4.2 List of faults and alarms
Remedy: Check the threshold for monitoring the minimum line frequency (p50363).

Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F60009 (N, A) Line frequency greater than maximum line frequency
Message value: %1
Message class: Network fault (2)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: The line frequency has overshot the set threshold for monitoring of the maximum line frequency for more than 40 ms.
Fault value (r0949, interpret decimal):
1: Armature supply frequency greater than maximum line frequency
2: Field supply frequency greater than maximum line frequency
Note:
r50047[1]: Incorrect frequency value in Hz
Remedy: Check the threshold for monitoring the maximum line frequency (p50364).

F60010 (N, A) Armature circuit uneven current distribution
Message value: %1
Message class: Ground fault / inter-phase short-circuit detected (7)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: An uneven current distribution through the thyristors has been identified in the armature circuit.
Significantly less current flows in one thyristor than in the others.
Remarks:
- This monitoring is only effective if the average current value across all thyristors is greater than 20 % of r50072[1].
- The current in a thyristor is significantly lower, if, for a period of one second, the average value is less than 35 % of
the average value across all thyristors.
Possible causes:
- A fuse has blown.
- A thyristor is not fired (defective thyristor, defective pulse transformer, defective firing electronics).
Fault value (r0949, interpret decimal):
Number of the thyristor that is conducting the significantly lower current.
Note:
r50047[1]: Average current value through all armature thyristors.
r50047[2]: Average current value through the thyristor with the excessively low current, in torque direction I.
r50047[3]: Average current value through the thyristor with the excessively low current, in torque direction II.
The current values as a % are referred to r50072[1].
Note:
Even though the response to this fault message is set to "NO" when using p2100/p2101, or the message type set to
"Alarm" or "No message" when using p2118/p2119, in the case of a fault, the drive still exits the OPERATION (RUN)
state and goes into state o4.1 (wait for the fuse monitoring OK message.)
Remedy: - Check the fuses in the power unit.
- If required, perform a thyristor diagnostics routine (p50830).
