Frequency Inverters
VFD Repair Services in Ahmedabad, Gujarat
Repair solutions for variable frequency drives used in manufacturing machinery, extruders, heavy pumps, and plant motor-control centers (MCC panels).
About our vfd repair service
Variable frequency drives sit at the centre of most plant processes, so a VFD fault stops the line. We carry out complete diagnostic bench repair for low-voltage and medium-voltage plant VFDs, including units mounted inside MCC cabinets.
We routinely service VFDs deployed in textile machinery, plastic extruders, packaging lines, CNC axes, pumps, cooling tower fans and central Motor Control Centers.
What we work on
- Low-voltage and medium-voltage plant VFDs
- DC bus link capacitor bank testing and replacement
- Keypad parameter restoration and firmware inspection
- Output voltage balance and torque response verification
- Modbus, Profibus and RS485 communication interfaces
Faults we commonly resolve
- Overcurrent (OC) trips from shorted IGBT modules or gate circuit defects
- Overvoltage and undervoltage trips from worn DC bus capacitors or grid surges
- Blank keypad and bus errors from damaged ribbon cables or 5V/24V rail sag
- Regenerative brake resistor and brake chopper failures
- Motor stall and phase imbalance from missing trigger pulses

Our Drive Repair Process
A four-stage disciplined engineering workflow ensuring transparency, thorough bench testing, and rapid return to duty.
Step 01: Share Details
Send your drive make, model, kW rating, error fault code, and clear photos of the rating plate and terminal layout via WhatsApp or form.
Initial Scoping & Verification
Step 02: Inspection & Diagnosis
Equipment is safely evaluated in our GIDC Vatva workshop using curve tracers, oscilloscopes, and insulation testers to isolate hardware faults.
Detailed Diagnostic Report
Step 03: Repair & Testing
Component-level semiconductor replacement, trace repairing, conformal recoating, followed by simulated three-phase motor bench testing.
Dynamometer Bench Run
Step 04: Return & Support
The repaired drive is securely packed, dispatched back to your plant or farm site, accompanied by installation guidance and telemetry notes.
