"OF" Displayed on Keypad

This guide will walk you through the steps to understanding and resolving the "OF" message displayed on your EG-260 keypad.

"OF" is a fault message indicating a short circuit on the output of the VFD or a failed output transistor inside the VFD itself. Have qualified personnel inspect the wiring at the VFD output as well as at the motor leads. Qualified personnel should also inspect the motor itself for defects. If wiring and motor are determined to be in correct working order the VFD must be replaced.
