Commander C300 repair and refurbishment
The Commander C300 is a higher-capability drive in the Commander range, featuring on-board PLC functionality and extended I/O. Its more complex control architecture means diagnostic depth is important — we carry out full bench evaluation before confirming any repair.

Commander C300 repair FAQs
Can you repair a Commander C300 with a communication fault on a fieldbus option module?
Yes. Fieldbus option module faults and control card communication failures are within our diagnostic scope. We test both the base drive and option card to identify the specific failure.
My Commander C300 keeps tripping on overtemperature even in a cool environment — why?
An overtemperature trip in a cool environment often indicates a faulty thermistor or blocked heatsink rather than genuine overheating. We check both during the bench diagnostic.
Do you repair Commander C300 drives with onboard PLC faults?
We focus on hardware repair. If the onboard PLC application is causing faults, we will identify whether the issue is hardware or software and advise accordingly.
