Indramat MDD, MHD, MKD and MKE encoder and resolver repair
Indramat digital motor feedback is a Serial encoders and resolvers with memory data encoder with 1,024 or 2,048 counts per turn for the encoder types. We test it, repair or replace it and align it to the rotor. Found on: Indramat MDD, MHD, MKD and MKE digital motors. Star Automations is an independent multi-brand repair company and is not an OEM service centre.

01Facts
Indramat digital motor feedback at a glance
| Device | Indramat digital motor feedback |
|---|---|
| Brand family | Indramat |
| Type and format | Serial encoders and resolvers with memory data |
| Counts | 1,024 or 2,048 counts per turn for the encoder types |
| Found on | Indramat MDD, MHD, MKD and MKE digital motors |
| Connector | Per motor model |
| Pole setting for alignment | 2 to 8 selectable |
Indramat digital motors (part numbers starting MDD, MHD, MKD and MKE) use serial encoder and resolver feedback that includes memory data identifying the motor to the drive. Older MAC motors are simpler: Hall effect commutation, an incremental encoder and a tachometer.

02Faults
How Indramat digital motor feedback encoders usually fail
- No serial data from a board or cable fault
- Memory data unreadable, so the drive cannot identify the motor
- Resolver winding or connector fault
- Alignment that no longer matches the rotor
03Process
How the repair is done
Receive and identify
We read the nameplate and encoder label and confirm the exact type.
Test
Count per turn, data status, alarm flags and, where fitted, incremental lines are checked on the bench.
Repair or replace
Board, connector or sensor faults are repaired; a matched encoder is fitted where repair is not sensible.
Align
Commutation is set to the rotor and checked at every pole pair using the electrical angle.
Verify and report
The motor is run on the bench and the readings are recorded in the report.
See encoder alignment, memory programming and replacement.
05FAQ
Questions
Can you repair a Indramat digital motor feedback encoder?
Yes. We test the position count and status, repair or replace the encoder, align it to the rotor and run the motor. We repair Indramat units; Star Automations is an independent multi-brand repair company and is not an OEM service centre.
Do you repair MAC motors?
Yes. MAC motors use Hall sensors, an incremental encoder and a tachometer, which we test and repair.
What does the memory data do?
It identifies the motor to the drive, so it must be intact for the motor to run.
What should I send for a Indramat digital motor feedback enquiry?
A clear photo of the motor nameplate and, if the cover is off, the encoder label. You can send the motor or only the encoder.
Model pages
Facts, counts and typical motors for individual encoder types.
06Enquiry
Send the nameplate or encoder label
A clear photo of the motor nameplate and, if the cover is off, the encoder label is enough to start. We reply with whether it can be repaired and a quote.
