MICROTROL Equipment We Repair — By Category
MICROTROL Product Lines We Repair
Our engineers are trained on the full MICROTROL product range. Below are the major product families we service.
Stepper Motor Drivers (MD Series)
Microtrol MD-series stepper drivers deliver microstepping resolution and precise current control for positioning applications. Common failures include burnt gate drivers, capacitor drying, and loss of microstepping resolution due to driver IC degradation in high-heat plant environments.
Motion Control Modules (MCM Series)
MCM-series modules integrate step-direction control with resolver feedback for closed-loop stepper and servo systems. Typical faults include resolver signal loss, timing circuit failures, and firmware corruption affecting ramp-rate programming.
Pulse Rate Multiplier Cards (PRM Series)
PRM-series cards convert low-frequency input signals into high-frequency stepper pulses, essential for legacy textile looms and multi-axis packaging machinery. Prone to capacitor failure and logic IC burnout under high-vibration industrial conditions.
Servo Amplifiers (SA Series)
Microtrol SA-series servo amplifiers provide analog-to-PWM conversion for servo motor control in precision tool changers and robotic arms. Failures often stem from MOSFET bridge degradation, feedback offset drift, and thermal runaway under sustained high torque.
Step/Direction Controller (SDC Series)
SDC-series standalone controllers generate synchronized step and direction signals for multi-axis stepper systems in CNC machines and automatic assembly lines. Common issues include timing skew, loss of direction logic, and watchdog timer resets under EMI.

Common MICROTROL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MICROTROL equipment arriving at our workshop.
- ✓Stepper driver gate driver burnout under overload — Microtrol MD-series drivers fail when phase current exceeds design limits or thermal shutdown activates repeatedly. Oversized stepper motors or jamming conditions cause sustained overcurrent, destroying the gate drive IC (typically IR2110 or equivalent).
- ✓Microstepping resolution loss and vibration — Microtrol stepper drivers lose microstepping when DAC-conversion circuits degrade or timing oscillators drift due to capacitor aging. Common in textile machinery where dust ingress accelerates electrolytic capacitor drying.
- ✓Resolver signal dropout and position loss — MCM-series closed-loop controllers lose resolver feedback due to failed input buffer amplifiers, damaged signal conditioning circuits, or broken resolver connectors in vibration-prone packaging lines. Signal amplitude drops below detection threshold.
- ✓Pulse multiplier frequency instability and phase jitter — PRM-series multipliers suffer oscillator drift and phase-lock-loop instability when the crystal timing reference ages or main filter capacitors lose capacitance. High ambient temperature in textile factories accelerates this degradation.
- ✓Servo amplifier MOSFET bridge failure and thermal runaway — Microtrol SA-series amplifiers fail when PWM MOSFETs exceed junction temperature due to inadequate heatsinking or prolonged stalled-rotor conditions. Gate drive timing skew can also cause shoot-through current and MOSFET thermal destruction.
- ✓Step/direction timing skew and axis synchronization error — SDC-series controllers generate stepped or missing pulses when internal delay circuits fail or when digital logic cells degrade from thermal cycling. EMI-induced latch-up in CMOS logic can reset the timing counter.

Frequently Asked Questions — MICROTROL Repairs
Do you repair Microtrol equipment anywhere in India?+
Yes. Synchronics repairs the full Microtrol product range — stepper drivers, servo amplifiers, motion controllers, and pulse multipliers across every Indian state. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and all other cities. All repairs are completed at our fully equipped facility in Vadodara, Gujarat, with 48-72 hour turnaround for most Microtrol drives.
Can you repair Microtrol stepper drivers without the original manual or schematic?+
Absolutely. Synchronics engineers have reverse-engineered Microtrol stepper drive architectures across the MD, MCM, and PRM series. We perform non-destructive component tracing to map circuit topology, identify failed ICs using micro-inspection, and rebuild driver logic from first principles. We then issue detailed repair reports documenting all replaced components and test results.
What is the typical cost and time to repair a Microtrol stepper driver?+
Microtrol stepper driver repairs typically cost INR 3,500 to 8,500 depending on component damage and complexity. Simple failures (gate driver or capacitor burnout) repair in 24-36 hours. Complex faults requiring DAC recalibration or firmware reprogramming take 48-72 hours. We provide upfront quotes after component diagnosis and allow you to authorize repair before work begins.
Do you recalibrate Microtrol drivers after repair, and is there a warranty?+
Yes. Every repaired Microtrol drive undergoes full recalibration against factory parameters: current limiting, microstepping linearity, timing accuracy, and thermal shutdown thresholds. We bench-test under simulated load and provide a 12-month warranty on all component replacements and rework. If a failure recurs within warranty, we repair it free of labor charges.
Can Synchronics repair Microtrol MCM servo controllers used in packaging machinery?+
Yes. Our engineers specialize in Microtrol MCM-series closed-loop controllers used in food packaging, textile finishing, and automotive assembly lines. We rebuild resolver signal conditioning circuits, recalibrate feedback offsets, reprogram ramp-rate logic, and validate synchronized multi-axis operation. We can also upgrade aging controllers with modern firmware if source code is available.
How do I send my MICROTROL 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 MICROTROL 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 MICROTROL 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 MICROTROL 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.
