DOFASCO Product Lines We Repair
Our engineers are trained on the full DOFASCO product range. Below are the major product families we service.
Dofasco Coil Tension Control Systems
Closed-loop feedback systems managing strip tension during coil unwinding and processing. Common failures include load cell signal degradation, feedback amplifier burnout, and PLC communication loss due to moisture ingress in mill environments.
Dofasco Distribution Control Units (DCU)
Networked controllers for multi-zone coil coating and finish application. Typical faults: firmware corruption from power surges, CANopen communication errors, solenoid driver failures, and sensor input noise on active production lines.
Dofasco Coil Entry and Exit Automation
Servo-driven positioning and synchronization for strip edge control and coil tracking. Repair issues include encoder signal loss, stepper motor driver thermal shutdown, and loss of absolute position reference after unexpected stops.
Dofasco VFD Drive Systems for Coil Handling
Variable frequency drives powering unwinding, coating application, and recoiling motors. Failures typically involve IGBTs, capacitor degradation, control board firmware issues, and protection relay faults due to steel mill electrical noise.
Dofasco Operator Interface Panels (OIP)
HMI touchscreens and pushbutton stations for production line control and diagnostics. Common defects: capacitive touch layer delamination, communication module dropout, SD card corruption, and backlight LED failure.
Dofasco Mainline PLC Modules
Ruggedized programmable controllers for coordinating entire finish line sequences. Typical problems: input/output (I/O) card failures, memory module corruption, clock battery depletion, and Ethernet port damage from industrial surge.

Common DOFASCO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOFASCO equipment arriving at our workshop.
- ✓Coil tension feedback signal loss or drift — Load cell connectors corroded by mill humidity; shield grounding degraded; amplifier input stage damaged by signal overvoltage from nearby switching equipment. Dofasco systems require tight analog signal integrity in steel mills.
- ✓CANopen communication timeout between DCU and PLC — CAN termination resistors open or missing; firmware version mismatch after partial updates; electromagnetic interference (EMI) from adjacent induction heating or motor starters inducing noise on the CAN bus.
- ✓VFD IGBT module thermal shutdown during production run — Electrolytic capacitor ESR (equivalent series resistance) increased from age or thermal cycling; heatsink thermal paste dried; soft-start contactor stuck, causing continuous high inrush current. Dofasco coil drives run continuously at high utilization.
- ✓Absolute encoder position loss after emergency stop activation — Encoder battery-backed RAM cleared by power loss before safe shutdown; servo motor loses commutation reference; firmware watchdog timer triggers reset, wiping position registers. Dofasco servo systems lack redundant position storage.
- ✓HMI touchscreen becomes unresponsive or shows garbled graphics — Display ribbon cable disconnected from vibration; capacitive touch controller IC loses calibration or suffers firmware corruption; backlight LED driver capacitor bulges; hot climate causes LCD pixel cell degradation.
- ✓I/O module channels reading false or stuck values — Input isolation optocoupler LEDs age and dim, reducing signal margin; output relay contacts weld or oxidize from arcing; firmware corruption of I/O configuration table. Dofasco modules experience thousands of on-off cycles daily.

Frequently Asked Questions — DOFASCO Repairs
Do you repair Dofasco equipment anywhere in India?+
Yes. Synchronics repairs the full Dofasco industrial control range — tension controllers, DCU modules, servo drives, VFDs, HMIs, and PLC systems. We offer PAN-India door-to-door pickup from all major cities: Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, and beyond. All repairs are handled at our primary facility in Vadodara, Gujarat, with rapid turnaround and full test documentation.
What is a typical turnaround time for Dofasco coil tension controller repair?+
Tension controllers (DTC-3000, DTC-5000) typically require 5-7 working days for diagnosis, component replacement, and closed-loop testing. Rush service available for critical production stops — we prioritize units affecting rolling mill schedules. Turnaround includes full calibration using load cell simulation and strip feedback validation.
Can Synchronics repair Dofasco VFDs with burnt IGBT modules?+
Yes. We replace failed IGBT modules, snubber diodes, and drive capacitors, then perform full thermal cycling and dynamic load testing. We stock compatible IGBT modules for Dofasco DHD series (7.5kW to 30kW). Repaired drives are tested on our vector drive test bench with regenerative load to ensure rated current and overload capacity before shipment.
Do you offer spare parts for Dofasco PLC modules and I/O cards?+
Yes. Synchronics stocks and supplies original Dofasco replacement parts including PLC-M200/M500 I/O cards, power supplies, memory modules, and communication interface cards. We also maintain a used-but-tested inventory of legacy Dofasco modules for customers with older finish-line installations. All parts come with test certificates and 6-month warranty.
What is your experience with Dofasco CANopen fieldbus troubleshooting?+
Our 180+ engineers include specialists trained on industrial fieldbus protocols. We diagnose CANopen communication failures using protocol analyzers, verify CAN bus impedance, test termination resistors, and resolve firmware version conflicts between DCU nodes and mainline controllers. We also retrofit EMI shielding on customer sites to eliminate noise-induced dropouts in noisy steel mill environments.
How do I send my DOFASCO 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 DOFASCO 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 DOFASCO 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 DOFASCO 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.
