VFD Repair & Troubleshooting

Frequency drive repair for AC and DC variable frequency drives, covering fault diagnosis, parameter recovery, and replacement where a rebuild is not economical. Work is done on your floor or on units shipped in, on the drive alone or the drive and PLC together.

WHAT WE DO

Most calls start with a fault code and a line that won't run. Give us the drive's model number and the code it's holding, and we'll scope the work before anyone is dispatched: a parameter correction handled over the phone, an off-site repair, or an on-site call.

VFD troubleshooting follows the drive's own fault history, the DC bus and capacitor condition, and the wiring between the drive and the motor, so the diagnosis is confirmed before parts are quoted. You receive the findings and an estimate on cost and lead time before work begins. Off-site repair covers ac drive repair and industrial drive repair across the platforms listed below, along with servo drive repair for indexing and positioning amplifiers. Parameters are backed up and documented before any unit is returned. Where a rebuild isn't economical, VFD replacement includes cross-referenced ratings, control wiring, and the VFD programming required to return the machine to its original operation.
