Common faults
What usually fails on a unit like the 6SE7023-4EC61
Encoders and resolvers tell the drive where the motor and axis are. A fault shows up as feedback alarms, position errors or a motor that won't run. Many encoders can be repaired; all need checking for correct signals and alignment.
Signal loss or noise
Damaged cables, contaminated discs or failing electronics cause intermittent feedback alarms.
Bearing and shaft wear
Worn encoder bearings cause signal jitter and eventually mechanical failure.
Contamination
Oil, coolant or dust on the code disc gives counting errors and lost position.
Absolute encoder data errors
Battery or memory faults on absolute encoders lose the stored position.
Connector damage
Bent pins and corroded connectors, common where cables are flexed or exposed.
First checks
What to check before calling an engineer
Isolate and lock out the supply, and wait for stored energy to discharge, before opening anything.
Safe for plant staff
- Check the encoder cable and connectors along their full length.
- Note the exact feedback alarm from the drive.
- Check for oil or coolant ingress at the encoder housing.
Leave to a specialist
- Opening the encoder or cleaning the code disc.
- Aligning an encoder to a motor rotor.
- Re-referencing an absolute encoder.
Getting it fixed
How to get the 6SE7023-4EC61 repaired
What to send with it
- The encoder, and the motor if the encoder is built into it.
- The drive alarm and the drive model it connects to.
- Whether the fault is constant or intermittent.
Onsite or ship-in
Technicians work onsite from our Hyderabad base and travel to plants across India; anything that can be removed can also be sent to MachineryFix from anywhere in the country.
Warranty. Repairs carry a warranty of 30 days to 6 months, depending on the item and the repair; the exact term is confirmed before work starts.
FAQ
6SE7023-4EC61 repair questions
Does the Siemens 6SE7023-4EC61 need to be aligned after repair?+
If it mounts on a servo motor, yes: it has to be aligned to the rotor so the drive commutates correctly. That is part of the repair when the motor is sent too.
Does the Siemens 6SE7023-4EC61 have to be sent in, or can an engineer come to the plant?+
Either. An engineer can diagnose it in place and repair it there or take it away, or the unit can be sent to MachineryFix from anywhere in India. The diagnosis and repair cost are confirmed before any work starts.
Is MachineryFix connected to Siemens?+
No. Siemens and the model name are used only to identify the equipment. MachineryFix is an independent repair service and is not affiliated with or endorsed by Siemens.
