AVAT Product Lines We Repair
Our engineers are trained on the full AVAT product range. Below are the major product families we service.
AVAT VFD (Variable Frequency Drive) Series
Single and three-phase VFDs ranging from 0.75kW to 250kW for AC motor speed and torque control. Common faults include capacitor failures, IGBT module shorts, and firmware corruption causing loss of run commands or erratic speed regulation in textile mills and pump stations.
AVAT Soft Starter (Soft Start Controllers)
Three-phase electronic soft starters (22kW to 630kW) for reduced inrush current and mechanical stress on motors and couplings. Typical failures include thyristor gate circuit faults, control transformer burnout, and phase loss detection circuit malfunction affecting cement mill and conveyor systems.
AVAT DC Drive Modules
Thyristor-based and MOSFET DC drive controllers for precision speed and field control in rolling mills, winders, and extruders. Frequent repair issues: rectifier bridge failures, current transformer saturation, armature shunt circuit drift, and control board microprocessor lockup.
AVAT Servo Interface & Encoder Modules
Specialized servo control interfaces and digital encoder input modules for closed-loop motor feedback systems in precision positioning and packaging machinery. Common defects: resolver/encoder connector corrosion, signal conditioning circuit noise, and digital input isolation relay stiction.
AVAT Control & Communication Boards
Embedded control PCBs with Modbus RTU, CANopen, and legacy parallel I/O interfaces for SCADA integration in Indian manufacturing plants. Defects include electrolytic capacitor leakage, optoisolator degradation, crystal oscillator failure, and RS485 transceiver shorts causing communication blackouts.
AVAT Power Supply & Rectifier Modules
Industrial-grade DC and AC power supplies integrated into AVAT control cabinets. Typical failures: filter capacitor bulging, bridge rectifier open junctions, and crowbar overvoltage protection circuit thermal runaway in humid Indian factory environments.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common AVAT Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AVAT equipment arriving at our workshop.
- ✓AVAT VFD capacitor pack bulging and leakage — High ambient temperature (40-50°C common in Indian factories), combined with switching frequency heating of electrolytic capacitors. Moisture ingress through poorly sealed enclosures exacerbates degradation in coastal and monsoon regions.
- ✓AVAT soft starter thyristor gate drive failure — Gate transformer primary-secondary insulation breakdown due to voltage spikes on the main circuit, or failed optoisolator coupling between control and power circuitry. Common in cement plants with poor power quality and frequent load transients.
- ✓AVAT DC drive armature shunt current measurement drift — Precision resistor tolerance shift or sensor module temperature coefficient mismatch over 8-10 years of operation. Rolling mill environments with extreme temperature swings cause analog front-end offset errors.
- ✓AVAT drive display goes blank or shows corrupted characters — LCD connector corrosion, failed display driver IC, or EEPROM checksum error causing display firmware crash. High humidity and salt spray exposure in Indian coastal industrial areas accelerate connector degradation.
- ✓AVAT motor control loss of speed command response (no acceleration) — Encoder feedback circuit open, digital input isolation relay stuck open, or PLC command signal not reaching the drive controller due to cable shielding failure or RS485 termination mismatch on Modbus network.
- ✓AVAT soft starter trips on phase loss during startup — Phase loss detection relay sensitivity set too high, or intermittent line voltage dropout on three-phase supply causing nuisance trips. Indian power grids with frequent phase imbalance trigger false diagnostics.

Frequently Asked Questions — AVAT Repairs
Do you repair AVAT equipment anywhere in India?+
Yes. Synchronics repairs the full AVAT product range — drives, soft starters, DC modules, servo interfaces, and control boards. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all tier-1 and tier-2 cities. All repairs are handled at our main facility in Vadodara, Gujarat, with typical turnaround of 5-7 working days.
What is the typical cost of repairing an AVAT VFD versus replacement?+
AVAT VFD repair costs typically range from 25-40% of new drive purchase price, depending on fault severity. Common repairs like capacitor replacement (Rs. 8,000-15,000) and optoisolator swaps (Rs. 4,000-8,000) are highly cost-effective. Synchronics provides free diagnostic assessment and written repair quotation before work begins, ensuring transparency for plant managers.
Can Synchronics repair AVAT drives with custom firmware or non-standard configurations?+
Yes. Our engineers are proficient in AVAT drive parameter backup, firmware extraction, and safe restoration after component replacement. If original firmware is corrupted, we work with your plant's control system team to re-download factory settings and re-commission custom Modbus or CANopen configurations. We maintain documentation of parameter sets during repair for compliance and future reference.
Do you provide on-site AVAT drive installation and commissioning after repair?+
Yes. For critical textile mills, cement plants, and food processing facilities, Synchronics offers on-site commissioning and load testing after repair. Our field engineers verify motor current, speed stability, and communication handshake before formal sign-off. Travel and per-diem charges apply for locations outside Vadodara; we can coordinate with your plant maintenance team.
What warranty do you provide on AVAT drive repairs?+
Synchronics provides a 12-month warranty on all repaired components and labor, covering manufacturing defects and repair workmanship. This includes replacement of any failed capacitors, relays, or ICs we install during repair. Warranty is void only if the drive is subjected to physical damage, water ingress, or mishandling post-repair. We provide detailed repair report and test results as warranty documentation.
How do I send my AVAT 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 AVAT 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 AVAT 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 AVAT 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.
