upon N:
A31431 (F, N)
Encoder 1: Difference, absolute/incremental position too large
Reaction:
NONE
Acknowledge:
NONE
Cause:
When cyclically reading the absolute position, an excessively high difference to the incremental position was
detected.
Alarm value (r2124, 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.
- coding disk dirty or strong magnetic fields.

Encoder 1 DRIVE-CLiQ: Sign-of-life missing
Reaction:
ENCODER (DCBRAKE, NONE)
Acknowledge:
IMMEDIATELY
Cause:
DRIVE-CLiQ communications error between the control unit and the encoder involved.
Fault value (r0949, hexadecimal):
0A: The sign-of-life bit in the receive telegram is not set.
Remedy:
- check the electrical cabinet design and cable routing for EMC compliance
- replace the component involved.

F31802
Encoder 1: Time slice overflow
Reaction:
ENCODER (DCBRAKE, NONE)
Acknowledge:
IMMEDIATELY
Cause:
Time slice overflow, encoder 1.
Fault value (r0949, decimal):
9: Time slice overflow of the fast (current controller clock cycle) time slice.
10: Time slice overflow of the average time slice.
12: Time slice overflow of the slow time slice.
999: Timeout when waiting for SYNO, e.g. unexpected return to non-cyclic operation.
Remedy:
Reduce the current controller frequency.
F31804
Encoder 1: CRC CODE RAM
Reaction:
ENCODER (DCBRAKE, NONE)
Acknowledge:
IMMEDIATELY
Cause:
The checksum via the CODE-RAM of the sensor module has changed in operation.
Fault value (r0949, hexadecimal):
Difference between the checksum at POWER ON and the actual checksum.
Remedy:
Hardware defect: Replace the sensor module.
Firmware error: If required, upgrade the firmware.
F31805
Encoder 1: Incorrect EPROM checksum
Reaction:
ENCODER (DCBRAKE, NONE)
Acknowledge:
IMMEDIATELY
