U

Energy Supply Stop (ECM)

Fanuc · Alpha i Series AC Servo Motor and Spindle

Hva betyr U ?

A potential difference across a capacitor module is more than 300V, indicating an energy supply issue or abnormal voltage condition.

Vanlige årsaker

  • Charging current exceeds the allowed limit.
  • Faulty charging circuit or power supply.
  • Capacitor bank is not charging efficiently.
  • Overcharging the capacitor module.
