Heidenhain EQN 1325 encoder repair, test and alignment
EQN 1325-2048 is a EnDat serial (also SSI type) encoder with 8,192 per turn, multi-turn counts. We test it, repair or replace it and align it to the rotor. Found on: Siemens, Baldor, Bosch Rexroth and B&R servo systems; Indramat MHD motors. Star Automations is an independent multi-brand repair company and is not an OEM service centre.

Repair turnaround you can plan around
Send a photo of the nameplate first. We confirm whether the motor is repairable, and the quote, the same working day.
Urgent: 3 working days
Repair, encoder alignment and test, counted from the day the motor reaches the bench and the quote is approved.
Standard: 7 working days
Full repair, encoder alignment, run test under load and a printed test report.
- Free repairability check from a nameplate photo
- Printed test report with every motor
- Written warranty, terms stated on every quotation
- Pickup can be arranged; parts that must be imported are quoted with their own timeline

The EQN 1325-2048 is the multi-turn partner of the ECN 1313. An SSI version of the same type is used on Stromag drives.
02Faults
How EQN 1325-2048 encoders usually fail
- Reduced 1 V p-p sine or cosine amplitude from a dirty or damaged scanning unit
- No EnDat data
- Wrong signal level on the incremental tracks
- Alignment that no longer matches the rotor
- Multi-turn count lost
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 EQN 1325-2048 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 Heidenhain units; Star Automations is an independent multi-brand repair company and is not an OEM service centre.
Is there an SSI version?
Yes, the EQN 1325-2048 SSI type used on Stromag drives.
Does it hold motor data in memory?
Memory content varies by motor maker; we check and, where needed, restore it.
What should I send for a EQN 1325-2048 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.
