DYNADRIVE Product Lines We Repair
Our engineers are trained on the full DYNADRIVE product range. Below are the major product families we service.
DYNADRIVE VFD Series
General-purpose variable frequency drives ranging from 0.5 kW to 500 kW for AC induction motor speed control. Common faults include IGBT module thermal stress, DC bus capacitor bulging, and control signal noise causing erratic speed variation.
DYNADRIVE Servo Drive Controllers
High-performance servo drive units for closed-loop motion applications requiring encoder feedback and dynamic load compensation. Typical failures include encoder connector corrosion, firmware corruption from power glitches, and tuning parameter loss.
DYNADRIVE Regenerative Braking Modules
Energy recovery units that return power to the grid during deceleration. Prone to short-circuit failures in freewheeling diodes, capacitor bank leakage, and gate driver circuit faults under rapid load reversals.
DYNADRIVE Integrated Motion Controllers
Multi-axis control platforms combining drive and logic functions in compact form factors. Common issues include field IO isolation failures, Ethernet port communication dropouts, and real-time kernel crashes during high-frequency interrupt cycles.
DYNADRIVE Brake Control Interface
Specialised modules managing electromagnetic brake coils in hoisting and vertical motion applications. Frequent faults include solenoid driver relay wear, surge suppression diode failure, and 24VDC supply instability causing intermittent brake engagement.

Common DYNADRIVE Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DYNADRIVE equipment arriving at our workshop.
- ✓IGBT Module Failure — No Three-Phase Output — DYNADRIVE drives use discrete IGBT modules in a 6-pack configuration. Thermal cycling from inadequate heatsink contact, moisture ingress through unsealed connectors, and sustained overcurrent during jam detection cause gate oxide breakdown and module short-circuit. This halts all motor power immediately.
- ✓DC Bus Capacitor Bulging — Reduced Holding Voltage — DYNADRIVE VFD units use electrolytic capacitor banks rated 400–800V. Voltage ripple stress from unfiltered input, sustained operation at high ambient temperature (40-50°C in Indian industrial plants), and end-of-life degradation cause dielectric breakdown and electrolyte vaporisation, resulting in bloated can and voltage sag during acceleration.
- ✓Encoder Signal Loss — Servo Loop Instability — DYNADRIVE servo drives rely on quadrature encoder feedback at 20 kHz sampling. Vibration causes connector pin wear, contaminated connectors from humidity and metal shavings in mill environments, and shielded cable break near motor terminals interrupt signal continuity. Drive detects missing commutation pulses and triggers position-error shutdown.
- ✓Firmware Corruption — Drive Will Not Boot — Power interruptions during firmware upload, lightning strike transients through control wiring, or corrupted flash memory sectors in DYNADRIVE microcontroller cause checksum mismatch during power-on self-test. Drive enters safe state and displays error code E-FIRM.
- ✓Overtemperature Shutdown — Heatsink Fan Failure — Dust accumulation on DYNADRIVE heatsinks is endemic in Indian textile mills, steel plants, and cement facilities. Bearing wear in the cooling fan causes reduced airflow, thermostat trips at 85°C, and drive dethrottles output to 40% to prevent thermal runaway. Production line stalls repeatedly.
- ✓Parameter Loss After Power Cycle — DYNADRIVE controllers store tuning data (PID gains, motor constants, brake delay times) in battery-backed RAM. Depleted backup battery, disconnected battery connector, or corrupted EEPROM sector during firmware update cause loss of commissioning effort. Drive reverts to factory defaults, halting production lines.

Frequently Asked Questions — DYNADRIVE Repairs
Do you repair DYNADRIVE equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full DYNADRIVE product range — variable frequency drives, servo controllers, regenerative brake modules, integrated motion controllers, and brake interface units. We operate a centralised repair facility in Vadodara, Gujarat, with nationwide PAN-India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Kolkata, and all other major industrial cities. Typical turnaround is 5-10 business days.
What is the typical failure rate of DYNADRIVE IGBT modules in tropical climates?+
DYNADRIVE IGBT modules have a design life of 10-15 years in temperate climates, but in Indian industrial environments (40-50°C ambient, high humidity, dust), thermal stress accelerates degradation to 5-8 years. Synchronics recommends preventive heatsink maintenance, airflow verification, and thermistor calibration every 18-24 months. Early replacement of aged capacitors (visible bulging or ESR >10 ohms) prevents catastrophic IGBT failure and secondary damage to control circuits.
Can you recover customer parameters from a DYNADRIVE drive with corrupted flash memory?+
If backup memory is intact, Synchronics can extract parameters using factory diagnostic tools. However, if both flash and EEPROM are corrupted (lightning strike scenario), parameters are lost. We strongly recommend customers maintain SD card backup files or printed commissioning sheets. Our engineers can re-commission drives from baseline configuration within 2-3 hours if original motor nameplate and application data are available.
Do DYNADRIVE servo drives need re-tuning after capacitor replacement?+
No, capacitor replacement alone does not require servo tuning adjustment. However, Synchronics always validates DC bus voltage ripple (<3% at rated load) and confirms encoder signal integrity (no jitter >1 LSB) post-repair. If servo loop bandwidth has degraded (oscillation observed), we perform gentle PID re-tuning using a test load and data logging to restore original performance without overshooting.
What is Synchronics' warranty on DYNADRIVE drive repairs?+
Synchronics offers a 12-month comprehensive warranty on all repaired DYNADRIVE equipment covering parts and labour for the same fault. We use factory-equivalent IGBT modules, capacitor banks, and control components. Any warranty claim is processed within 48 hours with immediate turnaround repair and expedited shipping at no additional cost. We maintain spare inventory for urgent replacements in high-availability production lines.
How do I send my DYNADRIVE 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 DYNADRIVE 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 DYNADRIVE 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 DYNADRIVE 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.
