thesoftkey level SERVICE FUNCTION only by input of a code number as fromthis point in time.When a correct code number has been entered, the softkey level SERVICEFUNCTION is accessible without input of the code number until renewed op-eration of the softkey sequence DIAGNOSTIC, RESET FUNCTION, CLEARALL LOGIC.
‘ Some diagnostic programs create files with the group identifier ”L” or ”D” forrecording data. This reduces the memory space which is available for partprograms.
‘ Data recordings can be repeated any number of times within diagnostic pro-grams, since the previous recording is overwritten by each new recording. All other operating modes of the control can be used during recording of databy a diagnostic program.Exception: CONTROL RESET and selection of a different diagnostic pro-gram cancel the currently active diagnostic program (except for D21).

D1 Logbook
D1 – 5
4. Description of the diagnostic programs
D1 – Logbook
General
The diagnostic program D1 is used for management of one or more ”logbooks”. Alogbook is a file with the identifier ”D” which contains various data for reconstructionof operating sequences, error messages or warnings etc. This file is divided into5 ring memories which store warnings, errors, system errors, other messages andoperating steps in the order of their occurrence.
Activating/deactivating a logbook
There are two possibilities for activation of a logbook:
‘ Input of a logbook file number in machine parameter P 9914. Then ACTI-VATE the machine parameters. The logbook is automatically initialized withthe specified file number after control start–up and is active as from this pointin time. The ring memories are created with the following sizes: R1 to R4:512 bytes, R5: 0 byte.
‘ Operation of softkey INIT in diagnostic program D1.
An already active logbook can be deactivated in diagnostic program D1 by pressingsoftkey INIT, input of ”0” and acknowledgement with the ENTER key or by selectionof a different logbook (also refer to softkey LOGBOOK SELECTION). A logbookcannot be activated again once it has been deactivated. Only deactivated logbookscan be deleted.

D1 Logbook
D1 – 6
The following monitor display is shown if a logbook is already active:
INIT
Initialization of a logbook (creation of a new logbook file). When the softkey INIT is pressed, the CNC expects input of a logbook file number(value range 0.3000–999999999).Input of ”0” deactivates a currently active logbook (”active” means that recordingstake place in this logbook). A logbook cannot be activated again once it has beendeactivated. Only deactivated logbooks can be deleted.Two test points are interrogated after input of the file number. However, these areof importance only for service purposes. Skip test point input by pressing the EN-TER key twice.The system then asks for the memory size for the individual ring stores. Reserva-tion of approx. 500 bytes per ring store will already permit a sensible recording tobe made. After this, the logbook is initialized and automatically activated. Any events whichoccur are recorded from this point in time onwards.
The number of logbooks which can be created is limited by the available memoryspace. Only one logbook can be active at any time.
In order to use the file number of a deactivated logbook again for an active logbook,it is first necessary to delete the deactivated logbook in the softkey level SERVICEFUNCTION and to then create a logbook again in D1 under softkey INIT.

General
The content of the communication store from the point of view of the PLC can bedisplayed on the monitor of the CNC in hexadecimal format using the diagnosticprogram D7. D7 is offered only if word coupling exists between the CNC and PLC.
The communication store is a 128 KByte dual port RAM area on the NC–PLC–wordmodule (WK3). Both the CNC and the PLC (PC 600) have read and write accessto this area.
User interface/softkey assignments
After D7 is started, the control always displays the communication store contentfrom address C000 H to C07F H (address information as hexadecimal numbersfrom the point of view of the PLC):
128 data words (256 bytes) can be displayed on one screen page. The data is dis-played in a table form (8 columns of 16 lines each). It is possible to see the assign-

D9 – EEPROM management
General
The MEM5 memory module (or CP/MEM4 in the case of CC220) contains a 32KByte EEPROM area as standard (optionally 64 KBytes).Important data should be saved in the EEPROM since the content of the EEPROMarea is not lost – in contrast to the RAM area – after a total power failure on the MEMmodule or after forced backup loading.
The following files can be written into the EEPROM area and read out again usingthe diagnostic program D9:Part programsLSEC tablesW tablesZero offset tablesCompensation tablesMachine parameters.
For example, it is then possible to choose whether machine parameters and tablesare to be copied back from the EEPROM to the RAM when the control is put intooperation again.

After D9 has been started, the monitor displays a list of all files stored in the EE-PROM area.Each entry in the list additionally contains information as to whether a file with thesame name already exists in the RAM area (column ”IN RAM”) and whether thisfile also contains the same data (column ”EQUAL”).
This list can now be extended by new entries or be shortened by deleting entries.
The functions PROGRAM EEPROM and COPY (from EEPROM to RAM) referto the files displayed here!If it is wished to store files in addition to the files which are already contained in theEEPROM, it is not necessary for files which are already stored in the EEPROM toalso be present in the RAM for programming of the EEPROM.

D21 – Logic analyzer
General
The logic analyzer permits recording of a maximum of 16 signals of the CNC–PLCinterface.
During a recording, 500 sampling operations of all selected signals (refer to softkeyCHANNEL SELECTION) are always stored. The interval between two samplingsteps is adjustable. File D121 is used to record the data. If this file does not yet exist, the system createsit automatically before a recording (file size: approx. 2 – 2.5 KByte part programmemory). An existing file D121 is overwritten by each new recording. In addition, recorded data (including the current logic analyzer settings at the timeof recording) or arbitrary logic analyzer settings can also be stored in separate filesfor possible subsequent use (refer to softkey FILE SELECTION).

D22 – Axis oscilloscope
General
The diagnostic program allows the user to assess the dynamic response of theaxes. It is thus possible to establish sluggish movement, jamming or overshoot ofthe axes or excessively slow axis circling.
For this purpose, D22 offers the possibility of simultaneously recording axis move-ments and 2 logical signals and displaying these as diagrams on the CNC monitor.
The file D122 is used for data recording. If this file does not yet exist, the systemcreates it automatically before a recording (file size approx. 5 KByte part programmemory). An existing file D122 is overwritten by each new recording. In addition, recorded data (including the axis oscilloscope settings valid at the timeof recording) or arbitrary axis oscilloscope settings can also be stored in separatefiles for possible subsequent use (refer to softkey FILE SELECTION).
480 actual axis position values are always stored during a recording at the time in-terval defined in machine parameter P9901 (interpolation time in ms). From thesevalues, the control calculates the following:
‘ Setpoint/actual speed
‘ Setpoint/actual acceleration
‘ Setpoint speed/lag
This data can then be displayed on the monitor as diagrams.

The time axis of a diagram is divided into 20 scale divisions. Complete representa-tion of the diagram is not possible if the time axis is expanded by a factor of 10. Us-ing the softkey X–DISPLAY START, it is thus possible to specify as from which scaledivision the diagram is displayed on the monitor with an expanded time axis (inputs:0–18) (also refer to softkey EXPAND X*10). The scale division specified here ismarked on the non–expanded representation of the diagram with the character ”D”(also refer to softkey DISPLAY).
EXPAND X*10
This softkey allows the diagram to be expanded by a factor 10 in the X–axis (timeaxis). The softkey is shown inverted if axis expansion is active. It is possible toswitch back to the non–expanded diagram by pressing the softkey once more. The time axis of a diagram is subdivided into 20 scale divisions. Two scale divisionsare shown on the screen in the expanded diagram. One scale division of the timeaxis corresponds here to the time t = 2.4 x P9901.

Note:
If JOG BUTTON is selected as the trigger condition, jog mode must have been acti-vated in group operating mode MACHINE. If not, triggering is initiated by the jogbutton, but no axis movement takes place.
TRIGGERPOSITION
You define here how many actual axis position values are to be stored before thetrigger event occurs. 480 actual axis position values are always stored in total.The input must be made in the unit ”Scale divisions” (see example). The permittedvalue range for inputs lies within the limits 0.0 to 20.0. The time interval from scaledivision to scale division is calculated as follows:nt = Machine parameter P9901 * 24.
Example:
It is wished to store 252 actual axis position values before the trigger event occurs:
252 : 24 = 10.5 ! Input: 10.5
The recording thus consists of 252 values before the trigger event occurs plus 228values after this trigger event (always making up a total of 480 actual axis positionvalues).

General
The contour display permits comparison of a programmed contour with the con-tour generated by the machine tool.Evaluation is performed by means of the measuring system feedback function withthe resolution set in the machine parameters (P 9901). The actual values are re-corded exactly to 1 increment for each sampling step.
User interface/softkey assignments
If D23 is selected, the control first checks whether file D123 exists. This file is re-quired by D23 to store a recording. If D123 does not exist, it is necessary to enterthe number of desired sampling steps. Approx. 16 KByte of part program memoryis required for D123 for every 1000 sampling steps. The maximum number of sampling steps is restricted only by the available free partprogram memory. The recording duration depends on the number of defined sam-pling steps and on machine parameter P9901:
T [ms] = number of sampling steps * P9901
Example: Number of sampling steps = 2000; P9901 = 10. Duration of recording = 20 s;
required part program memory: approx. 32 KByte
Note:
D123 must be deleted if it is wished to change the number of sampling steps. Onlyafter this can the number of desired sampling steps be entered again when startingD23.

The softkeys DISPLAY X–AXIS and DISPLAY Y–AXIS are used to assign an arbi-trary machine axis (axis number) to the abscissa (DISPLAY X–AXIS) and to the or-dinate (DISPLAY Y–AXIS) of the contour diagram.
The softkeys Y–AXIS EXPANSION and X–AXIS EXPANSION should be used onlyin conjunction with D27 (circular compensation).In order to optimize parameters set with D27, it is necessary to expand the repre-sentation of one axis involved in circular interpolation more than the other (e.g. Xand Y). This makes it possible to see the contour errors at quadrant transitions ofa circle more easily.The expansion factor can be entered separately for each axis (value range: 1 –1000).
In order to avoid a situation where the contour can no longer be completely dis-played on the monitor as a result of axis expansion, reduction of the non–expandedaxis by the specified factor occurs instead of an increase in the expanded axis. Thedisplayed proportions are thus correct.
Example:
Note:
If the function EXPANSION is active for an axis, the text ”AXIS” with the corre-sponding expansion factor appears on the display under the column ”MAGNIFI.FACTOR” (refer to softkey DISPLAY) in addition to ”DISPLAY” and ”MAGNIF.”.

D24 – Axis optimization
General
The servo loops of the control must be adapted to the drives used. The diagnosticprogram D24 offers the following functions for this purpose:
‘ Definition of a step function (speed) for each applied axis.
‘ Graphic representation of the axis reaction to the step function (as speedcharacteristic) and numeric display of the determined servo loop parame-ters.
‘ Display of position, lag, offset and required lag of all axes.
‘ Modification of the active required closed–loop gain.
‘ Offset adjustment of one axis.
‘ Acceptance of the optimized closed–loop gain and offset values in the ma-chine parameters.
The axis reaction is always measured by recording of 160 actual axis position val-ues. The time between 2 sampling operations corresponds to the value entered inmachine parameter P9901. The recording time is thus 1.6 s if P9901 = 10 ms.

Offset and required lag values of all axes can be changed on this operating level.
Select the axis where you wish to change the values with the cursor keys .
OFFSET–ADJAUTO
OFFSET–ADJMANUAL
Automatic or manual offset adjustment. The lag should set itself to zero whenthe offset has been entered or automatically adjusted. The changed offset valueis transferred directly to the axis processor and is thus active. The machine param-eter record is not yet changed at this point in time. Active offset values remain activeuntil they are overwritten by other offset values or until the control is reset.
REQUIREDLAG
Input of a new required lag value. This input must be made with care in order toexclude incorrect drive response.The required lag is calculated as follows:Required lag = max. axis speed (P501)/required closed loop gain (P1001).If the required lag is changed by means of this softkey, the new value becomes ac-tive for the corresponding axis when the ENTER key is pressed. For this purpose,the CNC adapts the currently active required closed loop gain in accordance withthe above relationship (the maximum axis speed remains constant).The entered value remains active until the control is reset or until a different valueis entered. The CNC modifies machine parameter P1001 correspondingly if the required lagis changed by means of the softkey REQUIRED LAG and this value then trans-ferred to the machine parameter record (by softkey ACTIVATE). P501 remainsconstant. The new values are then active after each control run–up.

D25 – Lead screw error compensation
General
The lead screw error compensation function permits compensation of the mechan-ical inaccuracies of drive spindles or rack drives. It is possible to determine andcompensate both linearity errors as well as reversing backlash. In order to permit compensation, an error curve is recorded for each axis traversingdirection for each machine axis to be compensated. The actual axis position ismeasured exactly with an external device for this purpose. The established com-pensation data is entered in the files L101–L108 using this diagnostic program. Af-ter activation of the function (refer to the section ”General information” at the endof this chapter), the control corrects the corresponding machine positions automat-ically.
Note:
The machine parameter P1509 (reversing backlash) is no longer active if the leadscrew error compensation is active.

CC 220 / 320DiagnosisFlexible Automation
D25 Lead screw error compensation

Determination of the error curve
The position errors must be determined for both the positive and negative travers-ing directions for each desired axis.
The unit of length for position and compensation values depends on the resolutionused. Normally, the resolution is 1 lm for linear and 1/100 of a degree for circularaxes.
First subdivide the traversing range of an axis into a number of equally large sec-tions (guide value, approx. 10–20 mm). This grid defines the positions in the tra-versing range at which position compensation values may be programmed lateron (refer to the section ”General information” for maximum number of position com-pensation values).
Travel the axis to the start of the traversing range (normally position 0) after refer-ence point travel.
Now define the actual axis position using an external measuring device. The differ-ence between the actual and setpoint positions (Pact – Pset) corresponds to thecompensation value which must be specified later on for this position.
First perform this measurement in positive traversing direction for arbitrary setpointpositions located on the grid. When you reach the end of the traversing range, per-form measurement in negative traversing direction for arbitrary setpoint positionson the grid.A maximum of 4000 compensation values can be entered in the control per travers-ing direction for all axes together.
Note:
It is not necessary to measure all positions defined by the grid in one traversing di-rection. If several grid points which are not measured lie between 2 positions in atraversing direction, the compensation value of the last–measured point applies tothese grid points (also refer to the section ”General information” at the end of thischapter). In this way, it is possible to perform compensation only in specific, particu-larly critical areas of the traversing path of an axis.

Programming the compensation values
Several characters are used as well as numbers for programming a compensationfile. By means of these characters, the control recognizes the meaning of any nu-meric value which has been programmed after them.
Note:
All characters required are offered on the softkey level EDIT, but can also be en-tered on the ASCII keyboard. Exception: The character LF must be entered by wayof the softkey LF on the softkey level EDIT.
All numeric values must be programmed as integers in the unit of the positioningresolution (minimum traversable distance). The positioning resolution depends onmachine parameter P103:
Positioning resolution: (increment length)
Examples: Axis type P103 Positioning resolution
Linear 3 1 mLinear 2 10 mCircular 3 1/1000th degreeCircular 2 1/100th degree
Characters used for programming:
<LF>: (LINE FEED). Each programmed line of a compensation filemust be terminated with <LF>.
S: Step distance of the grid. The step distance must be pro-grammed in the first line of the compensation file. The reference point and all axis position values pro-grammed later on must lie on this grid. However, it is notnecessary to assign a compensation value to each gridpoint.
Examples:Linear axes:”S20000” means: compensation values may be pro-grammed every 20 mm (with 1 m positioning resolution).Circular axes: ”S1000” means: compensation values may be pro-grammed every 10 degrees (with 1/100th degree position-ing resolution).
<AXIS ADDRESS>: (e.g. ”X”, ”Y”, ”Z”). The position of the compensation valueis programmed by the axis address with subsequent nu-meric value. The compensation value itself (refer to charac-ter ”P or N”) must be programmed in the same line as theposition value.

D25 Lead screw error compensation

R: This identifies the following number as the position of thereference point. The compensation value itself (refer tocharacters ”P, N”) must be programmed in the same line asthe reference point position.
Examples:Linear axis:”R100000” means: reference point position at 100 mm(with 1 m positioning resolution).Circular axis:”R35000” means: reference point position at 350 degrees(with 1/100th degree positioning resolution).
P, N: ”P” identifies the following number as a compensation valuein positive traversing direction. ”N” identifies the followingnumber as a compensation value in negative traversing di-rection. The compensation value to be entered corre-sponds to the difference between the actually measuredposition and setpoint position in the unit of positioning reso-lution.
Examples:Setpoint position Actual position Compensation value10000 10002 210000 9998 –210000 10000 0
Programming for circular axes
Only compensation values for the position range 0° x X t 360° need be pro-grammed for circular or infinite axes.If a circular axis moves out of this range, a modulo calculation is performed withrespect to the axis position for access to the compensation values so that the com-pensation values for the position range 0° x X t 360° are active.
Examples:An initial position of 300° and an end position of 400° are defined, for example,when programming a circular axis in the part program. The compensation valuesprogrammed for the traversing range from 300° to < 360° are used for this range,while the compensation values programmed for the range 0° to 40° are used forthe traversing range from 360° to 400°.The same is true analogously, for example, for a traversing distance from +40° to–40°. The compensation values programmed for the range from < 360° to 320° areactive for the path from –0° to –40°.

Compensation values for machine positionsbetween two successive group points are calculated by the control by wayof linear interpolation.
‘ Error compensation starts to act at the first programmed position in a com-pensation file. Error compensation ends at the last programmed position in a compensa-tion file.
‘ A maximum of 4000 compensation values are possible per traversing direc-tion for all axes. The grid points which have not been ”filled out” are includedin this total.
‘ The position values for the positive traversing direction must be pro-grammed in ascending order and those for the negative traversing directionin descending order.

D26 – Remote diagnosis (information)
Fast and extensive information about failed installations is essential in order to sat-isfy the availability demands placed nowadays on modern machine concepts. Forthis purpose, BOSCH offers the user the ”remote diagnosis” option, which allowsthe service center to be informed by telephone about the type and scope of theproblems which have occurred at short notice.
For this purpose, the service or maintenance center possesses a remote diagnosiscomputer, a fully–configured CNC control equipped with special software. The op-tion ”remote diagnosis” must be applied to the machine (at the machine tool manufacturer or end customer) for the CNC to be diagnosed and RE-MOTE DIAGNOSIS (softkey) activated. D26 is activated directly by the remotediagnosis computer only for certain diagnostic functions such as local analyzer,axis oscilloscope, MSD etc. D26 automatically deactivates itself after completionof these functions.
Information is exchanged between the CNC and service center on a telephone lineusing an acoustic coupler or modem. The signalling rate can be set to 300, 1200,2400 or 4800 baud by means of machine parameter 5509.
When a connection has been established between the two controls, the servicecenter is in a position to inform itself about the following data of the connected CNC:
Error messagesAll pending error messages (from control and machine) are transmitted to the ser-vice center immediately after they occur and are displayed on the CNC.

D27 – Putting into operation for circular compensation
General
The diagnostic program acts as an aid for putting into operation the option CIRCU-LAR COMPENSATION.Other required commissioning aids: – D23 Contour display.
You will find further information on the option CIRCULAR COMPENSATION in thesection ”Circular compensation”.Please refer to the sections ”Preparations for optimization” and ”Optimizing the cir-cular compensation parameters” for preparations and procedure for optimization.
Notes:
‘ The option requires the servo loop board SERVO–i and the option CS–TABLES.
‘ Circular compensation is possible only for synchronous linear axes and issensible only in conjunction with a direct measuring system.
‘ If the option PILOT CONTROL is activated in the system, the pilot controlweighting factors (machine parameters P1016 and P1017) must have beenoptimized to minimize lag before circular compensation is activated and opti-mized.
Circular compensation
The option CIRCULAR COMPENSATION allows contour errors to be minimizedduring circular interpolation in the area of the quadrant transitions (at the reversalpoint of an axis).These contour errors occur with different degrees of severity on individual ma-chines owing to the respective mechanical design (static friction, torsion etc.).
CC 220 / 320DiagnosisFlexible Automation
D27 Putting into operationfor circular compensation
D27 – 58
In order to avoid contour errors, a compensation pulse is generated at the reversalpoint of the respective axis in addition to the setpoint input. This ensures continu-ous movement of this axis through the standstill point (breakaway from static fric-tion at the right time).
The ideal pulse height is related non–linearly to the path velocity. When the optionis put into operation, this non–linear function must first be determined and graphi-cally plotted for the reversal points of all axes involved in circular interpolation onthe basis of measurements (with D27 and D23). This function is then approximatedby a maximum of three adjacent straight lines, thus providing a maximum of fourreference points (SP1–SP4) with the parameter pairs of pulse height (PH) and pathvelocity (VB) (refer to following figure).

The W–table W999999003 is used for recording all parameters necessary for cir-cular compensation (refer to the section ”Preparations for optimization” for the W–table definition program). The content of this table is read during every controlrun–up and is then active until a renewed run–up operation.On the basis of these values, the CNC calculates the required pulse height by linearinterpolation for arbitrary speeds.The pulse height is decreased linearly down to PH = 0 for path velocities below thefirst programmed reference point (SP1) down to the speed VB = 0. The pulse heightremains constant for path velocities above the last programmed reference point(SP4).

Example: P110 N10 G0 X50 Y60 Z0N20 G17 G2 X60 Y50 R40N30 G0 X50 Y60M30
Since circular compensation is active only during circular interpolation and not atits start/end, the start and end points must not be programmed at a quadrant transi-tion in this test program.

Store the definition program on a data medium (Important: read out without DFSidentifier!).
The W–table is generated later on by reading this definition program into the con-trol.
The table contains 8 columns (axis number 1–8) of 17 lines each (circle parame-ters). The compensation time required for the respective axis will be entered laterunder address ”A”.A maximum of 4 parameter pairs (pulse height and path velocity) can be specifiedunder addresses B to I for the first reversal point (U1). The parameter pairs for thesecond reversal point (U2) should be entered in addresses J to Q. The addresses of the parameter pairs valid for a reversal point need not be com-

pletely allocated in the W–table. It is thus also permitted, for example, to specifyonly two parameter pairs.
Optimizing the circular compensation parameters
D27 allows you to preallocate corresponding compensation values for the two re-versal points of each axis.Please note that the entered values are active only if the W–table values of the cor-responding axis have been preallocated the value ”0” and are active or ifW999999003 does not exist (also refer to the section ”User interface/software as-signments” under softkey ACTIVATE).Diagnostic program D23 can be used to check the contour after execution of acircle. For this purpose, setpoint and actual contours are displayed in D23. In order to per-mit the quadrant transition to be seen more easily, the respective axis can be ex-panded on the display (for instructions on operation of D23, refer to chapter ”D23Contour display”, softkey EXPANSION.
1. Define the radius which is to be used for optimization. Define the speedrange within which optimization is to take place. 9999 mm/min. is the maxi-mum permitted path feedrate.
2. Adapt the test program P110 (feedrate, radius) and then perform programselection.
3. Select D23 and set the trigger condition (e.g. program number = 110, blocknumber = 20).
4. Start D23 recording. Start test program.
5. Check quadrant transitions with contour display.
6. Select D27. Enter the corresponding axis number and compensation values(compensation pulse 1.Q/2.Q). Then press softkey ACTIVATE.
7. Select D23. Start recording. Start test program.
8. Check the quadrant positions. Optimize the compensation values if the com-pensation is too large or too small (repeat steps 6–8).
9. Determine the optimum compensation values for various speeds by adapt-ing the test program (feedrate). Note the found compensation values in atable (feedrate value, compensation path).Plot noted values graphically for each reversal point. Perform further mea-surements if necessary at critical points.
10. Approximate measured curves by maximum of 3 straight lines (refer to sec-tion ”Circular compensation”).
11. Generate W–table and plot parameter pairs of the reference points.
12. Transfer the W–table values by pressing the softkeys RESET FUNCTIONand CLEAR ALL LOGIC in group operating mode DIAGNOSTIC.

General
The diagnostic program D28 acts as a commissioning aid for the option ”TAPPINGWITHOUT COMPENSATION CHUCK” for correct adjustment of the pilot controlweighting factors for speed and acceleration (machine parameters P7203 andP7204).
Note:
The option requires the servo loop board SERVO i.

On this softkey level, the axis to be optimized and the setpoints of the pilot controlvalues for feedrate and acceleration can be defined for an optimization step (referto the section ”Optimizing the pilot control weighting factors” for the optimizationprocedure).
In addition, it is possible to transfer the pilot control values to the machine parame-ters 7203 and 7204 after optimization by means of the softkey ACTIVATE, withoutthe option ”PILOT SPEED CONTROL” having to be activated in the system. A CNCreset automatically takes place after operation of the softkey ACTIVATE.
Caution:The values are entered only in the machine parameter record by operation of thesoftkey ACTIVATE. The file L444 is not modified.In order to keep L444 up to date, L444 must first be deleted after transfer and thenregenerated (with/without text) if necessary. Possibly save the machine parameterrecord in the EEPROM!
Note:
If it is wished to optimize several axes, it is not necessary to press the softkey ACTI-VATE after adjustment of an individual axis. First optimize all desired axes succes-sively and then press the softkey ACTIVATE.

After activation of recording (refer to softkey START RECORDING), the start ofdata recording is delayed until a specific trigger event occurs. Both operation of a jog button and the start of execution of a specific program blockcan be defined as a trigger event. The set trigger condition is identified by inversedisplay of the corresponding softkey.
STARTRECORDING
Data recording is activated after operation of this softkey. At this point in time, thepilot control values entered on softkey level AXIS DATA are valid and not the ma-chine parameter values.
Recording starts when the trigger event occurs in accordance with the set triggercondition. During recording, the text ”RUNNING” is displayed on the monitor instead of thetext ”WAITING” (under the line ”RECORDING”).480 feedrate and lag values are always recorded. The recording time is calculatedas follows: T[ms] = 480 * P9901.The generated diagram can be called by means of the softkey DISPLAY only afterthe end of recording.

Preparations for optimization
Several preparations must be made before optimization:
‘ Adaption of the PLC program
The CNC output signal 16.5 is output for the duration of tapping. Feed enableis permitted by means of this signal although no M3, M4 is output.
‘ Adjustment of machine parameters
P7201 (gear speed–dependent spindle closed–loop gain):First take over the closed–loop gain value for the spindle axis from machineparameter P7014.The closed–loop gain must be set for each gear speed so that no spindleoscillations occur at the maximum speed which is to be used for tapping.
P7202 Gear speed–dependent spindle acceleration:Take over the value from machine parameter P7015. P7203 and P7204 (axis–specific pilot control weighting factors):First leave these values unchanged. The values determined later on duringoptimization can be transferred here directly from D28 by means of the soft-key ACTIVATE.
If the option ”PILOT CONTROL” is applied, it is additionally necessary totake into account the settings of P1014 and P1015 for optimization. Both pa-rameters define the maximum possible limit values for speed and accelera-tion pilot control weighting factors.
‘ Test program generation
Example: P111 N10 G1 X0 Y0 Z0 M19 S0N20 G32 F1000 M3 S1000 Z30N30 G32 F1000 M4 S1000 Z0M30
Before the start of tapping, the position servo loop of the spindle must beclosed. This is achieved, for example, by way of the function SPINDLE ORI-ENTATION or SPINDLE STOP (M5).
If drilling is to take place several times in a hole, the spindle must be posi-tioned with M19 before G32 (e.g. subsequent cutting after tool breakage).

Optimizing the pilot control weighting factors
Aim of optimization: The lag of the drilling axis should be ”0” if possible during tap-ping. Realistic values here are a lag of less than 10 lm during constant speedphases and lag values of less than 20 lm during acceleration phases.The procedure for setting the pilot control parameters is described below.Since the magnitude of the remaining lag significantly effects the accuracyof the thread, careful adjustment of the pilot control parameters is essential.
1. Select D28.
2. Set the trigger condition (e.g. program number = 11, block number = 20).
3. Set the axis number (e.g. axis number = 3; Z–axis).
4. Start recording by means of the softkey START RECORDING then start testprogram (P111).
5. Evaluate recording. Calculate the active closed–loop gain from the recordedfeedrate and lag values.
6. Compare the active closed–loop gain (CLGact) with the value entered in ma-chine parameter P1001. Depending on the result, you can now enter therough value of the feedrate weighting factor in D28 under softkey level AXISDATA:
Result of comparison Feedrate weighting factor to be entered
CLGact ~ P1001 approx. 10000 (� 300) CLGact > P1001 significantly less than 10000 CLGact < P1001 greater than 10000
7. Start recording by means of the softkey START RECORDING. Then starttest program (P111).
8. Evaluate recording. The lag which occurred during unaccelerated travel isnow relevant (stationary lag).

Note:
It is possible to increase the resolution of the lag diagram in Y–direction by scaleswitchover on the softkey level DISPLAY SPLITTING in order to permit easy recog-nition of small lag values.

9. Increase the value of the acceleration weighting factor in D28 on the softkeylevel AXIS DATA in order to now minimize the lag during acceleration/decel-eration (recommendation: step distance 100).
10. Start recording by means of the softkey START RECORDING. Then starttest program (P111).
11. Evaluate recording. The lag which occurred during accelerated travel is now relevant.
Lag Entered acceleration weighting factor
became less increase; repeat as from step 10.changed sign reduce; repeat as from step 10.no reduction OK; continue with step 12.possible withoutsign change
Notes:
It is possible to increase the resolution of the lag diagram in Y–direction by switch-ing the scale on softkey level DISPLAY SPLITTING in order to permit easy recogni-tion of small lag values.The lag during an accelerated travel must not change.
12. Select the next axis to be optimized on softkey level AXIS DATA and adapttest program (P111). Then continue with step 4.
When the weighting factors have been set for all drilling axes, press the softkey AC-TIVATE on softkey level AXIS DATA. This transfers all optimized pilot controlweighting factors to the machine parameter record. The file L444 is not changedas a result. A CNC reset automatically takes place after this. In order to keep L444 up to date, you must first delete L444 after transfer and thenregenerate it (with/without text) again if necessary.
13. Check the optimized settings using the diagnostic program D23 CONTOURDISPLAY:The offset between spindle and drilling axis at the reversal point can be de-termined with D23. To do this, plot the spindle axis and drilling axis againsteach other (by means of the softkeys DISPLAY X/Y AXIS on the softkey levelSTARTING VALUES). In the ideal case, the ”ACTUAL CONTOUR” pro-duces a straight line for drilling in and out.
