Product Description

380V 0.75KW Vector Inverter Frequency Drive For Three Phase Motor

380V 0.75KW Three Phase VFD Frequency Driver High Torque Vector Inverter Vector control 0~600Hz


The CM540 series is a high torque type vector inverter. Its motor control performance increases obviously. The inverter can implement the control of asynchronous motor and permanent magnet synchronous motor (PMSM), supports multi-kind PG and IO cards(including CAN COMMUNICATION).The function is more powerful. It is used to drive various automation production equipment involving textile, paper-making, machine tool, packing, food, elevator, crane, pertrolum machinery, fan, pump etc.


The CM540 series AC drive incorporates the following improvements:

1. Control of asynchronous motor and PMSM : It supports vector control of three-phase AC asynchronous motor and three-phase AC MSM.

2. Diversified control modes : It supports four control modes, namely, sensor less flux vector control (SFVC), closed-loop vector control (CLVC) and V/F control, V/F separating control.

3. Multiple communication protocols : It supports communication via Modbus-RTU, CAN link.

4. Multiple encoder types : It supports various encoders such as differential encoder, open-collector encoder or push-pull output encoder.

5. All-new SFVC algorithm : It introduces an all-new sensor less flux vector control (SFVC) algorithm that gives better low-speed stability, enhanced low-frequency loading capacity, and supports torque control.

6. External powerful expansion cards, could realize CAN communication function, jection machine function, motor PT100 thermal protection etc.

Simple PLC, multistage speed operation It implements up to 16 speeds via the simple PLC function or combination of DI terminal states.
Built-in PID It can keep constant output voltage automatically when the mains voltage changes.
Automatic voltage regulation(AVR) Automatically maintain a constant output voltage when grid voltage changes.
Over voltage/Over current loss of speed control Automatic limit of the current and voltage during the operation, prevent frequent over current and over voltage
Rapid current limit Minimizing over-current fault and protect the normal operation of converter.
Torque limit and control "Excavator" characteristics, automatic limit of the torque during the operation, to prevent frequent over-current trip. Closed-loop vector mode torque control can be achieved.
