Omron R7M-Z servo motor repair
Star Automations repairs Omron R7M-Z servo motors (SMARTSTEP 2). The motor is inspected, the failed parts are repaired or replaced, the encoder is aligned where needed, and the motor is proved on our servo motor test system with a no-load run and a load test before it leaves our bench. Send the nameplate and we confirm repairability first. Star Automations is an independent multi-brand repair company and is not an OEM service centre.
01Failures
Common Omron R7M-Z failures
Encoder and feedback faults
Encoder communication errors that raise drive alarms.
Bearing noise
High-cycle axes wear bearings early; noise and heat show first.
Brake faults
Brakes that drag on release or slip when holding a load.
Cable and connector damage
Flexing in cable chains breaks feedback and power leads at the motor connector.
02Test bench
What the test bench checks
- Insulation resistance and hi-pot
- Winding resistance and balance
- Encoder or resolver feedback and commutation offset
- Brake release and holding, where fitted
- No-load run, then load run; speed and current against the nameplate
- Vibration and noise at rated speed
03Repair or replace
Repair or replace
Repair suits motors where the frame and shaft are sound and the fault is the encoder, bearings, brake or connector, which covers most Omron R7M-Z motors that reach us.
Replacement suits motors with a damaged shaft, weak magnets or a winding that fails insulation tests. We say which applies after inspection, before any work starts.

06Questions
Omron R7M-Z questions
Do you repair Omron R7M-Z servo motors?
Yes. Send the nameplate and we confirm repairability before you courier.
What should I send for a quote on a R7M-Z motor?
A photo of the nameplate, the alarm code and a note on the symptom, such as the fault on the drive or what the axis was doing when it stopped.
Do you need the Omron drive to test the motor?
No. Our servo motor test system runs the motor without the original drive, then a load rig applies load.
Can you repair the encoder or feedback device?
Where the fault is in the feedback device, we repair or replace what failed and align the encoder before the load test.
Is there a warranty?
A written warranty is given after a successful repair. Warranty terms are stated on each quotation.
