DRIVE SYSTEM COMPANY Product Lines We Repair
Our engineers are trained on the full DRIVE SYSTEM COMPANY product range. Below are the major product families we service.
DSC VFD Series
Three-phase and single-phase variable frequency drives ranging 0.5 kW to 250 kW for pump, fan, and conveyor applications. Common repair issues include IGBT module thermal cycling failures, resolver signal loss, and firmware corruption after power transients.
DSC Servo Drive Range
Closed-loop servo amplifiers with encoder feedback for precision positioning in textile machinery, printing presses, and packaging lines. Typical faults involve Hall sensor misalignment, commutation timing drift, and phase loss detection circuit failures.
DSC Motion Controller Line
Standalone and embedded motion control processors with CANopen and Modbus support for multi-axis synchronization. Repair focus includes firmware flash corruption, real-time clock battery replacement, and I/O terminal module delamination.
DSC Power Supply Modules
24 VDC and 48 VDC isolated supply boards used in drive control circuits and sensor conditioning networks. Capacitor dry-out, transformer winding faults, and post-surge voltage regulation instability are frequent repair scenarios.
DSC HMI Touch Panels
7-inch to 15-inch industrial touch screens with integrated Ethernet and USB connectivity for real-time drive monitoring. Common defects include LCD panel backlight degradation, resistive touch layer delamination, and communication protocol firmware issues.
DSC Resolver-to-Digital Converters
Precision analog-to-digital conversion modules for synchro and resolver feedback in legacy and modern servo loops. Repair work addresses resolver winding insulation breakdown, ADC linearity loss, and phase detection circuit drift.

Common DRIVE SYSTEM COMPANY Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DRIVE SYSTEM COMPANY equipment arriving at our workshop.
- ✓IGBT Short Circuit - Drive Output Stage Failure — Thermal cycling stress and gate-drive voltage overshoot during high-current transients cause IGBT junction degradation in DSC VFD output bridges. Moisture ingress into power module potting accelerates dielectric breakdown, leading to catastrophic gate-source failure and immediate drive shutdown.
- ✓Resolver Signal Loss - No Servo Feedback — DSC servo systems rely on resolver signal conditioning for commutation timing. Corroded resolver connectors, broken cable shields, and failed signal conditioning amplifiers degrade resolver amplitude and phase, causing the servo drive to lose position feedback and trigger E-RESOLVER or E-COMM fault codes.
- ✓Firmware Corruption - Boot Loop or Stuck Menu — Power supply transients, incomplete firmware updates, and flash memory wear in older DSC drives cause boot loader code corruption. The drive enters a reset loop displaying version mismatches or frozen menu screens, rendering the equipment inoperable without firmware restoration.
- ✓Capacitor Dry-Out - Voltage Regulation Failure — Aluminum electrolytic capacitors in DSC power supplies and drive input stages degrade in high-ambient Indian industrial environments exceeding 50°C. Dielectric loss and ESR rise cause DC rail voltage droop, triggering under-voltage shutdowns or erratic control behavior, especially under load.
- ✓Modbus Timeout - Communication Link Down — DSC motion controllers and HMI panels communicate via Modbus RTU over RS-485 networks. Noise coupling from adjacent power cables, termination resistor failure, and transceiver IC degradation cause communication frame errors and complete link loss, halting synchronized multi-drive operation.
- ✓Hall Sensor Offset - Commutation Timing Error — DSC servo drives use Hall effect sensors to detect rotor position and trigger commutation switching. Magnet aging, mechanical misalignment, and thermal drift in sensor conditioning circuits cause Hall pulse timing errors, resulting in reduced torque, motor cogging, and temperature rise during low-speed operation.

Frequently Asked Questions — DRIVE SYSTEM COMPANY Repairs
Do you repair Drive System Company equipment anywhere in India?+
Yes. Synchronics repairs the full Drive System Company product range - VFDs, servo drives, motion controllers, power supplies, and HMI panels. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. Single facility in Vadodara, Gujarat handles all incoming diagnostics, repair, and testing with 5-10 business day turnaround for most faults.
What is the most common Drive System Company servo drive fault in Indian plants?+
Resolver signal conditioning failure is the most frequent servo drive issue we encounter in Indian textile and automotive plants. The high dust and humidity from monsoon seasons cause resolver connector corrosion and signal amplitude dropout, triggering E-RESOLVER fault codes. Synchronics performs deep resolver signal path diagnostics and rebuilds all conditioning amplifier stages with upgraded conformal coating for tropical climate durability.
Can you repair older DSC drives no longer supported by the manufacturer?+
Absolutely. Synchronics maintains comprehensive spare parts inventory and legacy firmware images for Drive System Company drives from the 1990s onward. Many Indian sugar mills and textile units still operate DSC drives from 2005-2010 era. We repair and upgrade legacy DSC equipment with modern component substitutes and firmware patches, extending equipment life by 5-10 years at a fraction of replacement cost.
Do you provide warranty on Drive System Company repairs?+
Yes. All Synchronics Drive System Company repairs carry a 12-month parts and labor warranty covering the same fault. If the identical failure recurs within warranty, we repair at no cost. We also offer extended 24-month warranty on critical components like IGBT modules and servo amplifiers for an additional service charge.
How quickly can Synchronics repair a failed DSC VFD affecting my production line?+
For critical production downtime, Synchronics offers express 48-hour turnaround on Drive System Company VFD repairs (subject to parts availability). We also maintain loaner DSC drive units that match your power rating and voltage class - you can swap the loaner immediately while we repair your original unit. This service is available in Vadodara and surrounding metro areas with same-day drive exchange.
How do I send my DRIVE SYSTEM COMPANY 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 DRIVE SYSTEM COMPANY 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 DRIVE SYSTEM COMPANY 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 DRIVE SYSTEM COMPANY 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.
