DYNAPRO Product Lines We Repair
Our engineers are trained on the full DYNAPRO product range. Below are the major product families we service.
DYNAPRO Servo Drives
High-performance AC servo amplifiers controlling brushless servo motors across positioning, indexing, and continuous-duty applications. Common issues include encoder communication loss, overcurrent faults, thermal runaway, and firmware corruption requiring specialised servo tuning.
DYNAPRO VFD (Variable Frequency Drives)
Industrial-grade vector and scalar VFDs for AC motor speed control in pumps, fans, compressors, and conveyors. Typical faults include DC bus capacitor failure, IGBT module burnout, brake resistor open circuit, and communication protocol errors on Modbus/Profibus networks.
DYNAPRO Motion Controllers
Standalone and networked motion controllers for multi-axis synchronisation, electronic camming, and coordinated drive operation. Repair work includes PLC firmware updates, Ethernet port replacement, I/O card failures, and axis parameter recalibration.
DYNAPRO Stepper & Stepper Drivers
Microstepping drivers and controllers for precision positioning in textile machinery, printing equipment, and laboratory automation. Common failures are output phase open circuits, enable relay malfunction, and step-pulse signal conditioning problems.
DYNAPRO Regenerative Units & Braking Resistors
Energy recovery and dynamic braking modules for hoisting equipment, crane systems, and multi-axis servo applications. Frequent issues include resistor thermal stress, regeneration circuit capacitor degradation, and contactor relay chatter.

6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common DYNAPRO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNAPRO equipment arriving at our workshop.
- ✓DYNAPRO servo drive encoder communication failure — Broken encoder cable, damaged SSI or EtherCAT connector, or firmware mismatch between drive and encoder interface module causing loss of position feedback.
- ✓DYNAPRO VFD DC bus undervoltage shutdown — Electrolytic capacitor bank degradation (especially in hot plant environments across Indian summers), partial rectifier diode failure, or loose AC mains connection causing insufficient DC intermediate voltage.
- ✓DYNAPRO motion controller Ethernet port non-responsive — PHY layer chip failure, corroded RJ45 connector contacts, or firmware hang in network stack preventing TCP/IP communication and parameter download.
- ✓DYNAPRO IGBT power module open or short circuit — Gate oxide stress from electrical surges, thermal cycling fatigue in VFD output stages, or insufficient snubber capacitor charge dissipation during high-speed switching.
- ✓DYNAPRO stepper driver output phase lockup or erratic stepping — Microstepping DAC failure, H-bridge MOSFET thermal shutdown, or step/direction pulse signal degradation due to long cable runs in noisy factory environments.
- ✓DYNAPRO regenerative unit brake resistor thermal trip during hoist descent — Undersized resistor element for peak energy dissipation, failed thermal protection relay, or inadequate heat sink mounting causing temperature runaway in continuous braking duty.

Frequently Asked Questions — DYNAPRO Repairs
Do you repair DYNAPRO equipment anywhere in India?+
Yes. Synchronics repairs the complete DYNAPRO product range across all of India — servo drives, VFDs, motion controllers, stepper drivers, and regenerative braking systems. We offer PAN-India door pickup from major industrial centres including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and smaller cities. All repairs are performed at our flagship facility in Vadodara, Gujarat, with average turnaround of 5-7 working days.
What is your experience repairing DYNAPRO servo drives and motion controllers?+
Synchronics has repaired thousands of DYNAPRO servo drives and motion controllers across Indian manufacturing plants for over 20 years. Our engineers are proficient in DYNAPRO servo tuning software, EtherCAT commissioning, parameter backup/restore, and firmware updates. We maintain current technical documentation and have direct vendor support channels for obsolete or custom DYNAPRO modules. Your servo positioning accuracy and response are fully validated before return.
Can you repair DYNAPRO VFD IGBT failures and capacitor degradation?+
Yes, absolutely. DYNAPRO VFD IGBT module failures and electrolytic capacitor aging are among our most frequent repairs in Indian industrial plants exposed to high ambient temperatures and voltage transients. Synchronics performs full curve-tracer testing of IGBT dice, replaces failing modules with OEM-matched semiconductors, upgrades snubber and gate protection circuits, and replaces aged capacitor banks with fresh units rated for extended life. We deliver comprehensive warranty on all power module work.
Do you repair DYNAPRO regenerative braking units for hoist and crane systems?+
Yes. We specialise in repairing DYNAPRO regenerative units and dynamic braking resistors used in Indian hoisting equipment, gantry cranes, and multi-axis servo systems. Our engineers correctly size brake resistors for your specific duty cycle, replace failed thermal protection relays, upgrade heatsink assemblies, and validate sustained braking performance. We also offer energy recovery circuit optimisation to improve system efficiency.
What warranty and support do you offer on DYNAPRO repairs?+
All DYNAPRO repairs at Synchronics come with a full 12-month warranty covering parts and labour against manufacturing defects. We provide complimentary technical consultation for parameter tuning, firmware selection, and integration issues. Customers receive detailed repair reports, component photographs, and before/after test data. We also maintain spare DYNAPRO modules in stock for emergency on-site support across Gujarat and Western India.
How do I send my DYNAPRO 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 DYNAPRO 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 DYNAPRO 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 DYNAPRO 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.
