F05050
Parallel circuit: Pulse enable in spite of pulse inhibit
Message value:
%1
Message class:
Application/technological function faulted (17)
Drive object:
B_INF, VECTOR_G
Component:
Power Module
Reaction:
Vector: OFF2 (NONE, OFF1, OFF3, STOP2)
Infeed: OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
A power unit signals that the pulses are enabled although the pulses are inhibited.
Fault value (r0949, interpret decimal):
Number of the power unit involved.
Remedy:
The power unit is defective and must be replaced.
F05051
Parallel circuit: Power unit pulse enable missing
Message value:
%1
Message class:
Application/technological function faulted (17)
Drive object:
B_INF, VECTOR_G
Component:
Power Module
Reaction:
Vector: OFF2 (NONE, OFF1, OFF3, STOP2)
Infeed: OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
For one or several power units, the pulses were not able to be enabled.
Fault value (r0949, interpret decimal):
Number of the power unit involved.
Remedy:
- acknowledge power unit faults that are still present.
- inhibit the pulses of the power unit involved (p7001).
A05052 (F)
Parallel circuit: Illegal current asymmetry
Message value:
%1
Message class:
Application/technological function faulted (17)
Drive object:
B_INF, VECTOR_G
Component:
Power Module
Reaction:
NONE
Acknowledge:
NONE
Cause:
The deviation of the individual currents of the power units exceeds the alarm threshold specified in p7010.
Alarm value (r2124, interpret decimal):
1: Phase U.
2: Phase V.
3: Phase W.
Remedy:
- inhibit the pulses of the faulted power unit (p7001).
- check the connecting cables. Loose contacts can cause current spikes.
- the motor reactors are non-symmetrical or faulty and must be replaced.
- the CTs must be calibrated or replaced.
Reaction upon F:
Vector: NONE (OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowl. upon F:
IMMEDIATELY
