DYNODRIVE Equipment We Repair — By Category
DYNODRIVE Product Lines We Repair
Our engineers are trained on the full DYNODRIVE product range. Below are the major product families we service.
Dynodrive VFD Series
Three-phase variable frequency drives for AC motor speed control and energy optimization. Common issues include firmware corruption, thermal runaway in power IGBTs, capacitor degradation under Indian high-temperature/humidity climates, and communication bus failures in networked installations.
Dynodrive Servo Drive Range
Closed-loop servo drives for precision positioning in textile machinery, packaging equipment, and CNC applications. Typical faults include encoder signal loss, reference voltage drift, commutation timing errors, and phase-leg shorts in MOSFET bridges.
Dynodrive DC Drive Controllers
Thyristor and transistor-based DC drive units for steel rolling mills, paper machinery, and crane hoist systems. Prone to armature winding shorts, field winding open circuits, gate driver IC failures, and heat sink corrosion in coastal/humid Indian locations.
Dynodrive Soft Starter Modules
Electronic soft-start controllers for reduced inrush current and mechanical shock absorption in pump stations and blower installations. Common repair calls involve SCR firing circuit faults, current-limiting resistor burnout, and thermal overload sensor malfunction.
Dynodrive IO Module Board
Distributed input/output interface boards for multi-axis motion control and process monitoring. Exhibit connector corrosion, relay coil failures, optocoupler degradation, and firmware synchronization errors in networked setups.

Common DYNODRIVE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNODRIVE equipment arriving at our workshop.
- ✓Dynodrive VFD IGBT power module short-circuit — Indian industrial environments subject Dynodrive drives to sustained ambient temperatures of 40-50°C, moisture ingress from non-sealed terminal boxes, and voltage transients from unswitched loads. IGBT junctions degrade rapidly, causing phase-to-phase shorts and DC bus collapse.
- ✓Dynodrive servo drive encoder communication loss error — Incremental encoders on Dynodrive servo systems suffer intermittent signal dropout due to connector oxidation, EMI coupling from adjacent power cables, or firmware version conflicts after field updates. The servo drive triggers E-STOP mode, halting production immediately.
- ✓Dynodrive VFD overtemperature shutdown with restart inhibit — Thermal sensors in Dynodrive VFDs drift after 5-8 years due to RTD sensor aging and PCB solder joint fatigue near heat-dissipating components. The drive locks into permanent thermal fault state even when cooled, blocking production restart.
- ✓Dynodrive DC drive armature winding phase-to-phase short — Dynodrive DC drives in Indian steel mills and paper plants operate under severe mechanical vibration, thermal cycling, and moisture exposure. Armature windings develop chafed insulation, leading to progressive short-circuit current and winding burnout.
- ✓Dynodrive soft starter SCR gate driver IC malfunction — The isolation gate driver ICs in Dynodrive soft starter modules are susceptible to transient overvoltage during sudden load rejection or phase-loss scenarios common in Indian power distribution networks. Secondary breakdown or latch-up can occur, destroying the driver silicon.
- ✓Dynodrive IO module relay coil open-circuit or pitting — Dynodrive IO relays in textile mills and packaging lines undergo high-frequency switching (50-100 operations per minute). Coil insulation degrades under sustained relay energization heat, and contact pitting accumulates from arcing due to inadequate load-side snubbing.

Frequently Asked Questions — DYNODRIVE Repairs
Do you repair Dynodrive equipment anywhere in India?+
Yes. Synchronics repairs the full Dynodrive product range — VFDs, servo drives, DC controllers, soft starters, and IO modules. We offer PAN-India door pickup and courier from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, and all major industrial cities. Equipment is centralized to our factory-certified lab in Vadodara, Gujarat for rapid diagnostics and repair.
What is the typical turnaround time for Dynodrive VFD repair?+
Standard Dynodrive VFD repairs (capacitor replacement, IGBT module swap, firmware reload) take 3-5 working days from receipt. Complex faults requiring custom component sourcing or armature rewinding extend to 7-14 days. We provide real-time status updates via email and phone, and offer express same-day diagnostics for critical downtime situations.
Do you stock Dynodrive spare parts and modules?+
Synchronics maintains active inventory of Dynodrive power modules, capacitor banks, gate driver ICs, and encoder connection kits. For discontinued or specialized assemblies, we leverage our network of authorized distributors across India to source OEM-equivalent components within 48 hours. All parts are tested before integration into repaired drives.
Can you repair Dynodrive servo drives with encoder signal faults?+
Yes. Encoder faults are among the most frequent servo drive issues we resolve. Our diagnostic procedure includes oscilloscope capture of differential encoder signals, connector resistance testing, cable continuity verification, and firmware diagnostics using Dynodrive native tools. We re-terminate shielded cables to eliminate EMI coupling and reprogram sensor calibration tables to restore zero-error positioning within 0.01 mm.
Does Synchronics offer preventive maintenance contracts for Dynodrive equipment?+
Yes. We offer customized preventive maintenance (PM) plans for installed Dynodrive drives, including quarterly firmware updates, thermal stress cycling, capacitor health trending, and solder joint X-ray inspection. PM contracts reduce unexpected downtime by 70% and extend drive lifespan by 4-6 years in high-temperature Indian environments. Contact our sales team for on-site assessments and quotation.
How do I send my DYNODRIVE 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 DYNODRIVE 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 DYNODRIVE 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 DYNODRIVE 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.
