4 Faults and alarms
4.2 List of faults and alarms
Note:
This fault is also indicated via binector input r53030.0.
See also: p50700 (CUD analog input 0 type)
Remedy: - Check the wiring of the input terminals (X177.25/26) (cable break, contacts, etc).
- Check the parameter assignment for the "Main setpoint" analog input (p50700).

F60047 (N, A) Wire break at analog input 1
Message value: -
Message class: General drive fault (19)
Drive object: DC_CTRL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: A wire break has been detected at the CUD's analog input 1 (X177.27/28).
This fault is triggered if p50700 = 2 (unipolar monitoring of current input (+4 mA to +20 mA)) is set and an input
current of less than 2 mA is flowing.
Possible fault causes:
- Wire break or contact problem on supply line
- Parameter p50710 set incorrectly
Note:
This fault is also indicated via binector output r53030.1.
See also: p50710 (CUD analog input 1 type)
Remedy: - Check the wiring of the input terminals (X177.27/28) (cable break, contacts, etc).
- Check the parameter assignment for analog input 1 (p50710).
Reaction upon N: NONE

F60050 (N, A) Optimization run aborted due to internal cause
Message value: %1
Message class: Hardware/software error (1)
Drive object: DC_CTRL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: An optimization run which had been started has been interrupted due to an internal cause.
Fault value (r0949, interpret decimal):
General, not assigned to a specific optimization run:
100: Internal software error
Field current controller optimization run:
101: Alpha G limit reached when determining the Rf
102: Field current oscillation > 20 % when determining the Rf
103: Calculated field circuit resistance too high (> 4000 ohms)
104: Unable to ascertain field circuit inductance
105: Calculated field circuit inductance too high (> 1000 H)
106: Field current > 100% at start of optimization
107: Rf determination failed (Rf <= 0)
108: Internal software error
Armature current controller optimization run:
201: Alpha G limit reached when determining the Ra
202: Armature current oscillation > 20 % when determining the Ra
203: Calculated armature circuit resistance too high (> 4000 ohms)
