Faults and Alarms
List of faults and alarms
Cause:
Hardware current limit for phase U responded. The pulsing in this phase is inhibited for one pulse period.
- 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 module defective.
Remedy:
- check the motor data.
- check the motor circuit configuration (star-delta).
- check the motor load.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
A30032
Power module: Hardware current limiting, phase V
Reaction:
NONE
Acknowledge:
NONE
Cause:
Hardware current limit for phase V responded. The pulsing in this phase is inhibited for one pulse period.
- 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 module defective.
Remedy:
- check the motor data.
- check the motor circuit configuration (star-delta).
- check the motor load.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
A30033
Power module: Hardware current limiting, phase W
Reaction:
NONE
Acknowledge:
NONE
Cause:
Hardware current limit for phase W responded. The pulsing in this phase is inhibited for one pulse period.
- 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 module defective.
Remedy:
- check the motor data.
- check the motor circuit configuration (star-delta).
- check the motor load.
- check the power cable connections.
- check the power cables for short-circuit or ground fault.
- check the length of the power cables.
F30035
Power module: Overtemp. air intake
Reaction:
OFF1 (OFF2)
Acknowledge:
IMMEDIATELY
Cause:
Power module air intake temperature has exceeded the permissible limit value.
- ambient temperature too high.
- insufficient cooling, fan failure
Fault value (r0949):
Temperature [1 bit = 0.01 °C].
Remedy:
- check whether the fan is running.
- check the fan elements
- check whether the ambient temperature is in the permissible range.
Notice:
This fault can only be acknowledged after this alarm threshold for alarm A05002 has been fallen below.
