Inverter (VFD) repair & setup
WIU TECH repairs AC frequency inverters, also called variable frequency drives (VFDs), and sets up their parameters, such as voltage, frequency and motor settings, so the drive and motor work correctly together. We're based in Sungai Besi, Kuala Lumpur, serving KL, Selangor and Negeri Sembilan on-site, and customers across Malaysia on request.

Can you set up an inverter on site?
Yes. We can configure inverter parameters at your site and test them with the motor.
My inverter shows an error code. What should I do?
WhatsApp us a photo of the display showing the code, plus the inverter's label. We'll tell you what it likely means and the next step.
Should I repair the motor or the inverter?
Sometimes the fault is in the motor, not the drive, or the other way round. We check both, so you don't pay to fix the wrong part.
