💡 What is a VFD inverter used for in CNC machines and how does it control spindle speed and torque?

A handy explanation:

- It converts incoming power into an adjustable frequency and voltage to drive the motor
- It allows a wide spindle speed range (0-3000 Hz) to match cutting conditions
- It supports RS485 MODBUS for CNC controller integration
- It accepts single- or three-phase input and outputs three-phase power to the spindle
