Thanks for your electrical question Glabrous.
Yes – I am familiar with VFD, Variable Frequency Drives and I have installed quite a few in 3 phase 480 volt motor control applications including large industrial pumps and air handler units. The VFD Control Interface, also known as a Human Machine Interface (HMI) provides start, stop and speed adjustments. The HMI may have a keypad and display screen or led indicator lights to provide information about the settings and operation of the VFD unit. Each VFD unit comes with a helpfulÂ installation manual complete with wiring diagrams.
