SINAMICS S110 List Manual (LH7), 06/2012, 6SL3097-4AP10-0BP3
Remedy:
- Check the clamped tool.
- Check the tolerance and if required, adapt (p5040).
- Check the thresholds and if required, adapt (p5041).
- Check analog sensor S1 and connections.

NONE (ENCODER, IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F:
IMMEDIATELY

A31999 (F, N)
Encoder 1: Unknown alarm
Message value:
New message: %1
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
NONE
Acknowledge:
NONE
Cause:
A alarm has occurred on the Sensor Module for encoder 1 that cannot be interpreted by the Control Unit firmware.
This can occur if the firmware on this component is more recent than the firmware on the Control Unit.
Alarm value (r2124, interpret decimal):
Alarm number.
Note:
If required, the significance of this new alarm can be read about in a more recent description of the Control Unit.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy:
- replace the firmware on the Sensor Module by an older firmware version (r0148).
- upgrade the firmware on the Control Unit (r0018).
Reaction upon F:
NONE (ENCODER, IASC/DCBRAKE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowl. upon F:
IMMEDIATELY (POWER ON)
Reaction upon N:
NONE
Acknowl. upon N:
NONE
F32100 (N, A)
Encoder 2: Zero mark distance error
Message value:
%1
Drive object:
SERVO_S110-CAN, SERVO_S110-DP, SERVO_S110-PN
Reaction:
OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2)
Acknowledge:
PULSE INHIBIT
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).
Fault value (r0949, decimal interpretation):
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).
- if message output above speed threshold, reduce filter time if necessary (p0438).
- replace the encoder or encoder cable
