AMI Product Lines We Repair
Our engineers are trained on the full AMI product range. Below are the major product families we service.
AMI Stepper Motor Drivers
Microstepping driver modules for NEMA 17, 23, 34 stepper motors with advanced current control. Common failures include phase open-circuit faults, chopper frequency instability, and logic board heat damage from inadequate cooling in dusty mill environments.
AMI Servo Drive Systems
Closed-loop servo amplifiers for brushless and brushed servo motors with analog and digital command inputs. Typical repair issues include encoder signal loss, servo fault codes (E06, E07, E13), and capacitor bank degradation in high-vibration textile machinery.
AMI Motion Control Modules
Standalone motion controllers with RS485, Ethernet, and analog I/O for multi-axis coordination. Failures include firmware corruption, communication timeouts, and analog input channel faults common in retrofit scenarios on older Indian manufacturing lines.
AMI Stepper Motor Assemblies
Integrated stepper motors with integrated connectors for packaging machinery, textile looms, and printing press drive systems. Common issues: winding insulation breakdown due to moisture in coastal Indian plants, bearing wear in high-duty-cycle applications, and rotor demagnetization.
AMI Encoder and Feedback Modules
Incremental and absolute encoders compatible with AMI servo drives and motion controllers. Repair needs include connector oxidation, LED aging (affecting optical sensing), and cable shield damage in high EMI industrial environments common in Indian foundries and stamping plants.
AMI Power Supply Modules
24VDC regulated supplies and step-down modules for stepper driver logic circuits. Frequent failures in Indian industrial settings: blown rectifier bridges from voltage spikes, electrolytic capacitor venting from inadequate ventilation in machinery cabinets, and thermal fuse nuisance trips.

Common AMI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AMI equipment arriving at our workshop.
- ✓Stepper driver phase open-circuit or missing phase — Connector pin oxidation or intermittent wiring in motor cable, exacerbated by humidity in coastal Indian textile mills. Power transistor gate drive failure leaves one phase non-functional, causing loss of torque and audible vibration.
- ✓Servo fault code E06 or E07 encoder loss — Encoder cable shield damage or shear in high-motion packaging line environments. Optical encoder LED degradation after 10,000+ hours of operation reduces reflective signal, causing intermittent encoder loss during high-speed acceleration.
- ✓Electrolytic capacitor venting or bulging — Inadequate cooling in machinery electrical cabinets common in Indian foundries; stepper drivers generate 5-10W heat per axis. Sustained 65-70 degree Celsius environment degrades capacitor electrolyte, causing internal pressure buildup and eventual failure.
- ✓Motion jitter, stalling, or lost steps during operation — Microstepping current imbalance in AMI driver caused by component drift or incorrect calibration after previous repair. Load inertia mismatch or mechanical binding in coupled machinery also triggers erratic motion visible in printing or textile applications.
- ✓No communication or intermittent RS485 dropout — Common in retrofit Indian textile mills: unshielded RS485 cables run parallel to high-current AC lines, inducing noise. Termination resistors missing or incorrect at network ends cause signal reflections; corrupted firmware may lock communication port.
- ✓Logic board power-on failure or no status LED indication — Rectifier bridge failure from input transient spikes during generator-backed power loss in Indian plants subject to voltage fluctuations. Blown fuses or gate drive IC failure prevents logic supply voltage reaching microcontroller, rendering entire AMI module non-functional.

Frequently Asked Questions — AMI Repairs
Do you repair AMI equipment anywhere in India?+
Yes. Synchronics repairs all AMI motion control products — stepper drivers, servo amplifiers, motion controllers, and integrated motor assemblies — across India. We offer door-to-door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other Indian cities. All repairs processed at our 7,000 sq ft facility in Vadodara, Gujarat with 24-hour turnaround on standard repairs.
What is the typical turnaround time for AMI stepper driver repair?+
Standard AMI stepper driver repairs (phase testing, current recalibration, capacitor replacement) are completed within 24 hours after arrival at Synchronics Vadodara facility. Servo drive repairs with encoder diagnostics typically require 2-3 days. Firmware reprogramming adds 1-2 days if source files are unavailable. Emergency same-day service available for production-critical equipment; contact our dispatch team.
Can Synchronics repair AMI stepper motors that are integrated with gearboxes?+
Yes. We service integrated AMI stepper-gearbox assemblies including planetary and helical reductors. Repair scope includes motor winding testing, rotor assessment, bearing condition evaluation, and gearbox oil analysis. However, if gearbox damage is severe (stripped helical gears, bearing seizure), we advise motor replacement with new AMI assembly. We maintain relationship with local Indian stepper motor manufacturers for cost-effective replacement options.
Do you stock spare AMI components and can they be shipped separately?+
Synchronics maintains rotating stock of high-failure AMI components: stepper driver MOSFETs, servo encoder modules, 24VDC power supply units, and microstepping current trim potentiometers. Components are available for individual purchase and shipped same-day to Indian addresses. For critical production spares, we recommend advance bulk orders (minimum 5 units) for better lead times and pricing.
How do I check if my AMI equipment is repairable versus requiring replacement?+
Contact Synchronics for free fault diagnosis. Send photos/descriptions of error codes or symptoms, and our engineers will provide rapid assessment. Most AMI failures are economically repairable — stepper drivers cost Rs 8,000-15,000 new versus Rs 3,000-5,000 repair; servo modules repair cost 40-50% of replacement. We email detailed cost quotes before proceeding with repair.
How do I send my AMI 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 AMI 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 AMI 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 AMI 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.
