Cause : Power Supply Frequency Fault comes when the input power supply frequency exceeded the allowable frequency fluctuation.
- A momentary power loss occurred. Reset the fault.
- An input power supply wiring terminal is loose. Check for loose terminals.
- The built-in fuse is open. Replace either the control board or the entire drive.
