External fault

Was bedeutet 51 ?

A digital input that has been configured as an external fault input has become active. This means an external device connected to this input has signaled a fault condition to the frequency converter.

• DC bus voltage exceeds the drive's maximum safe limit (e.g., P0205).
• Regenerative braking energy too high for the DC bus to dissipate.
• Line voltage surge during power-up.
• Faulty braking resistor or chopper circuit.
• Capacitor bank failure in the DC link.
