Product Detail

product features

Tl latest moto-control specific digital signal processors (DSP) with clock frequency reaching up to 150Hz are adopted.

Asynchronous motors and permanent magnet synchronous motors control are supported, with accurate autotuning.Two independent motor profiles are programmed, and the switch over of the two motors control can be realized by parameter setting or terminal input.

ln V/Fcontrol mode accurate current limited control function makes sure of no over-curmernt fault occurred no matter the drives are running at acceleration/deceleration, or rotor locked status, well protecting the drves. h vector control mode, acurate torque limited control pledges powerful or moderate torque complying with application requirements , protecting machinery well.

In V/F separated control mode,output frequency and cutput voltage can be set respectively ft for applications,such as variable frequency power sources , torque motors, etc.
