Alarms

Number / Alarm Cause
A001 The calculating time utilization is too high
Calculating time a) At least 3 failures of time slots T6 or T7 (see
also parameter r829.6 or r829.6)
b) At least 3 failures of time slots T2, T3, T4 or
T5 (see also parameter r829.2 to r829.5)
A002 Start of the SIMOLINK ring is not functioning.
SIMOLINK start alarm
A014 The DC link voltage is not equal to 0 when the
simulation mode is selected (P372 = 1).
Simulation active alarm
A015 Parameterizable external alarm input 1 has
been activated.

A016 Parameterizable external alarm input 2 has
been activated.
External alarm 2
A017 The switch for blocking the inverter pulses (X9
terminal 5-6) has been opened (only for units
Safe Stop alarm active with Order No. ...-11, ...-21, ...-31, ...61)
A020 An overcurrent condition has occurred.

The alarm message is periodically displayed on the PMU by A = alarm/
alarm message and a 3-digit number. An alarm cannot be
acknowledged. It is automatically deleted once the cause has been
eliminated. Several alarms can be present. The alarms are then
displayed one after the other.
When the converter is operated with the OP1S operator control panel,
the alarm is indicated in the lowest operating display line. The red LED
additionally flashes (refer to the OP1S operating instructions).
Counter-measure
- Observe r829 CalcTimeHdroom
- Increase P357 Sampling Time or
- Reduce P340 Pulse Frequency
- Check the fiber-optic cable ring for
interruptions
- Check whether there is an SLB without
voltage in the ring
- Check whether there is a faulty SLB in the
ring
- Set P372 to 0.
- Reduce DC link voltage (disconnect the
converter from the supply)
Check
- whether the cable to the corresponding
digital input has been interrupted.
- parameter P588 Src No Ext Warn1
Check
- whether the cable to the corresponding
digital input has been interrupted.
- parameter P589 Src No Ext Warn2
Close switch X9 5-6 and thus release the
inverter pulses.
Check the driven load for an overload
condition.
- Are the motor and the converter matched?
- Have the dynamic performance requirements
been exceeded.
Check the supply voltage. The converter
regenerates without regeneration possibility.
