Higher control performance

  • Variable control modes: vector control with speed sensor/without speed sensor , dynamic torque vector control and  V/f control.
  • Quicker response: quicker response to current and speed. 
  • Longer durability to overloading: High Duty (100% in 3 sec. 150% in 60 sec.), applied to general purpose; Normal Duty (120%in 60sec.), applied to fan and pump etc.

Double Specification

  • Choose HD/ND by setting parameters
  • Choose different modes according to your purpose

Environment friendly

  •  Follow RoHS
  •  More environmentally friendly
