F31502 (N, A)
Encoder 1: Encoder with measuring gearbox, without valid signals
Drive object:
SERVO, VECTOR
Reaction:
OFF1 (OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The encoder with measuring gearbox no longer provides any valid signals.
Remedy:
It must be ensured that all of the encoders, with mounted measuring gearbox, provide valid actual values in opera-
tion.
Reaction upon N:

F31503 (N, A)
Encoder 1: Position tracking cannot be reset
Drive object:
SERVO, VECTOR
Reaction:
OFF1 (NONE, OFF2, OFF3)
Acknowledge:
IMMEDIATELY
Cause:
The position tracking for the measuring gearbox cannot be reset.
Remedy:
The fault should be resolved as follows:
- select encoder commissioning (p0010 = 4).
- reset the position tracking as follows (p0411.2 = 1).
- de-select encoder commissioning (p0010 = 0).
The fault should then be acknowledged and the absolute encoder adjusted.

N31800 (F)
Encoder 1: Group signal
Drive object:
All objects
Reaction:
A_INFEED: OFF2 (NONE)
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge:
NONE
Cause:
The motor encoder has detected at least one fault.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy:
Evaluates other actual messages.
Reaction upon F:
A_INFEED: OFF2 (NONE)
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowl. upon F:
IMMEDIATELY
F31801 (N, A)
Encoder 1 DRIVE-CLiQ: Sign-of-life missing
Drive object:
All objects
Reaction:
A_INFEED: OFF2 (NONE)
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge:
IMMEDIATELY
Cause:
DRIVE-CLiQ communications error between the Control Unit and the encoder involved.
Fault value (r0949, interpret hexadecimal):
0A: The sign-of-life bit in the receive telegram is not set.
