Expert CONTROLPRO control system repair across all product families and fault codes.
CONTROLPRO Product Lines We Repair
Our engineers are trained on the full CONTROLPRO product range. Below are the major product families we service.
CONTROLPRO Drive Controllers
Modular AC and DC drive control units for motors and pump systems. Common issues include capacitor degradation, thyristor failures, and firmware corruption leading to over-current shutdown and reference signal loss.
CONTROLPRO PLC Processors
Compact and modular programmable logic controllers for discrete and process automation. Faults include memory corruption, I/O card failures, and communication bus errors affecting network connectivity.
CONTROLPRO HMI Terminals
Industrial touchscreen and text-based operator interfaces for real-time process monitoring. Repair typically involves display panel replacement, communication daughterboard failure, and kernel crashes causing unresponsive screens.
CONTROLPRO Servo Amplifiers
High-precision feedback amplifiers for stepper and brushless DC motors in positioning and speed control. Common failures are position encoder signal loss, PWM output stage failure, and overtemperature sensor malfunction.
CONTROLPRO Industrial I/O Modules
Distributed input/output terminals for sensor and actuator integration. Typical faults include optocoupler degradation, relay contact welding, analog isolation failures, and data transmission errors on industrial networks.
CONTROLPRO Communication Interfaces
Ethernet, Modbus, CANopen, and Profibus gateway modules for plant-wide integration. Faults include connector corrosion, firmware version incompatibility, protocol parsing errors, and network isolation breakdown.

Common CONTROLPRO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTROLPRO equipment arriving at our workshop.
- ✓Drive controller capacitor failure and voltage regulation — Electrolytic capacitors in CONTROLPRO DC bus circuits degrade due to heat cycling and industrial ambient humidity. This causes ripple voltage to rise, reducing drive stability and triggering over-voltage shutdown codes E-OVP or E-CAP.
- ✓PLC memory corruption and program loss — CONTROLPRO PLC battery backup failure or power supply glitches cause volatile memory (RAM) contents to corrupt. User program becomes unreadable, resulting in E-MEM or checksum error messages on boot.
- ✓HMI display panel dead or partial pixel failure — CONTROLPRO touchscreen displays suffer backlight LED aging, inverter board shorts, or LCD panel delamination from thermal stress and moisture ingress common in Indian mill and pharmaceutical environments.
- ✓Servo feedback encoder signal loss and position error — CONTROLPRO servo amplifiers lose encoder feedback due to corroded connectors, broken cable shielding, or internal encoder optocoupler failure. The drive reports E-ENC or E-COMM errors and halts all motion.
- ✓I/O module optocoupler and relay contact degradation — CONTROLPRO distributed I/O terminals experience optocoupler LED aging and relay armature stiction from vibration and high-cycle switching. Output channels become intermittent or non-responsive.
- ✓Communication gateway firmware version mismatch and timeout — CONTROLPRO Ethernet and Modbus gateways lose network heartbeat if firmware is outdated or incompatible with plant network switches. Industrial switches drop packets from unknown MAC addresses, causing E-NET or E-LINK codes.

Frequently Asked Questions — CONTROLPRO Repairs
Do you repair CONTROLPRO equipment across India?+
Yes. Synchronics is India's trusted CONTROLPRO repair partner. We repair all CONTROLPRO product families — drive controllers, PLCs, HMI terminals, servo amplifiers, I/O modules, and communication gateways — from our Vadodara facility. We offer free PAN India pickup from Mumbai, Delhi, Pune, Bangalore, Hyderabad, Chennai, Ahmedabad, and all other major cities. Typical turnaround is 3-7 working days depending on fault complexity.
What CONTROLPRO error codes does Synchronics diagnose and repair?+
We diagnose and repair all standard CONTROLPRO fault codes including E-OVP (over-voltage), E-CAP (capacitor), E-MEM (memory), E-ENC (encoder), E-NET (network), E-LINK (communication), E-TEMP (overtemperature), and E-PHASE (phase loss). Our engineers use CONTROLPRO diagnostic tools and oscilloscopes to isolate root causes and verify repairs with functional testing before dispatch.
How does Synchronics test CONTROLPRO equipment after repair?+
Every repaired CONTROLPRO unit undergoes comprehensive functional testing on our industrial test benches. Drive controllers are load-tested under rated current; PLCs are programmed with diagnostic routines; HMIs are checked for display and touch response; servo amplifiers are verified on feedback loops; and communication gateways are tested with live Ethernet and industrial protocol traffic. Full test certificates are provided with every repair.
Can Synchronics repair CONTROLPRO equipment from small textile mills and startups?+
Absolutely. Synchronics serves small to large Indian manufacturers. We understand that downtime costs money for every business size. Our repair pricing is transparent and competitive. We repair individual CONTROLPRO modules as well as complete control cabinets. Free diagnostic reports and upfront quotations are provided before work begins.
Do you offer spare parts for CONTROLPRO equipment?+
Yes. Synchronics stocks common CONTROLPRO replacement components including capacitor kits, optocoupler arrays, relay modules, encoder connectors, and daughter boards. We source genuine CONTROLPRO spares and equivalent components from certified suppliers. If a part is not in stock, we source it within 2-3 working days. Contact our sales team for spare parts pricing and availability.
How do I send my CONTROLPRO 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 CONTROLPRO 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 CONTROLPRO 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 CONTROLPRO 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.
