4 Faults and alarms
4.2 List of faults and alarms
Fault value (r0949, interpret bitwise binary):
Bit 0: Phase U.
Bit 1: Phase V.
Bit 2: Phase W.
Bit 3: Overcurrent in the DC link.
Note:
Fault value = 0 means that the phase with overcurrent is not recognized.
Remedy:
- check the motor data - if required, carry out commissioning.
- check the motor circuit configuration (star/delta).
- U/f operation: Increase up ramp.
- U/f operation: Check assignment of rated currents of motor and power unit.
- check the line supply quality.
- reduce motor load.
- correct connection of line reactor.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
- replace power unit.
- check the line supply phases.
F30002
Power unit: DC link voltage overvoltage
Message class:
DC link overvoltage (4)
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power unit has detected an overvoltage condition in the DC link.
- motor regenerates too much energy.
- line supply voltage too high.
- line phase interrupted.
- DC link voltage control switched off.
- dynamic response of DC link voltage controller excessive or insufficient.
Fault value (r0949, interpret decimal):
DC link voltage at the time of trip [0.1 V].
Remedy:
-increase the ramp-down time (p1121).
- set the rounding times (p1130, p1136). This is particularly recommended in U/f operation to relieve the DC link
voltage controller with rapid ramp-down times of the ramp-function generator.
- Activate the DC link voltage controller (p1240, p1280).
- adapt the dynamic response of the DC link voltage controller (p1243, p1247, p1283, p1287).
- check the line supply and DC link voltage. set p0210 as low as possible (also see A07401, p1294 = 0).
- check and correct the phase assignment at the power unit.
- check the line supply phases.

F30003
Power unit: DC link voltage undervoltage
Message class:
Infeed faulted (13)
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power unit has detected an undervoltage condition in the DC link.
- line supply failure
- line supply voltage below the permissible value.
- line phase interrupted.
Note:
The monitoring threshold for the DC link undervoltage is the minimum of the following values:
- for a calculation, refer to p0210.
