FANUC Alarm LECO-053 — Cap B over voltage (Cap A volts, Cap B volts)

Description

The voltage on one of the two input capacitor banks (bank B) has exceeded the high voltage limit. This is normally caused by high input voltage but it could be caused by a faulty switch board, main capacitor, contactor, or V-to-F feedback signal.

Remedy · Remède

Check the input power (voltage and frequency). Verify the primary reconnect is properly configured for the input voltage.
