First we need one power cable.With five cores, i.e. 3-1-1 (three-line line one-zero line one ground line); The second to the motor end of the cable, generally only one, with a four-core cable, that is, 3 -1 (three line of fire one line). If the motor is soft-startwithe with a drive, just one five-core cable and a four-core cable.
Inverter: Variable-frequency Drive, VFD is the application of inverter technology and microelectronics technology to control the power control equipment of AC motors by changing the way the motor operates. The inverter is mainly composed of rectification (AC DC), filtering, inverter (DC ac), braking unit, drive unit, detection unit microprocessing unit, etc.
