13.2 Alarms
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).

A001
Calculating time
The calculating time utilization of the CUVC
board is too high
- Observe r829 CalcTimeHdroom
- Increase P357 Sampling Time or
- Reduce P340 Pulse Frequency
A002
SIMOLINK start alarm
Start of the SIMOLINK ring is not functioning.
- 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
A014
Simulation active alarm
The DC link voltage is not equal to 0 when the
simulation mode is selected (P372 = 1).
- Set P372 to 0.
- Reduce DC link voltage (disconnect the
converter from the supply)
A015
External alarm 1
Parameterizable external alarm input 1 has
been activated.
Check
- whether the cable to the corresponding
digital input has been interrupted.
- parameter P588 Src No Ext Warn1
A016
External alarm 2
Parameterizable external alarm input 2 has
been activated.
Check
- whether the cable to the corresponding
digital input has been interrupted.
- parameter P589 Src No Ext Warn2
A017

alarm
active
The switch for blocking the inverter pulses (X9
terminal 5-6) has been opened (only for units
with Order No. ...-11, ...-21, ...-31, ...-61)
Close switch X9 5-6 and thus release the
inverter pulses.
A020
Overcurrent
An overcurrent condition has occurred.
Check the driven load for an overload
condition.
- Are the motor and the converter matched?
- Have the dynamic performance requirements
been exceeded.
A021
Overvoltage
An overvoltage condition has occurred.
Check the supply voltage. The converter
regenerates without regeneration possibility.
