02Faults
How SA48 TS5667 encoders usually fail
- No serial data, usually a cable, connector or board fault
- Absolute count lost after a battery fault
- Incremental A, B or Z channel missing or weak
- Alignment that no longer matches the rotor after a repair or swap
02+Alarms
SA48 TS5667 alarms and error codes: what they mean and what to check
These are the alarms most often seen with the SA48 TS5667 feedback device, with what each usually means and what to check first. Many encoder alarms are caused by the cable, connector or battery, not the encoder, so the checks below can save a repair.
| Alarm | Usually means | Check first |
|---|---|---|
| Encoder communication or no-data alarm | The drive receives no serial data from the encoder | Connector, cable, supply voltage; then the encoder board |
| Encoder data or checksum alarm | Serial frames arrive corrupted | Noise, shield and earthing; then the encoder |
| Incremental A or B signal alarm | The count and the serial position disagree | Cable and connector; then the encoder |
| Overheat alarm from the encoder | Temperature flag set | Motor temperature and cooling; stuck flag points to the encoder board |
| Alarm after a motor or encoder change | Motor data or alignment does not match | Check the motor type setting and the encoder alignment |
Alarm numbers differ between drive series, so the list is by situation rather than number. Match what your alarm text says. Alarm numbers and wording change with drive series and firmware, so check the manual for your drive. Drive brand names are used only to identify alarm lists. Star Automations is an independent multi-brand repair company and is not an OEM service centre.
Typical causes and checks
- Alarm at every power-up: reseat the connector at both ends, check the encoder supply at the motor end, and look for a broken wire.
- Alarm only when the axis moves or the cable flexes: suspect a break inside the cable chain, or a shield that has come loose.
- Alarm after coolant, washdown or rain: look for moisture or corrosion in the connector and behind the encoder cover.
- Alarm at random with other drives running: check earthing and shield clamps, and keep the feedback cable away from power cables.
- Alarm after a motor, encoder or drive change: check the type, the motor data in the drive, and the encoder alignment.
Encoder, cable or drive?
Swap in a known-good feedback cable first. If the alarm stays, move the motor to another axis if the drives are the same type. If the alarm follows the motor, the encoder or motor needs testing. If it stays on the axis with a good motor and cable, the drive needs testing. We test the encoder, the motor and the drive, so send the nameplate if you are not sure which it is.

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
What do encoder alarms on a SA48 TS5667 usually mean?
Most fall into four groups: no communication, corrupted data, a fault reported by the encoder itself, and a position or commutation mismatch. The alarm table on this page lists the common codes and the first check for each.
How can I tell whether the SA48 TS5667 encoder, the cable or the drive is at fault?
Swap in a known-good feedback cable, then move the motor to another axis if possible. If the alarm follows the motor, the encoder needs testing; if it stays on the axis, the drive does. A cable or battery fault can be fixed without sending anything.
Can you repair a SA48 TS5667 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 Tamagawa units; Star Automations is an independent multi-brand repair company and is not an OEM service centre.
What are the TS5647 and TS5648?
Related Tamagawa serial encoders at 65,536 and 1,048,576 counts per turn.
Can I send just the encoder?
Yes, with the motor nameplate if available.
What should I send for a SA48 TS5667 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.
