11.3 Faults and alarms
Remedy:
- Carry out a POWER ON (switch-off/switch-on) for all components.
- Check that the encoder cables are routed in compliance with EMC.
- Check the plug connections.
- Replace encoder.
F31502
Motor encoder: Encoder with measuring gearbox without valid signals
Message class:
Position/speed actual value incorrect or not available (11)
Message value:
-
Component:
Sensor Module Encoder 1
Response:
OFF1
Acknowledgment: 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 operation.
F31503
Motor encoder: Position tracking cannot be reset
Message class:
Position/speed actual value incorrect or not available (11)
Message value:
-
Component:
None
Response:
OFF1
Acknowledgment: IMMEDIATELY
Cause:
The position tracking for the measuring gearbox cannot be reset.
Remedy:
The fault should be resolved as follows:
- Select commissioning.
- Reset the position tracking as follows (p0411.2 = 1).
- Deselect commissioning.
The fault should then be acknowledged and the absolute encoder adjusted.
A31700
Motor encoder: Functional safety monitoring initiated
Message class:
Safety monitoring channel has identified an error (10)
Message value:
Fault cause: %1 bin
Component:
Sensor Module Encoder 1
Response:
NONE
Acknowledgment: NONE
Cause:
Functional safety was activated. Self test of the DRIVE-CLiQ encoder has detected a fault.
Alarm value (r2124, interpret binary):
Bit x = 1: Effectivity test x unsuccessful.
Remedy:
Replace encoder.
F31802
Motor encoder: Time slice overflow
Message class:
Hardware/software error (1)
Message value:
%1
Component:
Sensor Module Encoder 1
Response:
ENCODER
Acknowledgment: IMMEDIATELY
