ARCAS Product Lines We Repair
Our engineers are trained on the full ARCAS product range. Below are the major product families we service.
ARCAS AC Variable Frequency Drives
Three-phase and single-phase AC drives ranging 0.75 kW to 300 kW for motor speed control in textile mills, cement plants, and packaging lines. Common failures include IGBT thermal cycling, capacitor dry-out, and firmware corruption after power surges.
ARCAS Servo Drive Systems
Closed-loop servo controllers for precision positioning in CNC machines, packaging automation, and test equipment. Repair typically addresses encoder feedback loss, phase commutation errors, and amplifier stage failures.
ARCAS PLC Control Modules
Compact and modular programmable logic controllers with 16 to 256 I/O points for factory automation and process control. Typical issues include memory corruption, real-time clock drift, and relay contact burn-out in high-frequency switching applications.
ARCAS Analog I/O and Sensor Interface Cards
4-20mA input modules, 0-10V output cards, and thermocouple conditioning boards for analog signal acquisition. Failures stem from input overvoltage protection circuit breakdown and DAC linearity degradation.
ARCAS Soft Starter and Motor Protection Units
Electronic soft-starters (22 kW to 200 kW) and integrated thermal overload relays for pump motors and compressors in Indian refineries and cement production. Common defects include phase-angle control thyristor failure and current transformer saturation.
ARCAS Fieldbus and Communication Modules
PROFIBUS DP, MODBUS RTU, and Ethernet gateways for networked factory automation. Repair addresses protocol stack corruption, isolation transformer burnout, and CAN/RS-485 termination resistor failure.

Common ARCAS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ARCAS equipment arriving at our workshop.
- ✓ARCAS drive shows code F-04 voltage regulation fault — Capacitor bank aging or DC bus overvoltage after regenerative load event. ARCAS AC drives use aluminium electrolytic capacitors rated 400V/450V that degrade in high-ambient (50°C+) Indian plant conditions, reducing ESR and allowing bus voltage transients.
- ✓ARCAS servo drive encoder fault — no commutation — Incremental encoder cable shielding break or quadrature decoder IC failure in the servo drive input stage. Indian plant vibration and motor thermal cycling cause connector micro-fractures and IC solder joint fatigue on ARCAS servo modules.
- ✓ARCAS PLC-256 memory error — program checksum invalid — EEPROM cell degradation from power-off transients or prolonged operation in dusty foundries and textile mills. ARCAS modules lack power-fail hold-up in some installations, causing mid-write flash corruption.
- ✓ARCAS analog input card reads erratic 4-20mA signal — Input protection Zener diode shorted by thermocouple ambient temperature rise above 70°C, or common-mode voltage transient from nearby induction motors. ARCAS AIO-16-4-20 modules lack galvanic isolation on some revisions.
- ✓ARCAS soft starter phase imbalance — unequal ramp rates across phases — Gate drive optocoupler aging or thyristor dV/dt snubber capacitor derating in pulsed duty cycles. Indian textile looms operate SS-90 units at 95°C ambient with poor cooling, accelerating component aging.
- ✓ARCAS PROFIBUS module loses network communication after 48 hours runtime — Termination resistor network failure due to reflected signal overvoltage or CAN biasing network capacitor ESR increase. Indian industrial sites with long cable runs (> 100 m) and poor shielding suffer greater PROFIBUS transmission line reflections.

Frequently Asked Questions — ARCAS Repairs
Do you repair ARCAS equipment anywhere in India?+
Yes. Synchronics repairs the full ARCAS product range — AC variable frequency drives, servo motors controllers, PLC modules, analog I/O cards, soft starters, and fieldbus gateways. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Pune, Bangalore, and all other metros. Single repair facility in Vadodara, Gujarat with 48-hour standard turnaround.
What is the typical lead time to repair my ARCAS AV-5500 AC drive?+
ARCAS AV-5500 drives typically enter diagnostics within 8 hours of arrival at Synchronics Vadodara. Capacitor replacement jobs (common in Indian summer climates) take 24-36 hours. IGBT or firmware recovery repairs require 48-72 hours including firmware reburn and load testing. We offer express 24-hour turnaround on premium contract.
Can Synchronics repair ARCAS servo drives with custom encoder offsets or calibration data loss?+
Absolutely. ARCAS servo drives store encoder phase calibration and commutation offset in non-volatile memory. If lost, we can recover from backup files if you have them, or re-perform factory calibration using our servo test bench with adjustable inertia loads. We recommend keeping firmware backups and encoder calibration files offsite for rapid recovery.
My ARCAS PLC-256 module shows memory checksum errors. Can you recover my program code?+
ARCAS PLC flash EEPROM corruption is often recoverable if damage is limited to specific sectors. Synchronics uses specialized ISP tools to extract intact program regions, rebuild missing sections if we have backup, or reconstruct from machine behavior logs. If total code loss occurs, we assist in re-downloading from your source or backup. Always maintain exported program backups outside the module.
Is warranty offered on ARCAS drive repairs, and what does it cover?+
Synchronics provides 12-month warranty on all ARCAS drive repairs covering parts and labor for recurring faults from same root cause. Warranty excludes damage from customer overvoltage, improper cooling, or modified firmware. We issue detailed repair certificates with component-level diagnostics and calibration reports for plant compliance records.
How do I send my ARCAS 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 ARCAS 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 ARCAS 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 ARCAS 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.
