231502 <location>Encoder 1: Encoder with measuring gear, without valid signals
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF1 (OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The encoder with measuring gear no longer provides any valid signals.
Remedy: It must be ensured that all of the encoders, with mounted measuring gear, provide valid actual values in operation.
231503 <location>Encoder 1: Position tracking cannot be reset
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The position tracking for the measuring gear cannot be reset.
Remedy: The fault should be resolved as follows:
- select encoder commissioning (p0010 = 4).
- reset the position tracking as follows (p0411.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and the absolute encoder adjusted.
231700 <location>Encoder 1: Effectivity test does not supply the expected value
Message value: Fault cause: %1 bin
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: The DRIVE-CLiQ encoder fault word supplies fault bits that have been set.
Fault value (r0949, interpret binary):
Bit x = 1: Effectivity test x unsuccessful.
Remedy:
231800 <location>Encoder 1: Group signal
Message value: -
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: ENCODER (IASC/DCBRAKE, NONE)
Acknowledge: NONE
Cause: The motor encoder has detected at least one fault.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: Evaluates other actual messages.
