ELECTRO-PRO Product Lines We Repair
Our engineers are trained on the full ELECTRO-PRO product range. Below are the major product families we service.
ELECTRO-PRO Servo Drives (SD-Series)
High-performance servo drive units for precision spindle and axis control in CNC machines, textile machinery, and printing presses. Common failures include resolver/encoder interface faults, PWM bridge failures, and firmware corruption affecting motion accuracy.
ELECTRO-PRO AC Vector Drives (ACV-Range)
Variable frequency drives for AC motor speed control in pumps, compressors, fans, and conveyor systems. Typically fail due to thermal stress on IGBTs, capacitor degradation under Indian ambient conditions, and harmonic distortion from weak grid supplies.
ELECTRO-PRO DC Drive Controllers (DC-Pro)
Regulated DC drive solutions for legacy and high-torque applications in rolling mills, presses, and paper machinery. Susceptible to thyristor short-circuits, field coil insulation breakdown, and control circuit failures under high ambient temperatures.
ELECTRO-PRO Motion Control Modules (MCM-300/500)
Standalone motion controllers with integrated CANopen and Modbus interfaces for multi-axis coordination. Faults include communication interface breakdown, real-time kernel corruption, and calibration loss affecting synchronization.
ELECTRO-PRO Spindle Drive Units (SDU-Industrial)
Specialized drives for high-speed spindle motors in machine tools, grinding centers, and precision boring machines. Prone to bearing current damage, resolver signal loss, and thermal runaway in poorly ventilated enclosures typical of Indian shop floors.

Common ELECTRO-PRO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in ELECTRO-PRO equipment arriving at our workshop.
- ✓IGBT module thermal runaway and short circuit — ELECTRO-PRO servo and AC drives operate under harsh Indian manufacturing environments with ambient temperatures exceeding 45°C. Inadequate heatsink cleaning due to dust and moisture ingress combined with long production runs causes junction temperature to exceed safe limits, leading to IGBT gate-oxide failure and catastrophic short-circuits.
- ✓Resolver or encoder interface signal loss — ELECTRO-PRO servo drives rely on high-resolution position feedback from resolvers or optical encoders. Vibration-induced connector looseness, corroded pins from humidity in coastal Indian plants, and cable shield degradation interrupt feedback, causing fault codes and loss of commutation.
- ✓Capacitor bank degradation and ESR rise — Electrolytic capacitors in ELECTRO-PRO DC link circuits degrade rapidly in high-ambient Indian environments, especially textile mills near exhaust ducts. Rising equivalent series resistance (ESR) reduces filter effectiveness, introduces ripple into control circuits, and eventually triggers over-voltage shutdown codes.
- ✓Firmware corruption and motion parameter loss — Sudden power interruptions (common in Indian industrial areas), voltage spikes from generator switching, and wear of the microcontroller flash memory cause ELECTRO-PRO MCM and servo controllers to lose calibration data and firmware integrity, resulting in erratic motion or complete axis lockout.
- ✓Thyristor and gate-drive failures in DC-Pro drives — ELECTRO-PRO DC-Pro controllers used in older pressing and rolling mill equipment experience thyristor avalanche and gate-drive transformer saturation when subjected to repetitive load transients, phase-angle misfires, or inadequate snubber circuits. Indian power grid harmonics exacerbate the stress.
- ✓CANopen and communication protocol timeouts — ELECTRO-PRO MCM-300/500 controllers lose synchronization with master PLCs due to EMI pickup on CANopen twisted pairs, incorrect termination resistors, or corrupted device configuration files stored in non-volatile memory. Symptoms include loss of encoder feedback, drive commands ignored, and watchdog resets.

Frequently Asked Questions — ELECTRO-PRO Repairs
Do you repair ELECTRO-PRO equipment anywhere in India?+
Yes. Synchronics repairs the entire ELECTRO-PRO servo drive, AC vector drive, DC controller, and spindle drive portfolio across India. We offer same-day pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and 50+ other cities, with repairs completed at our Vadodara, Gujarat facility. Standard turnaround is 5-7 working days; express service available for critical plant stoppages.
What is the difference between ELECTRO-PRO SD-3500 and SD-5000 servo drives?+
ELECTRO-PRO SD-3500 is rated for motors up to 15kW with encoder feedback and is common in small CNC machines and textile winding systems. The SD-5000 extends to 30kW capacity with dual-feedback support (resolver and encoder) and advanced harmonic filtering — standard in precision grinding and boring centers. Both use identical control architecture, so Synchronics applies the same diagnostic protocol and component sourcing, though power stage components differ.
Why do ELECTRO-PRO drives fail more frequently in Indian manufacturing plants?+
ELECTRO-PRO equipment is designed for European industrial environments with controlled ambient temperatures and stable power supplies. Indian manufacturing — especially in textile mills, foundries, and coastal areas — exposes drives to temperatures exceeding 45°C, humidity spikes, harmonic-rich grid power, and frequent voltage transients. This accelerates IGBT aging, capacitor degradation, and connector corrosion. Synchronics engineers are trained to diagnose and prevent these environment-specific failures using thermal imaging, harmonic analysis, and industrial-grade component upgrades.
Can Synchronics repair ELECTRO-PRO drives without original spare parts?+
We maintain genuine ELECTRO-PRO spare parts inventory including IGBT modules, gate-drive cards, resolver converter boards, and capacitor banks. For obsolete models, Synchronics sources cross-compatible components from certified distributors and performs careful application engineering to ensure compatibility. In rare cases where original parts are unavailable, we recommend controlled replacement with equivalent rated alternatives, always with written risk assessment and customer approval.
What warranty do you offer on repaired ELECTRO-PRO equipment?+
All ELECTRO-PRO repairs carry a 12-month comprehensive warranty covering parts and labor against manufacturing defects. Extended 24-month warranty is available. Every repaired drive undergoes 48-hour burn-in testing, no-load acceleration and deceleration cycles, and full functional validation on our test stands before dispatch. We issue a detailed technical report documenting the fault root cause, repair procedure, and performance test results.
How do I send my ELECTRO-PRO 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 ELECTRO-PRO 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 ELECTRO-PRO 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 ELECTRO-PRO 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.
