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.
