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 ).
Response (Lenze setting printed in bold)
 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
Brake chopper short circuit/earth fault detected. Check brake chopper cable and brake resistor.

 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
Interruption of phase L1 of the mains cable.
• Up to software version V02.00.19 a fault is reported if
a mains phase failure occurs.
• From software version V02.00.20 a trouble is reported
for mains phase failures < 500 ms. If the mains phase
failure is pending longer than 500 ms, the device
changes to the "Fault" status.
If the fault is pending longer and the device reports a
fault, check the cabling between the regenerative power
supply module and the mains.

Cause Remedy
Interruption of phase L2 of the mains cable.
• Up to software version V02.00.19 a fault is reported if
a mains phase failure occurs.
• From software version V02.00.20 a trouble is reported
for mains phase failures < 500 ms. If the mains phase
failure is pending longer than 500 ms, the device
changes to the "Fault" status.
If the fault is pending longer and the device reports a
fault, check the cabling between the regenerative power
supply module and the mains.

Cause Remedy
Interruption of phase L3 of the mains cable.
• Up to software version V02.00.19 a fault is reported if
a mains phase failure occurs.
• From software version V02.00.20 a trouble is reported
for mains phase failures < 500 ms. If the mains phase
failure is pending longer than 500 ms, the device
changes to the "Fault" status.
If the fault is pending longer and the device reports a
fault, check the cabling between the regenerative power
supply module and the mains.
