F32131 Encoder 2: Deviation, position incremental/absolute too large
Reaction: NONE (DCBRAKE, ENCODER, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: When cyclically reading the absolute position, an excessively high deviation to the incremental position was
detected. The absolute position that was read is rejected.
Limit value for the deviation:
- EnDat encoder: Is supplied from the encoder and is a minimum of 2 quadrants (e.g. EQI 1325 = 2 quadrants, EQN
1325 = 50 quadrants).
- other encoders: 15 pulses = 60 quadrants.
Fault value (r0949, decimal):
Deviation in quadrants (1 pulse = 4 quadrants).
Remedy: - check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- replace the encoder or encoder cable.
- check whether the coding disk is dirty or there are strong ambient magnetic fields.
F32150 Encoder 2: Initialization error
Reaction: NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (power on)
Cause: Encoder functionality selected in p0404 is not operating correctly.
Fault value (r0949, hexadecimal):
The fault value is a bit field. Every set bit indicates functionality that is faulted.
The bit assignment corresponds to that of p0404 (e.g. bit 5 set: Error C/D track).
Remedy: - Check that p0404 is correctly set.
- check the encoder type used (incremental/absolute value) and for SMCxx, the encoder cable.
- if relevant, note additional fault/error messages that describe the fault in detail.
A32405 (F, N) Encoder 2: Encoder evaluation temperature too high
Reaction: NONE
Acknowledge: NONE
Cause: The encoder evaluation for a motor with DRIVE-CLiQ has detected an excessively high temperature.
The fault threshold is 125 ° C.
Alarm value (r2124, decimal):
Measured board/module temperature in 0.1 °C.
Remedy: Reduce the ambient temperature for the DRIVE-CLiQ connection of the motor.
Reaction upon F: NONE (DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge IMMEDIATELY
upon F:
Reaction upon N: NONE
Acknowledge NONE
upon N:
A32410 (F, N) Encoder 2: Serial communications
Reaction: NONE
Acknowledge: NONE
Cause: Serial communication protocol transfer error between the encoder and evaluation module SMCxx.
Alarm value (r2124, binary):
Bit 0: Alarm bit in the position protocol.
Bit 1: Incorrect quiescent level on the data line.
Bit 2: EnDat encoder does not response (does not supply a start bit).
Bit 3: CRC error: The checksum in the protocol from the encoder does not match the data.
Bit 4: Incorrect encoder acknowledgement: The encoder incorrectly understood the task (request) or cannot execute
it.
Bit 5: Internal error in the EnDat driver: An illegal mode command was requested.
Bit 6: Position value longer than 40 bits.
Remedy: - check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- replace the encoder.
