Indramat DSF Stegmann SCS70 encoder repair
DSF SCS70 (Stegmann) is a Stegmann Hiperface single-turn and multi-turn encoder with 2,048 counts per turn. We test it, repair or replace it and align it to the rotor. Found on: Indramat MDD motors and 2AD spindle motors. Star Automations is an independent multi-brand repair company and is not an OEM service centre.

The DSF0XSN-S and DSF0XMN-S feedback units use the Stegmann SCS70, single-turn and multi-turn, on MDD motors and 2AD spindle motors.
02Faults
How DSF SCS70 (Stegmann) encoders usually fail
- No serial data from a board or cable fault
- Memory data unreadable, so the drive cannot identify the motor
- Wrong or lost position count
- Alignment that no longer matches the rotor
02+Alarms
DSF SCS70 (Stegmann) alarms and error codes: what they mean and what to check
These are the alarms most often seen with the DSF SCS70 (Stegmann) 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 |
|---|---|---|
| Status 01 | Analog signals outside the allowed range | Supply and cable first; then contamination or failing electronics |
| Status 02 or 03 | Internal angle offset wrong, or the data field table is damaged | Encoder memory fault; needs encoder repair or reprogramming |
| Status 05 or 06 | Internal bus or internal checksum fault | Encoder electronics; send for test |
| Status 07 | The encoder was reset by its own watchdog | Check supply dips and noise; if it repeats, the electronics |
| Status 08 | Counter overflow | Set the reference position again |
| Status 09 or 0A | Parity or checksum error on the serial line | Cable, shield and serial settings, then the encoder |
| Feedback communication fault on the drive (for example Kinetix S45) | The drive gets no usable answer from the encoder | Connector pins, shield clamps and cable, then the encoder |
| Motor data mismatch after replacement | The data stored in the encoder does not match the motor data the drive expects | The encoder memory must carry the right motor data; this is a programming step, not a wiring fault |
The status numbers come from the Hiperface protocol; how the drive shows them depends on the drive brand. 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.

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 DSF SCS70 (Stegmann) 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 DSF SCS70 (Stegmann) 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 DSF SCS70 (Stegmann) 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 Indramat units; Star Automations is an independent multi-brand repair company and is not an OEM service centre.
Is the SCS70 on spindle motors too?
Yes, on 2AD spindle motors.
Where is the plain SCS/SCM page?
See the SICK Stegmann SCS60/70 and SCM60/70 page.
What should I send for a DSF SCS70 (Stegmann) 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.
