TAMAGAWA Equipment We Repair — By Category
TAMAGAWA Product Lines We Repair
Our engineers are trained on the full TAMAGAWA product range. Below are the major product families we service.
Absolute Multiturn Encoders
Tamagawa's TS5000 and TS5500 series multiturn encoders provide absolute position feedback over multiple shaft revolutions. Common failures include battery depletion in battery-backed versions, SSI/CANopen communication faults, and mechanical wear on coupling interfaces.
Incremental Rotary Encoders
Tamagawa TRD series incremental encoders deliver A/B phase and index outputs for servo and spindle feedback. Typical repair issues include encoder connector corrosion, phototransistor degradation, and contamination of optical disk surfaces in harsh industrial environments.
Resolver Units
Tamagawa resolvers (TRD-R series) convert angular position to analog sine/cosine voltages for legacy motion control systems. Repair focuses on primary/secondary winding insulation breakdown, slip ring contamination, and resolver-to-digital converter interface faults.
CANopen and Fieldbus Encoders
Tamagawa's TS5640F and TS5645F CANopen encoders are widely deployed in Indian automotive assembly lines. Common faults include CANopen communication timeouts, firmware corruption, and connector pin oxidation in high-vibration production floors.
Hollow-Shaft Encoders
Tamagawa hollow-shaft versions (TARA/TARS series) mount directly on motor shafts in space-constrained applications. Repair involves re-centering mechanical runout, replacing worn brush contacts, and addressing capacitive coupling noise in long cable runs.
Sine/Cosine Analog Encoders
Tamagawa TSA series analog encoders output continuous sine/cosine signals for high-resolution position interpolation. Failures include amplifier output drift, reference voltage instability, and signal conditioning circuit degradation in temperature-extreme environments.

Common TAMAGAWA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TAMAGAWA equipment arriving at our workshop.
- ✓Encoder signal loss or intermittent dropouts — Tamagawa encoder connectors (M12/M23) corrode in humid or salt-spray environments common in Indian coastal manufacturing zones. Oxidized pins degrade signal integrity, causing intermittent A/B phase loss or SSI communication failure.
- ✓Absolute encoder position drift or error codes — Tamagawa absolute multiturn encoders (TS5000/TS5500) suffer battery drain or internal memory corruption, especially in units operating continuously without power cycles. SSI checksum errors or CANopen NMT timeout faults indicate firmware or non-volatile memory issues.
- ✓Resolver sine/cosine output instability — Tamagawa resolver slip rings accumulate conductive dust in textile mills, steel plants, and cement facilities common across Indian industrial clusters. Primary/secondary winding insulation also degrades from thermal stress and vibration-induced micro-fractures.
- ✓CANopen encoder communication timeout — Tamagawa TS5640F/TS5645F CANopen encoders fail to respond to heartbeat or process image requests. Root causes include firmware corruption from power surges, CANopen stack initialization failure, or clock oscillator drift in extremes of Indian ambient temperature (35-50 deg C).
- ✓Optical disk contamination and phototransistor failure — Tamagawa incremental encoders (TRD-MA series) in CNC shops and automotive manufacturing accumulate coolant mist, metal swarf, and dust on optical surfaces. Phototransistors degrade from thermal aging and extended exposure to infrared from nearby heat sources.
- ✓Mechanical coupling runout and bearing wear — Hollow-shaft Tamagawa encoders (TARA/TARS series) develop runout when motor shaft concentricity tolerances drift due to bearing wear or improper installation. Radial play >0.15mm causes timing errors in servo feedback loops and cumulative position errors in multi-axis machines.

Frequently Asked Questions — TAMAGAWA Repairs
Do you repair Tamagawa encoders anywhere in India?+
Yes. Synchronics repairs the complete Tamagawa encoder range — absolute multiturn, incremental rotary, resolvers, CANopen fieldbus, and hollow-shaft variants. We offer same-week turnaround and PAN India pickup from Vadodara facility. Door service available from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, Kolkata, and all major industrial cities.
What is the typical repair cost and timeline for a Tamagawa TS5000 absolute encoder?+
Absolute encoder repairs typically cost Rs. 8,000-15,000 depending on failure type (battery replacement, firmware reload, winding repair). Standard turnaround is 3-5 working days. Emergency expedite available 24-48 hours. Synchronics provides advance cost estimate with photo diagnosis before repair begins — zero surprises.
Can Synchronics repair Tamagawa encoders with custom firmware or application-specific configurations?+
Yes. Our engineers have access to Tamagawa firmware development kits and SSI/CANopen protocol stacks. We support custom encoder configurations for automotive OEMs, robot integrators, and machine builders across India. We provide technical documentation and verification test reports confirming firmware compliance with your original equipment specifications.
How do I know if my Tamagawa encoder is worth repairing versus replacement?+
Synchronics performs free failure analysis within 24 hours of receipt. For encoders >5 years old with bearing wear or phototransistor aging, replacement may be cost-effective. For newer units with connector corrosion, firmware faults, or mechanical runout, repair typically saves 60-70% versus new encoder cost. We email detailed recommendation with repair/replace ROI analysis.
Do you offer Tamagawa encoder calibration and traceability certificates?+
Yes. Synchronics calibrates all repaired Tamagawa encoders against NIST-traceable standards using precision spindle and laser runout gauges. We issue calibration certificates with accuracy statements, uncertainty budget, and measurement data. Certificates valid for 12 months and accepted by automotive OEMs (IATF 16949) and pharmaceutical GMP audits.
How do I send my TAMAGAWA unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a TAMAGAWA drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on TAMAGAWA repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your TAMAGAWA unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
