VEVOR Variable Frequency Drive, AC 220V Input 4KW Variable Frequency CNC Drive Inverter Converter, VFD 5.5HP 1 or 3 Phase Input, 3 Phase Output, CNC Motor Inverter Converter for Motor Speed Control

The supercurrent setting does not need to be set, currently, this option is not allowed, and the setting is fixed. Torque compensation means that the running torque of the motor is not enough at low speeds, and this parameter can be used to compensate. If you are single-phase 220v, please connect to R and T, and S does not need to be connected when it is empty. If you are three-phase 220v, then connect to RST. The three wires of the motor are connected to U, V, and W.

It is possible to use 4KW Variable Frequency CNC Drive on a 2.2 kW spindle motor.

No, single-phase motors cannot be driven by this inverter, it can only drive three-phase asynchronous motors with a voltage level of 220 volts.

Customers can control the drive by connecting an external latching pushbutton. Connect the pushbutton’s terminals to the drive’s GND and X1 terminals, and set parameter F001 to 1. When the pushbutton remains closed, the drive runs; when the pushbutton is released, the drive stops. If this answer does not resolve your issue, please contact us again for assistance.

No, it can only be controlled via external terminals.
