F31131 (N, A)
Encoder 1: Deviation, position incremental/absolute too large
Drive object:
All objects
Reaction:
A_INFEED: NONE
SERVO: ENCODER (IASC / DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: 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.
Fault value (r0949, interpret decimal):
Deviation in quadrants (1 pulse = 4 quadrants).
Incremental encoder: When the zero pulse is passed, a deviation in the incremental position was detected.

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.

F31150 (N, A)
Encoder 1: Initialization error
Drive object:
All objects
Reaction:
A_INFEED: NONE
SERVO: ENCODER (IASC / DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
VECTOR: ENCODER (IASC / DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge:
PULSE INHIBIT
Cause:
Encoder functionality selected in p0404 is not operating correctly.
Fault value (r0949, interpret 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 track C/D).
See also: p0404 (Encoder configuration effective), p0491 (Motor encoder fault response ENCODER)
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.
Reaction upon N:

A31400 (F, N)
Encoder 1: Alarm threshold zero mark distance error
Drive object:
All objects
Reaction:
NONE
Acknowledge:
NONE
Cause:
The measured zero mark distance does not correspond to the parameterized zero mark distance.
For distance-coded encoders, the zero mark distance is determined from zero marks detected pairs. This means that
if a zero mark is missing, depending on the pair generation, this cannot result in a fault and also has no effect in the
system.
The zero mark distance for the zero mark monitoring is set in p0425 (rotary encoder) or p0424 (linear encoder).
Alarm value (r2124, interpret decimal):
Last measured zero mark distance in increments (4 increments = 1 encoder pulse).
The sign designates the direction of motion when detecting the zero mark distance.
