1.2.2 Control section PCB configuration
The control section PCB uses a control module to which various PCBs are mounted horizontally onto a300 x 140mm standard size PCB as shown in Figs. C to E shown in Fig. 1.2.1 Control unit configurationdiagram.A system BUS connector that is connected to the back panel is mounted on the lower back of the controlmodule and an interface connector and LED indicator are mounted on the front. A plastic front panel ismounted over this.Fig. 1.2.2 shows the state from the front and side when the control modules front panel is removed. Fig.1.2.2 shows the CPU module, and the M-BUS PCB, P-BUS PCB are mounted on the 300 x 140mmstandard PCB (S-BUS PCB) so that the part mounting face faces the S-BUS PCB. Cassette memory canbe mounted freely onto the front surface of the S-BUS PCB and M-BUS PCB.This is possible with other control modules if the various add-on PCBs listed above are mounted. In somePCBs, this is not possible due to limits in the configuration, however, the ideology is the same.

3. Trouble Diagnosis and MeasuresIf any trouble occurs during operation, it is necessary to accurately find the cause so that appropriatemeasures can be taken. Perform the following check to find the cause.
3.1 Confirmation of State of Trouble OccurrenceConfirm "when", "what was done" and "what kind of trouble" has occurred.
(1) When did the trouble occur?The time that the trouble occurred.
(2) What was done?What mode was the NC operating in?
During automatic operation: Program No., sequence No., andprogram details of when the troubleoccurred.
During manual operation : What was the manual operation mode?What was the procedure?What were the last and next steps?
What is on the setting and display unit screen?Was data being input or output?What was the machine side state?Were tools being exchanged?Has hunting occurred in the control axis?
(3) What kind of trouble occurred?
What alarm is being displayed on the alarm diagnosis screen in the setting and display unit?Display the alarm diagnosis screen and confirm the displayed details.
What is displayed on the drive amplifiers status display?Look at the display of the drive amplifiers status and confirm the alarm details.
What is displayed for the machine sequence alarm? Is the CRT screen normal?
(4) How frequently does the trouble occur?
When did the trouble occur? How frequently? (During operation of other machines?) If the troubleoccurs infrequently, the power voltage may be incorrect, or noise may be the cause. Check thatthe power voltage is correct (does the power voltage drop instantaneously when other machinesare operated), and confirm that measures against noise have been taken.
Did the trouble occur in a specific mode? Did the trouble occur when the ceiling crane was operated? What is the frequency of occurrence in the same workpiece. Repeat the operation to see if the same trouble occurs during the same step. Confirm whether the same trouble occurs when the conditions are changed.
(Try changing the override, program contents, and operation steps, etc.) What is the ambient temperature?
(Was there a sudden change in temperature? Is the fan on the top of the control unit rotating?) Are there any defective cable contacts or defective insulation?
(Has oil or cutting fluids splattered on the cables?)

3.4 Presumed Causes for AlarmsThe presumed causes for alarm related to the hardware in the MAZATROL T PLUS Series are explainedin this section.
1. The following system alarms will immediately stop the system operation when a system error occurs.The emergency stop state will be entered, so nothing will display on the screen. All operations willbe invalidated, so turn the power OFF and ON, select the 'HARDWARE ALARM screen' of thediagnosis screens, and note down the register in which the alarm occurred. Then contact the servicecenter.

There are primary alarms (alarms which when occur, another alarm also occurs), and secondaryalarms (alarms that occur even with other cause). Here, the presumed caused of the primary alarmmust be investigated.
Example(1) If both the parity error and watch dog error occur simultaneously, investigate the parity error.(2) If battery drop and another alarm occur simultaneously, investigate the battery drop first.
- 21 -

(1) Parity error
(a) MeaningA parity bit is added to improve the reliability of the CPU card DRAM and memory card QX42DSRAM.When data is written into the above RAMs, the data is written into the parity bit memory so that thenumber of "1* bits , including the parity bit, becomes an odd number, for each byte. Then, if thememory details change for any reason, the change will be detected when the data is read out, anda parity error will occur.(The changes cannot be detected when two bits are changes simultaneously. However, theprobability that two bits will change in all addresses that the software accesses is very low.)

(4) Watch dog error
(a) MeaningA watch dog error occurs when the system is not running properly to ensure the systems safety.This error has a function to stop the system immediately.In a system that runs in real time such as the NC, a routine that is passed periodically in cyclesis established. Each time this routine is passed, a special counter (watch dog timer) is reset. If thesystem does not run properly for any reason, this routine will not be passed, so this counter willnot be reset. If a set frequency clock is attached to this counters clock terminal, this counter willoverflow. This output will apply an interrupt on the CPU, and will take appropriate measuresimmediately.
Detection positionsThe CPU card (QX141, etc.) and servo CPU cards (QX721/QX722) have watch dog errordetection circuits, and the LED will light when a watch dog error occurs.

5. Explanation of Hardware
5.1 OutlineAn outline of the MAZATROL T PLUS Series operation theory will be explained in this section.Please refer to Fig. 1.1 General configuration of system using MAZATROL T PLUS.The MAZATROL T PLUS Series is composed of the control unit that can be called the control computeras a base, and the NC operation board and servo mechanism.The control unit is composed of various control modules (integrated PCBs). The following three modulesare mainly used.The CPU module, is the data processing section that is made up of the main CPU QX141 (composed ofthe latest 32-bit CPU, memory, programmable controller, various gate arrays, and peripheral IC), SRAMmemory QX42D, main cassette memory QX81 user PLC cassette memory QX81 and axis movementcontrol section QX721/QX722.The CRTC module is the display and control section made up of the graphic control PCB QX524(including various functions other than display control) for color CRT correspondence, and graphic controlPCB QX521 for monochrome correspondence.The DIO module is the I/O interface with the machine side.The NC operation board has various display functions such as the CRT display function and the MDIsetting function. The display between the NC operation board and control unit is performed with videosignals, and the data is transferred with high speed serial transmission.The servo mechanism is composed of a full digital servo amplifier, AC servo motor and position detector.Data is transferred between the full digital servo amplifier and control unit with high speed serialtransmission.
To process the data, the CPU reads (fetches) one command at a time of the software (group ofcommands called the control program) that is read into the memory beforehand. The command isanalyzed, executed and processed.This control program is divided into several programs according to the required emergency of the dataprocessing, and is located in the ROM on the memory cassette QX81QThe program that is closely related to the hardware and which waits for controls is called the monitor.Many programs (called tasks) run under the control of the monitor, and include the following:First, the contact input on the machine side, and contact output and command pulse distribution to themachine side must be processed within a set interval. Thus, these have the highest priority. The machinecontrol program that processes these is called motion.Next, the calculation program that reads the tape command, analyzes the NC command to precalculatethe data required for the above process, and that performs interpolation is called the pre-program.The man-machine interface program that displays data on the CRT setting and display unit, andprocesses the data input with the keys is called the operator controlled program.If these programs are processed in order, the request for work with a high degree of emergency cannotbe satisfied, so each task is given an order of priority, and processes are performed according to thisorder.If, during a certain task, a request for processing a task with a higher priority is received, the currentlyexecuted task will be interrupted, and the requested task will be executed. If an even higher task isreceived, that task will be performed first, and when completed, the task interrupted last will be executed.The task interrupted first will be executed last.The operation flow of the MAZATROL T PLUS Series is as shown in Fig. 5.1.As can be seen in the flow chart, the MAZATROL T PLUS Series reads in the data on the machine sidewith the built-in CPU, and makes various judgements according to that data and performs controls.In the automatic mode, when the CYCLE START button is pressed, the machining program is read in fromthe memory. If it is a movement command, the movement data for each axis is calculated and output tothe servo amplifier.If it is machine operation data, the data will be output to the power control sequence.

These CRTs are open frame type CRTs with built-in AFC for data industries that required a highreliability and high resolution play back. These are compact and light weight, and most of the circuits areintegrated on one PCB. The reliability is high, and maintainability is easy so stable operation can beexpected over a long period.

AdjustmentThere are various positions on the CRT to be adjusted, but these have been adjusted beforeshipment, so readjustment is not required.
Precautions for use
(1) Affect of magnetic fieldsThe CRT displays data by scanning an electronic beam with a magnetic field. Therefore, externalmagnetic fields will affect the display and will cause screen distortion, screen swaying and colordistortion". Take special care to external magnetic fields.For example, if the case in which the CRT is stored is made of steel plates, etc., the case will bemagnetized if a magnetic stand, etc., is installed. Note that this will cause screen distortion. The CRTis also affected by magnetic fields from motors, transformers and magnetized workpieces.
(2) Cathode-ray tube lifeThe life of the cathode-ray tube is said to be approximately 7,000 hours.However, this is the time for the emission efficiency to drop to 70% of the initial value (this will differaccording to the tube maker), and does not mean that the tube cannot be used. The phenomenonwill be a darkening of the screen, and the CRT can be used continuously.
