Resistor Module Abnormal Discharge (2) (ECM)

Fanuc · Alpha i Series AC Servo Motor and Spindle

Was bedeutet H ?

The Capacitor Modules are not discharging due to a malfunction of the discharge circuit. This points to a failure within the Resistor Module's components or control.

Häufige Ursachen

  • The braking resistor module is experiencing an abnormal discharge condition (second instance).
  • Persistent fault in the braking resistor system.
  • Contradictory signals from the braking resistor monitoring system.
  • Component failure within the braking resistor control or sensing circuitry.
  • Improper heat dissipation from the resistor, leading to thermal issues.
