COMPUMOTOR Product Lines We Repair
Our engineers are trained on the full COMPUMOTOR product range. Below are the major product families we service.
COMPUMOTOR Stepper Motor Drives
Dedicated stepper motor drive modules controlling bipolar stepping motors. Common issues include microstepping resolution loss, phase winding shorts, thermal shutdown errors, and command pulse interpretation failures affecting motion accuracy in automation equipment.
COMPUMOTOR Servo Amplifiers
Precision servo control amplifiers for AC and DC servo motors. Typical faults include encoder signal loss, proportional gain drift, current loop oscillation, commutation timing errors, and power stage IGBT degradation in high-cycle industrial applications.
COMPUMOTOR PMAC Motion Controllers
Programmable Multi-Axis Controller (PMAC) for coordinated multi-axis motion. Repair needs involve firmware corruption, I/O module failures, servo loop instability, fieldbus communication dropout (CANopen, EtherCAT), and parameter memory loss.
COMPUMOTOR Interface & I/O Modules
Digital I/O, encoder input, analog command interface modules. Common failures include input signal conditioning degradation, optoisolator burnout, counter circuit malfunction, and signal isolation breakdown from electrical noise and surges.
COMPUMOTOR Stepping Motor Units
Integrated stepper motor and drive modules (NEMA 23/34 frame sizes). Failures stem from winding insulation breakdown, rotor magnet demagnetization from overheat, detent torque loss, and bearing wear causing cogging and vibration.

Common COMPUMOTOR Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMPUMOTOR equipment arriving at our workshop.
- ✓Stepper motor phase loss or no motion output — COMPUMOTOR stepper drives often suffer from shorted output stages in bipolar power bridges due to inductive voltage spikes. Worn protection diodes fail to suppress back-EMF, causing sustained phase shorts and disable conditions.
- ✓Servo amplifier oscillation and jerky motion — COMPUMOTOR servo amplifiers lose servo loop stability when proportional gain (Kp) and integral gain (Ki) calibration drifts due to aging component tolerance shifts. Encoder feedback signal jitter and commutation timing lag in power electronics trigger sustained oscillation in multi-kilohertz servo bandwidth.
- ✓PMAC controller unable to communicate with servo drives — COMPUMOTOR PMAC CANopen or EtherCAT fieldbus communication fails due to transceiver IC degradation, corrupted node IDs in firmware, or faulty termination resistors. Multi-axis systems lose axis synchronization when one drive node drops offline.
- ✓Encoder signal loss and position feedback errors — COMPUMOTOR encoder inputs degrade when optoisolator couplers age or electromagnetic noise from power stages couples into signal lines. Differential encoder cable shield breaks or connectors corrode, dropping signal amplitude below TTL thresholds.
- ✓Thermal shutdown and repeated drive lockout — COMPUMOTOR power stages generate sustained heat due to high conduction losses when MOSFET/IGBT on-resistance increases from gate oxide wear or solder joint degradation at power module contacts. Inadequate heatsink contact increases junction-to-ambient thermal resistance.
- ✓Parameter memory loss and factory configuration inaccessible — COMPUMOTOR PMAC and servo amplifiers store configuration in EEPROM that corrodes at solder joints or develops charge retention defects under humid Indian manufacturing plant conditions. Firmware CRC errors prevent parameter reload during power-up.

Frequently Asked Questions — COMPUMOTOR Repairs
Do you repair COMPUMOTOR equipment anywhere in India?+
Yes. Synchronics repairs the complete COMPUMOTOR motion control product range — stepper drives, servo amplifiers, PMAC controllers, I/O modules, and integrated stepper motors. We offer PAN India door pickup from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all other cities. All repairs are processed at our central facility in Vadodara, Gujarat.
What is the typical turnaround time for COMPUMOTOR servo amplifier repair?+
COMPUMOTOR servo amplifier repairs typically complete in 5-7 working days. This includes full functional testing with live servo motors, re-tuning of loop gains, and encoder signal validation. Express 48-hour repair is available for critical production equipment with additional charges. We maintain in-stock replacement components for common COMPUMOTOR servo modules to accelerate repairs.
Can Synchronics repair COMPUMOTOR PMAC controllers with corrupted firmware?+
Yes. Synchronics specializes in PMAC firmware recovery using JTAG and ISP programming interfaces. We extract firmware via direct memory access, restore from customer backup files or factory default images, and re-program motion profiles specific to your multi-axis application. Full motion testing validates all axes under actual load conditions.
Why does my COMPUMOTOR stepper drive intermittently lose phase power?+
Intermittent phase loss in COMPUMOTOR stepper drives typically stems from failed protection diodes in the bipolar output stage or marginal solder joints at MOSFET gate pads. Synchronics performs comprehensive power stage analysis using curve tracer testing, replaces aged diodes and semiconductors, and x-ray inspects all solder joints for micro-fractures that cause dropout under vibration.
Does Synchronics stock spare parts for COMPUMOTOR equipment?+
Synchronics maintains in-stock inventory of high-failure COMPUMOTOR components including power IGBTs, optoisolators, encoder interface ICs, servo loop amplifiers, and fieldbus transceivers. For obsolete COMPUMOTOR parts, we source equivalents from authorized distributors across India and provide engineering support for component substitution. Lead times for rare parts typically range from 10-15 days.
How do I send my COMPUMOTOR 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 COMPUMOTOR 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 COMPUMOTOR 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 COMPUMOTOR 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.
