Faulty motor parameterisation. Check motor parameters.
Module ID (decimal) Error ID (decimal)
123: Motor control 14
Response (Lenze setting printed in bold) Setting: C00600 ( Adjustable response)
 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 C00173 .
• Use brake resistor or regenerative module.
• Check setting in C00173 .
Module ID (decimal) Error ID (decimal)
123: Motor control 15
Response (Lenze setting printed in bold)
 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 in C00173 .
Module ID (decimal) Error ID (decimal)
123: Motor control 16
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 that is shorter or has a lower
capacitance.
