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.

Emergency: same day

For a line-down motor, where the fault and parts allow. WhatsApp us before you send it so the bench is kept free.

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

Alpha i motors use Alpha i encoders. They look very similar to the Alpha encoders in the newer package and the data is very similar, but they connect through a small 10 pin circular connector.

02Faults

How Pulsecoder Alpha I64i / A64i encoders usually fail

  • No data received from the encoder at power-up, usually a cable, connector or encoder board fault
  • Internal error flag set by the encoder, which normally means repair or replacement
  • Battery alarm or lost absolute position after a backup supply fault
  • Overheat flag stuck on after thermal line or board damage
  • Count that does not match one revolution, or commutation that no longer lines up with the rotor
03Process

How the repair is done

  1. Receive and identify

    We read the nameplate and encoder label and confirm the exact type.

  2. Test

    Count per turn, data status, alarm flags and, where fitted, incremental lines are checked on the bench.

  3. Repair or replace

    Board, connector or sensor faults are repaired; a matched encoder is fitted where repair is not sensible.

  4. Align

    Commutation is set to the rotor and checked at every pole pair using the electrical angle.

  5. 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 Pulsecoder Alpha I64i / A64i 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 Fanuc units; Star Automations is an independent multi-brand repair company and is not an OEM service centre.

What connector do they use?

A small 10 pin circular JAE connector.

What is the resolution?

65,536 counts per turn.

What should I send for a Pulsecoder Alpha I64i / A64i 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.

We use these details to reply to your enquiry. See our privacy policy.
