Response (Lenze setting printed in bold)
None System fault Fault Trouble Quick stop by trouble Warning locked Warning : Information
Cause Remedy
Faulty motor parameterisation. Check motor parameters.
Response (Lenze setting printed in bold)
None System fault : Fault Trouble Quick stop by trouble Warning locked Warning Information
Cause Remedy
Absolute value encoder does not send any data. • Check supply cable.
• Check encoder.
• Check voltage supply ( C00421 ).
Response (Lenze setting printed in bold)
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.
• Check encoder cable.
• Check encoder.
• Check parameter setting ( C00422 ).
• Switch off monitoring, if necessary ( C00580 ="3").
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 brake operations. Check drive dimensioning.
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 brake operations. • Check drive dimensioning.
• Check parameter setting ( C00129 , C00130 , C00131 ,
C00132 ).
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 ).
