AMCI Product Lines We Repair
Our engineers are trained on the full AMCI product range. Below are the major product families we service.
AMCI Stepper Drive Controllers
Microstepping and full-step stepper motor drive modules with integrated encoder feedback. Common repair issues include loss of microstep resolution, phase winding short-circuits, logic board failures under thermal stress, and encoder signal interface faults in high-vibration environments.
AMCI Servo Drive Amplifiers
Closed-loop servo amplifiers with encoder-based commutation feedback for brushless DC motors. Typical failures include commutation loss on power-up, encoder interface disconnection, FET bridge thermal runaway, and velocity loop instability under load transients.
AMCI Absolute Position Encoders
Single-turn and multi-turn absolute encoders (SSI, CANopen, Modbus protocols) used in printing, packaging, and textile machinery. Repair challenges include bearing wear causing eccentric output, magnet demagnetization, and protocol communication timeouts after power surge events.
AMCI Incremental Encoders
High-resolution incremental encoders for rotary position feedback in CNC machines, winding equipment, and film converting lines. Common defects: phototransistor degradation in humid environments, quad counter chip failures, and connector corrosion in coolant-exposed applications.
AMCI Motion Controller Modules
Compact motion control modules combining stepper/servo drive logic, encoder interface, and communication modules (RS-232, CANopen, Ethernet) for standalone or OEM integration. Repair involves FPGA re-flashing, communication stack debugging, and power supply regulation restoration.
AMCI Power Supply and Interface Cards
Regulated DC supplies and signal conditioning cards for stepper/servo systems. Failure modes include capacitor dry-out, voltage regulation IC thermal breakdown, optical isolation chip failure in noisy industrial environments, and PCB trace corrosion.

Common AMCI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AMCI equipment arriving at our workshop.
- ✓Encoder signal loss or intermittent dropout — AMCI encoders in textile mills and printing presses experience intermittent signal loss due to vibration-induced connector loosening, capacitive coupling noise from adjacent power cables, or bearing wear causing radial runout that exceeds optical sensor threshold.
- ✓Stepper motor phase winding short-circuit — AMCI stepper drive modules operate unprotected in environments with water spray (pharma, food processing). Moisture ingress or thermal cycling causes phase winding insulation breakdown, typically between adjacent poles or to ground frame.
- ✓Commutation failure on servo drive startup — AMCI brushless servo drives (BLY series) fail to commutate if encoder alignment is lost during power-down or if the commutation offset table is corrupted. This is common after power surges or manual encoder re-positioning without controller reset.
- ✓Motion controller communication timeout (CANopen, SSI, Modbus) — Industrial EMI from induction furnaces, arc welders, or motor starters in heavy manufacturing (steel mills, foundries) corrupts serial frames in AMCI motion controllers, triggering protocol error flags and loss of encoder data transmission.
- ✓Power stage FET thermal runaway — AMCI stepper and servo drive MOSFETs overheat when motor load spikes exceed controller current limit, or when cooling fan blockage prevents adequate heat dissipation in cramped panel installations (common in Indian automotive assembly plants).
- ✓Absolute encoder protocol error or invalid position output — AMCI single-turn or multi-turn absolute encoders lose calibration after mechanical shock (drop, vibration impact during transport) or battery failure in multi-turn models. CANopen/SSI communication frames become malformed if internal PLD code is corrupted.

Frequently Asked Questions — AMCI Repairs
Do you repair AMCI equipment anywhere in India?+
Yes. Synchronics repairs the complete AMCI product range — stepper drives, servo amplifiers, absolute and incremental encoders, motion controllers, and power supplies. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and all other industrial cities. All repairs are performed at our 180-engineer facility in Vadodara, Gujarat, with same-day bench diagnostics and 7-10 day turnaround.
What is the cost and turnaround time for AMCI stepper drive repair?+
AMCI stepper drive repairs (M17, M23, M34, CPM-2 series) typically cost INR 4,500 - 8,000 depending on fault severity. Bench diagnostics are completed within 24 hours; full repair including component replacement and testing takes 5-7 working days. Synchronics offers prepaid courier pickup from your plant and return shipping as part of the service package.
Can you repair AMCI servo drives with encoder feedback systems?+
Yes, absolutely. Synchronics specialises in AMCI BLY series servo amplifiers (BLY172T, BLY341, BLY573) with integrated encoder commutation. We diagnose commutation faults, encoder signal interface issues, power stage failures, and velocity loop instability. We maintain encoder test fixtures for phase alignment validation and replace any damaged optical or magnetic sensors. Full re-commissioning including firmware re-flash is included.
How do you handle AMCI absolute encoder multi-turn battery replacement?+
AMCI multi-turn absolute encoders (11A20606, 11AR20401) use internal lithium batteries for turn-count retention. Synchronics replaces expired batteries, recalibrates the absolute position lookup table, and verifies SSI or CANopen protocol output against our reference fixture. Battery replacement typically costs INR 2,000-3,500 including labour.
What certifications and test equipment does Synchronics use for AMCI repairs?+
Synchronics uses ISO 9001-certified processes and maintains AMCI-compatible test benches for stepper/servo encoder calibration, commutation verification, and communication protocol validation (CANopen, SSI, Modbus). We hold spare stock of genuine AMCI components and provide 12-month warranty on all repairs. Our engineers are trained on AMCI product datasheets and application notes.
How do I send my AMCI 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 AMCI 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 AMCI 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 AMCI 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.
