Product Description

Automatic Torque Boost 3hp Vfd Phase Converter CE Certification

Automatic Torque Boost Three Phase VFD Complete Separation Straight Line Ramp And S-Curve Ramp


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.

Jog control

Jog frequency: 0.00Hz~50.00Hz

Jog acceleration and deceleration tome:0.0s~6500.0s

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.

The 0.4~37kW inverter of CM540 series don’t have external dc reactor terminal.

The G132 and above must use standard external DC reactor along with the cargo when factory arrange the deliver. Users need to remove the short circuit copper bars between the main circuit terminals (+) and P when installation, then the DC reactor could be connected between the (+) and P, there is no pole between the reactor terminals and the inverter terminals (+), P. After installing the DC reactor, the short circuit copper bars between (+) and P short circuit is no longer used.
