- Perform VFD parameter setting, autotuning, motor identification, and functional testing.
- Configure acceleration/deceleration, speed references, current limits, protections, PID control, and application-specific parameters.
- Verify motor rotation, motor current, frequency, speed, and operating conditions.
- Commission VFD panels, MCC interfaces, bypass arrangements, and associated control circuits.
- Prepare commissioning reports and parameter backup records.

2. VFD Troubleshooting & Service

- Diagnose VFD faults, alarms, trips, and abnormal operating conditions.
- Troubleshoot overcurrent, overvoltage, undervoltage, overload, earth fault, communication, overheating, and motor-related problems.
- Analyze fault history and drive parameters to identify root causes.
- Troubleshoot VFD control wiring, feedback signals, digital/analog I/O, and interlocks.
- Carry out site-level corrective maintenance and emergency breakdown support.
- Coordinate with the technical team for complex drive failures and component-level issues.

3. Preventive & Breakdown Maintenance

- Conduct preventive maintenance of VFDs and drive panels.
- Inspect cooling fans, heat sinks, DC bus condition, terminals, cables, contactors, fuses, and control components.
- Check electrical connections, insulation, earthing, and ventilation.
