Cause
Remedy
• Encoder cable interrupted.
• Encoder defective.
• Faulty parameter setting of the encoder.
• Interruption of the light path of laser measuring
systems.
• Insufficient reflection of the light of laser measuring
systems.
Note:
The encoder open-circuit monitoring for incremental
encoders (
= "0: Incremental encoder (TTL
signal)") requires a signal amplitude > 3.5 V!
If the signal amplitude is lower than 3.0 V, the error
response parameterised in
• Check encoder cable.
• Check encoder.
• Check parameter setting (
).
• Switch off the monitoring function (
="3") if no
encoder is used.
• Correct the light path (for laser measuring systems).
• Improve the reflection (for laser measuring systems).
