Printable reference sheets from our repair bench: encoder types and counts, an alignment checklist, an alarm quick sheet, a feedback selection guide for motor makers, and a send-in form for repairs. Free PDFs, no sign-up.
Encoder families, interfaces, counts per revolution and the motors they sit on: Fanuc pulsecoders (alpha A64, A1000), Mitsubishi OBA/OSA, Yaskawa UTOPH, Tamagawa, Heidenhain ECN/EQN/ERN and SICK SKS/SRS/SRM.

Manufacturer datasheets, encoder pin-outs and cable diagrams belong to the manufacturer, so we do not post them here. If you send the motor or encoder nameplate, we check our files and send what we have for that model, usually the same working day.
This is also the quickest way to get a repair quote: the same photo tells us whether the motor can be repaired.
Step by step, with the readings to record.
OpenWhat the common alarm codes usually mean.
OpenHow each works and where it is used.
OpenCost, lead time and when replacement makes sense.
OpenNo. Every PDF on this page downloads directly. Print them, keep them in the maintenance file, share them with your team.
Send us the nameplate photo on WhatsApp. If we have the manufacturer datasheet or a wiring diagram for that model on file, we send it with the quote. We do not publish manufacturer datasheets here because they belong to the manufacturer.
No. They help you find out whether the fault is in the motor, the encoder, the cable or the drive before anything is removed from the machine. If the motor or encoder is faulty, it needs a bench test and repair.
Start with the encoder alarm quick sheet. It tells you which alarms usually point to the cable or connector, which ones point to the encoder, and which ones need the motor on a test bench.
Yes. It was written for motor makers and machine builders choosing between Hall sensors, incremental encoders, absolute encoders and resolvers. Call us if you need help matching a feedback device to a drive.
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.
Our team replies by email or WhatsApp, usually the same working day. For a line-down motor, WhatsApp +91 97866 22233.
