    Tips: Variable frequency drive control mode

    Vector control
    Vector control is to control the size and phase of the stator current of the motor through the vector coordinate circuit, so as to control the excitation current and torque current of the motor in the d, q, 0 coordinate axis system respectively, and then achieve the purpose of controlling the motor torque. By controlling the action sequence and time of each vector and the action time of the zero vector, various PWM waves can be formed to achieve various control purposes. At present, the vector control methods actually used in the VFD mainly include the vector control method based on slip frequency control and the vector control method without speed sensor.

    V/F control
    V/F control is in order to obtain the ideal torque-speed characteristic, based on the idea that while changing the power frequency for speed regulation, it is proposed to keep the magnetic flux of the motor constant. Basically, general-purpose VFD use this control method. The V/F control inverter is very simple, but this method cannot achieve higher control performance. Moreover, at low frequencies, torque compensation must be performed to change the low-frequency torque characteristics.

    Existing reviews of 30 hp VFD, 1-Phase 220V to 3-Phase 380V VFD
    Application of VFD
    My application is: A cnc lathe with 20 hp. 3 phase 50A requirements. Can we use variable frequency drive with 1-phase, 220V input to 3-phase output to run such application?

    ATO Responded
    Yes, but please, note that the VFD can be used for motor individually not for your whole CNC equipment/machine service panel, with direct connection between VFD output terminals and motor input terminals, nothing in between. Also, the motor will be fully controlled (on/off/speed control) via VFD buttons only.
