AM Product Lines We Repair
Our engineers are trained on the full AM product range. Below are the major product families we service.
AM Stepper Motor Controllers
Precision stepper drive modules used in CNC mills, lathes, and textile machinery. Common issues include power stage failures, encoder interface faults, and control signal loss due to electrical surge or thermal stress in high-vibration environments.
AM Servo Amplifiers
High-bandwidth servo drives for closed-loop motion control in automation equipment. Repair focuses on gate driver failures, capacitor degradation, and servo feedback circuit malfunctions causing position loss or oscillation errors.
AM Motion Control Boards
Embedded motion control processors and PWM driver boards for OEM machinery integration. Typical faults include firmware corruption, EEPROM programming errors, and digital I/O module shorts affecting machine sequencing.
AM Encoder Interface Modules
Quadrature and SSI encoder signal conditioning boards for position feedback systems. Common failures involve connector oxidation, buffer IC degradation, and differential signal loss in high-EMI factory environments.
AM Spindle Drive Units
Specialised AC spindle motor controllers for machine tool spindles in Indian CNC shops. Prone to thermal runaway, capacitor bulging, and field weakening circuit faults under continuous high-speed operation.
Why Choose Synchronics for AM 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 AM equipment.
Fast Turnaround
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 AM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AM equipment arriving at our workshop.
- ✓AM servo drive gate driver failure — Repeated thermal cycling and high gate charge current in Indian factory climates with poor cooling cause IGBT driver IC degradation, resulting in gate voltage loss and servo unresponsiveness. Moisture ingress in humid coastal regions accelerates this.
- ✓AM stepper controller encoder signal loss — Encoder connector corrosion and vibration-induced micro-fractures in differential signal traces are common in Indian textile mills and foundries where humidity and mechanical shock are constant. Cable shielding degradation allows EMI coupling.
- ✓AM motion control board EEPROM corruption — Power supply transients, voltage spikes from adjacent welding equipment, and brownouts common in Indian industrial zones corrupt flash memory, causing the drive to lose calibration or enter safe state. Unfiltered mains supply is a major culprit.
- ✓AM spindle drive capacitor bulging and leakage — Electrolytic capacitor degradation under thermal stress in continuous 24/7 spindle operation, combined with high ripple current from PWM switching and inadequate cooling, is endemic in Indian CNC shops. Bus capacitors fail within 2-4 years.
- ✓AM servo amplifier output stage short-to-ground — Phase output transistor gate oxide breakdown occurs after insulation failure in motor cables or when servo motors are operated beyond thermal limits. Indian manufacturing plants often over-stress servo motors in precision grinding and CNC applications.
- ✓AM stepper drive microcontroller reset loop — Watchdog timer resets caused by firmware stack overflow, interrupt handler conflicts, or corrupted program memory from ESD strikes on unprotected I/O ports. Indian facilities with high static discharge risk see this frequently.

Frequently Asked Questions — AM Repairs
Do you repair AM equipment anywhere in India?+
Yes. Synchronics repairs the complete AM servo drive and motion control electronics portfolio. We offer PAN-India door pickup from all major metros — Mumbai, Delhi, Pune, Bengaluru, Chennai, Hyderabad, Ahmedabad, Jaipur, and tier-2 cities. All repairs are handled at our 180-engineer facility in Vadodara, Gujarat. We maintain rapid turnaround to get your CNC machines and textile looms back online quickly.
What is the typical repair turnaround for AM servo drives in India?+
For standard AM servo amplifier and motion controller faults, Synchronics delivers 7-10 working days from inward inspection to test certification and dispatch. Critical faults requiring microcontroller reprogramming or custom calibration may take 12-15 days. We prioritise high-downtime equipment and offer express repair with Saturday-Sunday turnaround for premium clients. Logistics (pickup and delivery) adds 2-3 days depending on your location.
Can you repair AM stepper motor controllers if I do not have the original documentation?+
Absolutely. Synchronics maintains reverse-engineered schematics and firmware dumps for all major AM stepper controller models (AM2020, AM3030, AM4040 series). Our technicians perform full functional testing without original manuals using logic analysers and oscilloscope signal capture. We can also extract your motor tuning parameters and re-load them after repair, ensuring your CNC machine or textile loom performs identically post-repair.
Do you stock spare parts for AM motion control electronics?+
Yes. Synchronics maintains high-stock inventory of AM replacement modules including servo amplifier output stages, stepper driver power boards, encoder interface modules, and microcontroller units. We also stock replacement capacitors, gate driver ICs, and power MOSFETs for AM equipment. If a part is non-stock, we source globally within 5-7 days. All spares come with full warranty and are tested before installation.
Can Synchronics help if my AM drive shows a fault code I cannot interpret?+
Yes. Our 180+ engineers are fluent in AM fault code diagnostics across all product lines. We maintain digital fault code libraries for AM stepper controllers, servo drives, and spindle controllers. Simply send us a photo of the display error or provide the fault code number, and we will advise on repair approach, likely root cause, and estimated repair cost. Many faults can be resolved via firmware updates or parameter resets, saving you repair expense.
How do I send my AM 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 AM 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 AM 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 AM 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.
