Systematic Execution
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.
Safe Dispatch & Support
Field Symptom Recognition
Experiencing Drive Problems?
Look for these common industrial drive warning signs. Our bench diagnostic process isolates the root cause before catastrophic module explosion occurs.
No Power / Display Off
Blown primary fuse, rectifier failure, or damaged SMPS power section.
Overcurrent (OC) Fault
Shortened IGBT module, motor insulation breakdown, or gate circuit defect.
Overvoltage / Undervoltage
Regenerative brake resistor defect, grid surge, or worn DC bus capacitors.
Motor Not Running / Stall
Phase imbalance, missing trigger pulses, or defective current sensors (CTs).
Thermal Overheat Trip
Failed cooling fans, blocked heat sink airflow, or dry thermal paste.
Blank Keypad / Bus Error
Damaged ribbon cables, internal 5V/24V rail sag, or corrupted microcontroller.
Solar Drive Erratic Output
Faulty MPPT tracking logic, solar panel string leakage, or DC fuse blown.
Automation Encoder Alarms
Encoder line noise, broken feedback interface, or sync angle loss on servo.
Engineering Note: Fault symptoms can stem from line transients, thermal fatigue, or gate circuitry degradation. A bench inspection is required before confirming the repair scope.
