Safety and operating instructions for drive converters
Safety and operating instructions
for drive converters(in conformity with the low-voltage directive 73/23/EEC)
1. General
In operation, drive converters, depending on their degree of protection, may have live, uninsulated, andpossibly also moving or rotating parts, as well as hot surfaces.
In case of inadmissible removal of the required covers, of improper use, wrong installation or maloperation,there is the danger of serious personal injury and damage to property.
For further information, see documentation.
All operations serving transport, installation and commissioning as well as maintenance are to be carried outby skilled technical personnel(Observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 and IEC 664 orDIN/VDE 0110 and national accident prevention rules!).
For the purposes of these basic safety instructions, "skilled technical personnel" means persons who arefamiliar with the installation, mounting, commissioning and operation of the product and have thequalifications needed for the performance of their functions.
2. Intended use
Drive converters are components designed for inclusion in electrical installations or machinery.
In case of installation in machinery, commissioning of the drive converter (i.e. the starting of normal operation)is prohibited until the machinery has been proved to conform to the provisions of the directive 89/392/EEC(Machinery Safety Directive - MSD). Account is to be taken of EN 60204.
Commissioning (i.e. the starting of normal opertion) is admissible only where conformity with the EMCdirective (89/336/EEC) has been established.
The drive converters meet the requirements of the low-voltage directive 73/23/EEC. They are subject to theharmonized standards of the series prEN 50178/DIN VDE 0160 in conjunction with EN 60439-1/ VDE 0660,part 500, and EN 60146/ VDE 0558.

1 Maintenance
WARNING
Voltages exceeding 1000 V are used in the operation of this equipment and can cause loss
of life or severe personal injury.The converter voltage does not drop to a harmless level (< 60 V) for at least 2 minutesafter disconnection from the supply. Extreme care must be taken when working on theequipment. The equipment must be installed in accordance with the applicable NationalElectrical Code (VBG 4 in Federal Republic of Germany) and any other state or localcodes. It is essential to follow the safety instructions listed below:
Only qualified maintenance personnel may text and repair this equipment and partsthereof.
During normal operation, keep all covers in place and cabinet doors shut.
If the discharge resistors in the commutating capacitors have failed, dangerously highvoltages are present in the unit for a long period of time. Before touching any electrical
contacts, check to ensure that the voltage between two thyristor-anode terminals in themachine-end converter is less than 60 V. Failure to observe this warning may result ingrievous or even fatal injury.
If a short-circuit has occurred in the unit, all screw-type connections and busbars mustbe checked before the unit is switched on again.
When it is necessary to take measurements with the power turned on, do not touch anyelectrical connection points. Keep one hand completely clear of the electrical circuitry allthe time.
Do not use any measuring equipment if you know that it is damaged or detective.
When servicing the unit with the power on, stand on some type of insulation (anti-static)
and ensure that this is not grounded. When working on a machine connected to the supply or on the supply line to the
machine, the main switch on the equipment or the relevant circuit-breaker in thedistribution board for the plant must be locked in the OFF position by means of apadlock.
When performing maintenance work and routine checks for visible defects, make surethat all power supplies for the equipment are switched off and that the incoming circuit-breaker in the plant is locked in the OFF position.
Use only authorized spare parts in the repair on the equipment.

Edition 05.97 1 Maintenance
Siemens AG 6SC2487-6AK00 11SIMOVERT A Maintenance Instructions
Achievement of a long service life was a basic criterion in design and production of SIMOVERT A converters.These contain a limit number of parts subject to wear (e.g. fans) and these like other essential spare partsare arranged so that they are exchangeable. Exchange of these parts is described in Sections 5 through 7 ofthese instructions.A description of the alarms and warning messages of the converter is to be found in Sections 2 through 4.These are in the form of plain text messages to facilitate rapid fault diagnostics and fault clearance. Themajor causes of a fault and possible countermeasures are given in the individual diagnostic messages.
The fan bearings are designed for the following service periods:
For converters of construction type B: 25,000 hrs type D: 25,000 hrs
type C: 20,000 hrs type E: 20,000 hrs
The fans must be replaced at the prescribed intervals to guarantee continuous availability of the converter.
Dust deposits inside the converter should be carefully removed at regular intervals (at least once a year) byqualified personnel. The unit must be cleaned with a brush and vacuum cleaner, or with dry compressed air(max. 1 bar) in inaccessible parts.
The converters are designed for a defined short-circuit current on the input side (see Chapter 3 "TechnicalData" in Description 6SC2487-6AG00); the prescribed fuses (see Commissioning Instructions "Start-up,Programs", Order No.: 6SC2487-6AH00) are capable of disconnecting this current to prevent any damage tothe converter.Short circuits occurring inside the converter and at the motor end cause internal protective devices torespond.
In cabinet units with the M11 option (dust protection), the state of the filter mats must be checked regularly(once a month at the beginning) to ascertain how quickly they become clogged. The mats must then bereplaced at appropriate intervals.

NOTE
When modules in the subrack are replaced (refer to Section 5), make sure that the ICSA and DLCA moduleshave the same software version (refer to Section 6).
In the event of a fault, the converter is switched off through blocking of the inverter and opening of the maincontactor (plant-side contactor in construction types C and E). The occurrence of an alarm does not result in the
converter being switched off.
When a group fault or alarm message occurs, the display automatically switches over to the group fault or alarm
signal with the highest priority. In the event of a group fault message, the red FAILURE (fault) lamp lights up in
addition (FAILURE flashes when an alarm message is output).
Resetting of the display can be deferred for approximately one minute by pressing F2
key to allow adjustment
of a parameter prior to resetting.
If LOCAL is selected in S11:P911, the fault can be reset with the R key.
If several faults occur simultaneously, the messages can be called one after the other (scrolled) by pressing
the + F1 key.

Example:
2.1 Direct access to diagnostic messages
The fault messages that are displayed are group fault messages (e.g. MALFUNCTION ICUA); diagnostic
messages referring to these can then also be accessed (e.g. ANALOG INPUT INT). The diagnostic messages
can be accessed by way of program S44 Diagnostic/Memory (see Section 3 for program description).
It is also possible to call up the diagnostic messages directly with the aid of the key. However, this will only
work if the operating program is not waiting for an input to be completed that has been started. If this is the
case, pressing the key results in display of the group fault message being deferred and reappearance of
the interrupted input function.

288 PT FAULT***
ThePTissignalling afault.
The meaning of the fault
depends on the PT
configuration. The fault
signalled by the PT is
displayed as a number
after the text "PT FAULT".
This number must not be
confused with the internal
converter fault number
(288). The PT fault
number is not displayed in
the diagnostic memory
(after the fault has been
reset).
The PT can signal up to
three faults at a time;
these correspond to
diagnostic messages 288
to 290 in the converter.
The faults must be sought and rectified within the
SIMADYN D configuration

296 dn/dt > VALID
The speed sensor checks
the speed variation
between two consecutive
sampling intervals (4 ms).
If the speed has changed
by more than the valueset in S43:P505 and
causes an overcurrent or
overvoltage, this
diagnostic message
appears. It indicates that
the fault has been caused
by an excessive change
in speed.
If the speed changes by
more than double the
value set in S43:P505
within one sampling
interval, the converter
switches to the "faulted"state after 20 ms.
If the speed ripple is being
caused solely by load
changes, the fault can be
eliminated by increasing
S43:P505 accordingly.
