02Faults
How AGI661 encoders usually fail
- No SSI data from a board or cable fault
- Wrong or lost position count
- 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 AGI661 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 SICK Stegmann units; Star Automations is an independent multi-brand repair company and is not an OEM service centre.
What interface does the AGI661 use?
SSI serial.
Which motors use it?
Siemens 1FT5 motors.
What should I send for a AGI661 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.
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.
