AMC Product Lines We Repair
Our engineers are trained on the full AMC product range. Below are the major product families we service.
AMC BiMD Series (Brushless Integrated Motor Drives)
Compact brushless servo drive modules combining motor controller, power amplifier, and safety logic in single units. Common issues include commutation sensor failures, phase winding shorts, and firmware corruption causing encoder signal loss or position sync errors.
AMC Tri-Mode Stepper Drivers
Microstepping motor drivers supporting PWM, sign-magnitude, and pulse-direction control modes. Failures typically manifest as step loss, thermal shutdown, intermittent axis movement, and gate driver transistor burnout under load spikes.
AMC Digital DC Drive Modules (DDM Series)
Programmable DC motor drives with regenerative braking and field-weakening capabilities. Common faults include Hall effect sensor degradation, PWM filter capacitor ripple, and analog feedback scaling drift causing speed regulation errors.
AMC CANopen Motion Controllers
Networked motion control nodes with integrated CANbus interfaces for multi-axis synchronized systems. Repair complexity arises from CANbus termination faults, CiA 402 protocol stack corruption, and isolated 24V power supply failures.
AMC Encoder Interface Modules (EIM)
Incremental and absolute encoder signal conditioning units used in feedback loops. Typical failures: differential signal termination open circuits, ESD damage on encoder input ports, and clock synchronization loss causing jitter in servo feedback.
Why Choose Synchronics for AMC Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on AMC equipment.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common AMC Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AMC equipment arriving at our workshop.
- ✓BiMD commutation sensor failure - no motor commutation — Hall effect sensor pins corroded due to moisture ingress or sensor magnet demagnetized after thermal stress. AMC BiMD drives require proper sensor gap (1-2mm) and magnetic field stability.
- ✓Stepper driver microstepping error - intermittent axis movement — AMC Tri-Mode drivers experience current ripple in microstepping modes when PWM frequency drifts or phase current sense resistors develop resistance creep. Causes timing skew between phase PWM signals.
- ✓DDM regenerative braking capacitor failure - overvoltage shutdown — Braking resistor thermal sensor opens or fails to trigger. Regenerative energy from motor deceleration overwhelms DC bus capacitors, exceeding 60V threshold in 48V AMC DDM modules, triggering firmware overvoltage cutoff.
- ✓CANopen node no longer visible on network - CAN bus isolation — AMC CANopen controller isolated 24V supply capacitor fails (dry joint or dielectric breakdown), preventing node from pulling idle CAN bus pullup resistors to proper bias voltage. Node transmits but cannot receive.
- ✓Encoder feedback signal jitter causing servo instability — AMC EIM interface modules experience common-mode noise coupling onto differential encoder signals due to damaged shielded twisted-pair cables or missing ferrite termination. Signal noise amplitude exceeds encoder pulse edge timing tolerance.
- ✓Firmware checksum mismatch - drive non-responsive — Power loss during firmware upload or flash memory bit-flip caused by ESD event. AMC drive bootloader detects corrupted application code and enters safe state, requiring factory firmware reload.

Frequently Asked Questions — AMC Repairs
Do you repair AMC equipment anywhere in India?+
Yes. Synchronics repairs the full AMC product range — BiMD brushless drives, Tri-Mode stepper drivers, DDM DC drive modules, CANopen motion controllers, and encoder interface modules. We offer PAN India door-step pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all major industrial cities. All repairs serviced at our 14,000 sq ft facility in Vadodara, Gujarat with 48-72 hour turnaround for standard faults.
Can you repair AMC BiMD drives with corrupted firmware or lost parameter backup?+
Absolutely. Synchronics holds OEM factory authorization to reload AMC BiMD firmware from verified source code archives. If your parameter backup is unavailable, our engineers reverse-engineer the application by analyzing motor specifications, load characteristics, and control loop behavior from your machine documentation. We reprogram commutation offset, current limits, and encoder resolution to match your original settings, then validate with live motor testing under load.
What warranty and certification does Synchronics provide for AMC drive repairs?+
All repaired AMC equipment receives a 12-month comprehensive warranty covering parts and labor, with option to extend to 24 or 36 months for critical production systems. Equipment is returned with ISO-certified test reports documenting initial fault diagnosis, repair actions, component replacements, and final validation test results. Statutory GST invoices and NASSCOM-compliant service documentation provided for all work.
How long does repair typically take for an AMC Tri-Mode stepper driver with microstepping faults?+
Standard turnaround is 3-5 business days in-house. Diagnosis typically requires 4-6 hours on our test bench, with microstepping verification taking 8-12 hours due to high-resolution current waveform capture and linearity analysis across all 256 microstep settings. Urgent same-day turnaround available for documented production emergencies, subject to component availability. Express courier returns arranged within 24 hours of completion.
Do you stock genuine AMC spare components for repair, or use aftermarket equivalents?+
Synchronics stocks OEM-authorized AMC components including Hall effect sensor modules, power MOSFET arrays, encoder interface chipsets, and control logic firmware. For passive components (capacitors, resistors, connectors), we source military-grade equivalents from Vishay, Panasonic, and Amphenol meeting or exceeding original specifications. All component sourcing documented on repair certificates. Customers requiring 100% OEM parts can request OEM-matched ordering; we support direct purchase through our AMC distributor network.
How do I send my AMC 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 AMC 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 AMC 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 AMC 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.
