Tamagawa and Panasonic encoder repair: TS5643 to TS5781, MFE0017, MFE2500
Tamagawa makes the encoders inside Panasonic, Toshiba, Shibaura, Nachi, Shinko, Kobelco and many robot and machine-tool servo motors, often under the Panasonic MFE name. We test the serial count and status, repair or replace the encoder, and align it so the motor runs on its own drive.
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.
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 these encoders usually fail
- Serial communication errors from water or coolant on the board
- Battery-related multi-turn loss on absolute types
- Encoder board damaged by a wrong cable or shorted 5 V supply
- Count errors from a contaminated or cracked disc
- Connector pins pushed back on small JST or AMP connectors
03Identify
Reading the label
Tamagawa part numbers start with TS, followed by four digits and an N suffix for the variant, such as TS5667N100. Panasonic motors often show only the MFE number. The older SA and OA codes, such as SA48 or OAM74, describe the encoder family.
04Motors

Open06FAQ
Questions
Is MFE0017 the same as a Tamagawa encoder?
Yes, it is a Tamagawa serial encoder of the TS5667 family supplied under a Panasonic code.
My Panasonic motor shows an encoder communication alarm. Can it be repaired?
Often, yes. We check the cable and connector first, then the encoder board. If the encoder itself has failed we replace and align it.
Do you repair robot motors with Tamagawa encoders?
Yes, including Nachi, Shinko and Kobelco robot axis motors.

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.
