Technical FAQs
What details are required before sending a VFD for repair evaluation?
Please share the drive manufacturer, model code, kW/HP rating, displayed fault code, and a brief description of the operating failure.
Can all faulty VFDs be repaired?
Repair feasibility depends on component availability, extent of PCB damage, and overall physical condition. Equipment is assessed upon receipt before quotation.
