Commutation Fuse (FD3) Commutation fuse replacement is described here.
Figure 6.23 Commutation Fuse (FD3)
Fuse (FD3) protects the commutation circuit. The cover of the drive must be removed. FD3 is
located on the top of the drive above the swing tray. The fuse is a KLKD type rated at 30 Amps
DC at 600VAC. Do not use a fuse that has a different rating.
1. Remove the fuse using a fuse puller. Replace if necessary. If a fuse continues to fail,
there may be an underlying problem.
