4 Faults and alarms
4.2 List of faults and alarms
F31163 (N, A)
Encoder 1: Analog sensor position value exceeds limit value
Message value:
%1
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
B_INF, ENC, VECTOR_G
Reaction:
Vector: ENCODER (IASC/DCBRK, NONE)
Infeed: ENCODER (NONE)
Acknowledge:
PULSE INHIBIT
Cause:
The position value has exceeded the permissible range of -0.5 ... +0.5.
Fault value (r0949, interpret decimal):
1: Position value from the LVDT sensor.
2: Position value from the encoder characteristic.
Remedy:
For fault value = 1:
- Check the LVDT ratio (p4678).
- check the reference signal connection at track B.
For fault value = 2:
- check the coefficients of the characteristic (p4663 ... p4666).
Reaction upon N:

A31400 (F, N)
Encoder 1: Alarm threshold zero mark distance error
Message value:
%1
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
B_INF, ENC, VECTOR_G
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.
Remedy:
- check that the encoder cables are routed in compliance with EMC.
- check the plug connections.
- check the encoder type (encoder with equidistant zero marks).
- adapt the parameter for the distance between zero marks (p0424, p0425).
- replace the encoder or encoder cable.
Reaction upon F:
Vector: NONE (ENCODER, IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowl. upon F:
IMMEDIATELY
Reaction upon N:
NONE
Acknowl. upon N:
NONE
A31401 (F, N)
Encoder 1: Alarm threshold zero mark failed
Message value:
%1
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
B_INF, ENC, VECTOR_G
Reaction:
NONE
Acknowledge:
NONE
Cause:
The 1.5 x parameterized zero mark distance was exceeded.
The zero mark distance for the zero mark monitoring is set in p0425 (rotary encoder) or p0424 (linear encoder).
