Resistor Module Abnormal Discharge (1) (ECM)

Fanuc · Alpha i Series AC Servo Motor and Spindle

Hva betyr F ?

The Capacitor Modules are not discharging as expected, indicating a potential malfunction of the discharge circuit or the Resistor Module itself.

Vanlige årsaker

  • The braking resistor module is experiencing an abnormal discharge condition (first instance).
  • Faulty braking resistor element or connection.
  • Internal control signal error related to braking resistor activation.
  • Over-temperature detected within the braking resistor module.
  • Unexpected rapid discharge of energy through the resistor.
