None System fault Fault : Trouble Quick stop by trouble Warning locked Warning Information
Cause Remedy
• Since the braking energy is too high, the DC-bus
voltage is higher than the overvoltage threshold
which results from the mains setting in C00173 .
• Use brake resistor or feedback module.
• Check setting under C00173 .

None System fault Fault : Trouble Quick stop by trouble Warning locked Warning Information
Cause Remedy
DC bus voltage is lower than the undervoltage threshold
resulting from the mains setting under C00173 .
• Check mains voltage.
• Check setting under C00173 .
Response (Lenze setting printed in bold)
None System fault : Fault Trouble Quick stop by trouble Warning locked Warning Information
Cause Remedy
• Short circuit/earth fault in motor cable.
• Excessive capacitive charging current in the motor
cable.
• Check motor cable.
• Use motor cable which is shorter or has a lower
capacitance.
