Remedy: - Carry out a POWER ON (switch-o/switch-on) f
or 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 commis
sioning.
- Reset t
he position tracking as follows (p0411.2 = 1).
- Deselect commissioning.
The fault should then be acknowledged and the absolute encoder adjusted.
