None System fault Fault Trouble Quick stop by trouble Warning locked Warning Information
Cause
Remedy
Due to a too high braking energy, the DC-bus voltage
exceeds the overvoltage threshold which results from
the mains voltage setting in
• Use brake resistor or regenerative module.
• Check setting in

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 that is shorter or has a lower
capacitance.
