Response (Lenze setting printed in bold) Setting: C00580 ( Adjustable response)

 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).

Response (Lenze setting printed in bold)

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information

Cause Remedy

Too frequent and too long braking processes. • Check drive dimensioning.

• Check parameter setting (C00129

, C00130, C00131).

123: Motor control 30

Response (Lenze setting printed in bold) Setting: C00619 ( Adjustable response)

 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

).
