F31503 (N, A) Encoder 1: Position tracking cannot be reset
Message value: -
Message class: Actual position/speed value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Component: None
Reaction: Vector: OFF1 (NONE, OFF2, OFF3)
Infeed: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: The position tracking for the measuring gear 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).
- deselect encoder commissioning (p0010 = 0).
The fault should then be acknowledged and the absolute encoder adjusted.
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
A31700 Encoder 1: Effectivity test does not supply the expected value
Message value: Fault cause: %1 bin
Message class: Safety monitoring channel has identified an error (10)
Drive object: B_INF, ENC, VECTOR_G
Component: Sensor Module Encoder 1
Reaction: NONE
Acknowledge: NONE
Cause: The DRIVE-CLiQ encoder fault word supplies fault bits that have been set.
Alarm value (r2124, interpret binary):
Bit x = 1: Effectivity test x unsuccessful.
Remedy: Replace encoder.
N31800 (F) Encoder 1: Group signal
Message value: -
Message class: Actual position/speed value incorrect or not available (11)
Drive object: B_INF, ENC, VECTOR_G
Component: None
Reaction: Vector: ENCODER (IASC/DCBRK, NONE)
Infeed: OFF2 (NONE)
Acknowledge: NONE
Cause: The motor encoder has detected at least one fault.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: Evaluate the other messages that are presently available.
Reaction upon F: Vector: ENCODER (IASC/DCBRK, NONE)
Infeed: OFF2 (NONE)
Acknowl. upon F: IMMEDIATELY
