F31131 (N, A)
Encoder 1: Deviation, position incremental/absolute too large
Message value:
%1
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
ENCODER (IASC/DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge:
PULSE INHIBIT
Cause:
Absolute encoder:
When cyclically reading the absolute position, an excessively high difference 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.
Incremental encoder:
When the zero pulse is passed, a deviation in the incremental position was detected.
For equidistant zero marks, the following applies:
- The first zero mark passed supplies the reference point for all subsequent checks. The other zero marks must have
n times the distance referred to the first zero mark.
For distance-coded zero marks, the following applies:
- the first zero mark pair supplies the reference point for all subsequent checks. The other zero mark pairs must have
the expected distance to the first zero mark pair.
Fault value (r0949, decimal interpretation):
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.
- adapt the parameter for the clearance between zero marks (p0425).
- if message output above speed threshold, reduce filter time if necessary (p0438).

Encoder 1: Fault when determining the position
Message value:
Fault cause: %1 bin
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
ENCODER (IASC/DCBRAKE, NONE)
Acknowledge:
PULSE INHIBIT
Cause:
The DRIVE-CLiQ encoder supplies status information via bits in an internal status/fault word.
Some of these bits cause this fault to be triggered. Other bits are status displays. The status/fault word is displayed
in the fault value.
Fault value (r0949, interpret binary):
Bit 0: F1 (safety status display)
Bit 1: F2 (safety status display)
Bit 2: Lighting (reserved)
Bit 3: Signal amplitude (reserved)
Bit 4: Position value (reserved)
Bit 5: Overvoltage (reserved)
Bit 6: Undervoltage (reserved)
Bit 7: Overcurrent (reserved)
Bit 8: Battery (reserved)
Bit 16: Lighting (--> F3x135, x = 1, 2, 3)
Bit 17: Signal amplitude (--> F3x135, x = 1, 2, 3)
Bit 18: Singleturn position 1 (--> F3x135, x = 1, 2, 3)
Bit 19: Overvoltage (--> F3x135, x = 1, 2, 3)
Bit 20: Undervoltage (--> F3x135, x = 1, 2, 3)
Bit 21: Overcurrent (--> F3x135, x = 1, 2, 3)
Bit 22: Temperature exceeded (--> F3x405, x = 1, 2, 3)
Bit 23: Singleturn position 2 (safety status display)
