Rexroth DKC Ecodrive Fault Codes

Rexroth DKC Ecodrive Fault Codes

The following Bosch Rexroth Indramat fault codes apply to DKC drive systems. These codes indicate electrical overloads, communication failures, temperature warnings, internal component faults, and power section issues.

If your drive displays one of the fault codes below and will not reset, professional diagnostic repair may be required.

What To Do If Your Indramat Drive Shows a Fault Code

Record the exact fault number displayed.

Attempt a system reset if safe to do so.

If the fault returns, internal component damage may be present.

Many legacy Indramat DKC drives remain repairable, even if discontinued.
