 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
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 ( C00422 = "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 C00580 is triggered.
• Check encoder cable.
• Check encoder.
• Check parameter setting ( C00422 ).
• Switch off the monitoring function ( C00580 ="3") if no
encoder is used.
• Correct the light path (for laser measuring systems).
• Improve the reflection (for laser measuring systems).

Cause Remedy
Too frequent and too long braking processes. • Check drive dimensioning.
• Check parameter setting ( C00129 , C00130 , C00131 ).

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
The instantaneous value of the motor current has
exceeded the value set in C00620 .
• Set a higher value in C00620 .
• Reduce maximum current ( C00022 ).
• Change response ( C00619 ).
