Encoders & Resolvers repair
Incremental and absolute encoders, resolvers and linear feedback devices on motors and axes. Encoders and resolvers tell the drive where the motor and axis are. A fault shows up as feedback alarms, position errors or a motor that won't run. Many encoders can be repaired; all need checking for correct signals and alignment.

Common faults
What usually fails on Encoders & Resolvers
Signal loss or noise
Damaged cables, contaminated discs or failing electronics cause intermittent feedback alarms.
Bearing and shaft wear
Worn encoder bearings cause signal jitter and eventually mechanical failure.
Contamination
Oil, coolant or dust on the code disc gives counting errors and lost position.
Absolute encoder data errors
Battery or memory faults on absolute encoders lose the stored position.
Connector damage
Bent pins and corroded connectors, common where cables are flexed or exposed.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Check the encoder cable and connectors along their full length.
- Note the exact feedback alarm from the drive.
- Check for oil or coolant ingress at the encoder housing.
Leave to a specialist
- Opening the encoder or cleaning the code disc.
- Aligning an encoder to a motor rotor.
- Re-referencing an absolute encoder.
Warranty. Repairs carry a warranty of 30 days to 6 months, depending on the item and the repair; the exact term is confirmed before work starts.
FAQ
Encoders & Resolvers repair questions
Does the encoder need to be aligned after repair?+
If it mounts on a servo motor, yes: it has to be aligned to the rotor so the drive commutates correctly. That is part of the repair when the motor is sent too.
