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

02Faults

How Pulsecoder Beta I32B / A32B 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 Beta I32B / A32B 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 DB15 or a two-row AMP D3100 connector.

What replaced them?

BetaM motors use the I64B and A64B encoders.

What should I send for a Pulsecoder Beta I32B / A32B 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.
