Mitsubishi FR-SF Power Supply Troubleshooting

SF-PW Procedure

This is to determine the cause of why the FR-SF drive is not powering up and showing no LED display. 

  1. Remove SF-CA control board from FR drive.
  2. Turn on power to drive.
  3. Locate the yellow/amber LED on the power supply.
  4. If LED is on, then the problem with power is with the control board. If LED is off, then the power supply is the problem.
