Arestech Equipment We Repair — By Category
Arestech Product Lines We Repair
Our engineers are trained on the full Arestech product range. Below are the major product families we service.
ARESTECH Eco-VFD Series
Variable frequency drives ranging 1 kW to 450 kW designed for energy-efficient motor control in Indian industrial plants. Common issues include capacitor failure under high ambient temperatures, firmware crashes, and loss of communication in multi-drive networked setups.
ARESTECH Smart Soft Starters
Electronic soft starters for AC motors 3 kW to 250 kW, reducing inrush current and mechanical stress. Repair focus: thyristor module degradation, analog control card faults, and thermal sensor malfunctions in dusty mill environments.
ARESTECH Compact PLC Controllers
Modular programmable logic controllers for local control, data logging, and SCADA integration on shop floors. Typical failures: input/output relay card burnout, memory buffer overflow, and RS485 communication module short circuits.
ARESTECH Panel Mount HMI Displays
7-inch and 10-inch touchscreen human-machine interfaces for real-time process monitoring in cement kilns, sugar mills, and textile looms. Common issues: LCD backlight failure, touchscreen calibration drift, and firmware version incompatibility with legacy drivers.
ARESTECH Power Factor Correction Modules
Automatic capacitor bank switching units for harmonics mitigation and power factor improvement, essential for compliance with Indian grid regulations. Repair challenges: contactor coil burnout, capacitor bank degradation, and microcontroller firmware corruption.

Common Arestech Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in Arestech equipment arriving at our workshop.
- ✓Arestech VFD display shows E-06 fault code — E-06 indicates internal IGBT over-current or phase loss detection. This occurs when motor load spikes suddenly, ambient temperature exceeds 50°C in unventilated panels, or when DC bus capacitors age and lose capacitance below design specification.
- ✓Arestech Eco-VFD loses RS485 communication intermittently — Communication card isolation transformer or opto-coupler degradation is common in humid Indian climates. Industrial noise coupling through unshielded cable runs and missing ferrite terminators on long runs cause signal reflections and frame corruption.
- ✓Arestech Soft Starter thyristor module shows gate drive failure — Thermal cycling in non-air-conditioned mill environments causes solder micro-cracks in the gate drive optocoupler. Inadequate heatsink contact or dust accumulation reduces heat dissipation, thermally stressing the gate drive IC.
- ✓Arestech HMI touchscreen becomes unresponsive or calibration drifts — High humidity and temperature fluctuation in cement kiln control rooms cause capacitive touchscreen controller ICs to drift out of specification. Dust infiltration between LCD and touch layers introduces resistance that degrades signal quality.
- ✓Arestech PLC input/output relays chatter or fail to switch — Relay coil insulation breakdown under high ambient temperatures (55°C+ in Indian summer), contact welding due to inductive transient overvoltage when motor loads switch off, or carbon contamination on relay contacts in textile spinning units.
- ✓Arestech PFC module contactor coil burns out repeatedly — Repeated capacitor bank switching induces high inrush current that stresses the contactor coil electromagnet. Inadequate suppression diodes or missing varistor protection allows voltage transients to degrade coil insulation over time.

Frequently Asked Questions — Arestech Repairs
Do you repair Arestech equipment anywhere in India?+
Yes. Synchronics repairs the complete Arestech product range — VFDs, soft starters, PLCs, HMI touchscreens, and power factor correction modules. We offer PAN India door pickup from Mumbai, Delhi, Pune, Hyderabad, Chennai, Ahmedabad, Bangalore, and all tier-2 cities. All repairs are performed at our factory facility in Vadodara, Gujarat, with turnaround typically 5-7 working days.
What is the average repair turnaround time for an Arestech VFD with E-06 fault?+
Arestech E-06 faults (IGBT over-current) require component-level diagnosis and IGBT module replacement, typically 7-10 working days. If the fault is due to firmware corruption alone, Synchronics can reprogram within 2-3 days. We provide daily status updates and expedited service for emergency breakdowns affecting production.
Does Synchronics stock Arestech spare parts or IGBT modules?+
Yes. Synchronics maintains inventory of Arestech IGBT modules, capacitor banks, optocoupler ICs, relay modules, and firmware for common VFD and PLC models. We source original Arestech components through authorized distribution partners and maintain quality traceability. For non-stock items, we procure directly from Arestech Bangalore within 3-4 working days.
Can Synchronics repair Arestech equipment that is out of warranty?+
Absolutely. Synchronics specializes in out-of-warranty Arestech repair across all vintage models — even equipment 10-15 years old running in sugar mills and textile plants. We perform full diagnostic analysis, component replacement, and firmware updates regardless of warranty status. Repair pricing is transparent and often more cost-effective than replacement.
Do you provide on-site installation or commissioning support for repaired Arestech drives?+
Yes. After repair, Synchronics offers on-site commissioning support across India for complex Arestech VFD and PLC installations. Our field engineers carry load-testing equipment, communication analyzers, and power quality meters to verify safe operation at your plant. Optional preventive maintenance contracts are available for high-criticality equipment.
How do I send my Arestech 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 Arestech 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 Arestech 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 Arestech 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.
