AAI Product Lines We Repair
Our engineers are trained on the full AAI product range. Below are the major product families we service.
AAI Servo Drive Controllers
Precision servo drive systems for multi-axis motion control. Common issues include encoder disconnection, torque limiting faults, phase loss errors, and firmware corruption affecting closed-loop stability and acceleration ramps.
AAI Motion Controllers & PLCs
Real-time programmable logic controllers with integrated motion profiles. Typical faults include communication module failure, I/O card burnout, battery-backed RAM corruption, and scan time violations causing synchronization loss.
AAI Stepper & Stepper Driver Cards
Stepper motor drivers and microstepping controllers for precision positioning. Failure modes include coil resistance drift, H-bridge transistor burnout, step-direction interface faults, and thermal shutdown due to inadequate heatsinking.
AAI Analog & Digital Interface Modules
I/O expansion cards, analog input/output boards, and fieldbus gateway modules. Common defects include op-amp failures, ADC/DAC calibration drift, relay contact welding, and EtherCAT/CANopen communication stack breakdown.
AAI Encoder & Feedback Interface Boards
Incremental and absolute encoder signal conditioning, resolver interfaces, and SSI decoder modules. Repair challenges include signal noise immunity, commutation timing errors, zero-position loss, and multi-turn absolute encoder initialization failure.
AAI Safety & Emergency Stop Modules
Certified safety-rated emergency stop controllers and safe motion disable logic. Typical faults include safety relay chatter, dual-channel diagnostic loop failure, enabling device debounce timing errors, and SIL rating invalidation.

Common AAI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AAI equipment arriving at our workshop.
- ✓AAI servo encoder signal loss or intermittent dropout — Incremental encoder cable shield degradation, broken differential pair wires, or failed encoder feedback conditioning circuitry causes the servo drive to lose position feedback. This triggers E-STOP or uncommanded deceleration, halting synchronized multi-axis motion.
- ✓AAI drive shows Phase Loss or Voltage Fault at startup — Single-phase input loss, blown DC bus capacitors, or failed three-phase rectifier bridge in the servo drive power supply. AAI firmware detects rail imbalance and prevents motor energization to avoid coil damage.
- ✓AAI stepper driver produces jerky motion or step loss — Microstepping coil resistance drift, H-bridge MOSFET saturation voltage rise, or inadequate peak current causes motor detent torque to fall below load requirements. Current sense resistor aging or degraded thermal paste also reduces stepper holding force.
- ✓AAI motion controller scan time violation or Task Cycle Exceed error — Overloaded PLC logic, corrupted interrupt handler code, background communication traffic from Ethernet or serial port, or real-time clock oscillator drift. Motion synchronization algorithms fail when scan period exceeds worst-case latency budget.
- ✓AAI absolute encoder multi-turn counter reset or zero-position loss — Battery backup failure in multi-turn encoder interface board prevents preservation of power-loss turn count. Backup capacitor dry-out, diode leakage, or failed battery charging circuit causes position data corruption during downtime or power-cycle events.
- ✓AAI EtherCAT or CANopen gateway communication timeout or slave device dropout — Corrupted fieldbus stack firmware, failed network transceiver IC (isolation optocoupler or CAN PHY), or timing synchronization loss between master and distributed I/O nodes. Packet collision or CRC errors corrupt motion commands, halting synchronized axes.

Frequently Asked Questions — AAI Repairs
Do you repair AAI equipment anywhere in India?+
Yes. Synchronics repairs the full AAI product range — servo drives, motion controllers, stepper drivers, encoder interfaces, and safety modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other major cities. All repairs are performed at our 25,000 sq ft facility in Vadodara, Gujarat, with same-day receipt turnaround and 7-14 day average repair completion.
What is the typical repair turnaround for AAI servo drives at Synchronics?+
Standard turnaround is 7-10 working days from receipt. For critical production situations, Synchronics offers express diagnostics (24 hours) and expedited repair (3-5 days) at a premium rate. We provide loaner drives and modular swaps to minimize your downtime while your unit is being rebuilt and burn-tested.
Can Synchronics repair AAI multi-axis motion controllers with corrupted firmware?+
Yes. Synchronics extracts AAI controller firmware from backup images maintained in our technical library, or recovers code from your commissioning documentation. If firmware is missing, we can often rebuild critical motion profiles from installed parameter copies. We test all restored logic on simulation hardware before returning equipment to production.
Do you offer AAI encoder calibration and commissioning after repair?+
Yes. Synchronics provides full encoder signal path re-calibration including differential signal symmetry, zero-position alignment, and multi-turn turn-count synchronization. We use precision test fixtures and document all calibration values. Customers receive a full commissioning report with before/after encoder linearity plots and repeatability data.
What warranty does Synchronics provide on repaired AAI equipment?+
All repaired AAI equipment carries a 12-month comprehensive parts and labour warranty covering defects introduced during repair. We also offer extended coverage (24 months) on critical servo drives and motion controllers. If equipment fails in service within warranty, we provide free re-repair or replacement at our discretion.
How do I send my AAI 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 AAI 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 AAI 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 AAI 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.
