Cause : INV DISABLED comes when optional DC switch has opened while unit was stopped, which is used to disconnect the drive from the DC bus, has opened. This can happen for a variety of reasons, and it needs to be addressed to ensure the proper functioning of the drive.
- Close DC switch.
- Check AFSC-0x Fuse Switch Controller unit.
