12.3 Faults and alarms
F30015
Power unit: Phase failure motor cable
Message class:
Application/technological function faulted (17)
Message value:
-
Component:
Motor
Response:
OFF2
Acknowledgment: IMMEDIATELY
Cause:
A phase failure in the motor feeder cable was detected.
The signal can also be output in the following case:
- The motor is correctly connected, however the closed-speed control is instable and therefore an oscillating torque is
generated.
Note:
Chassis power units do not feature phase failure monitoring.
Remedy:
- Check the motor feeder cables.
- Check the speed controller settings.
A30016
Power unit: Load supply switched off
Message class:
Network fault (2)
Message value:
%1
Component:
Power Unit
Response:
NONE
Acknowledgment: NONE
Cause:
The DC link voltage is too low.
Alarm value (r2124, interpret decimal):
DC link voltage at the time of the trip [V].
Remedy:
- Switch on load supply.
- Check the line supply if necessary.
F30017
Power unit: Hardware current limit has responded too often
Message class:
Power electronics faulted (5)
Message value:
Fault cause: %1 bin
Component:
Power Unit
Response:
OFF2
Acknowledgment: IMMEDIATELY
Cause:
The hardware current limitation in the relevant phase (see A30031, A30032, A30033) has responded too often. The
number of times the limit has been exceeded depends on the design and type of power unit.
- Closed-loop control is incorrectly parameterized.
- Fault in the motor or in the power cables.
- The power cables exceed the maximum permissible length.
- Motor load too high
- Power unit defective.
Fault value (r0949, interpret binary):
Bit 0: Phase U
Bit 1: Phase V
Bit 2: Phase W
Additional bits:
Only for internal Siemens troubleshooting.
Note:
Fault value = 0 means that the phase with current limiting is not recognized (e.g. for blocksize device).
