HC fault in inovance MD290 drive - The AC drive display is normal upon power-on, but after running the AC drive displays "HC" and stops immediately.

  1. The cooling fan is damaged or does not rotate.
  2. Replace the damaged fan.
  3. The cable of the external control terminal is short-circuited.
  4. Eliminate the external short-circuit fault.
