Open loop Flux Vector control type AC motor drives Z8 Series

Applicable to: fans, water pumps, central air conditioners, cooling towers, escalators, conveyor belts, plastic machinery, etc.


Key features:


  • Without speed sensing vector control, the carrier frequency is automatically optimized according to the radiator temperature and output current.
  • Unique magnetic flux compensation function maximizes output torque.
  • Up to 4 inverters can be connected in parallel.
  • The optional active front-end module can feed energy back to the power side to maintain DC bus voltage stability when the grid-side voltage fluctuates.
  • Frequency hopping function, forward/reverse jog function.
  • Smart startup after power interruption.
  • Constant pressure water supply control supports sleep mode.
  • Supports regular and reverse-enabled dual PID control.
  • Comes with two universal programmable timing controllers.
  • RS458 interface supports MODBUS and BACnet protocols.
  • Parameters can be set and downloaded through the USB interface, and the operating status of the inverter can be recorded through the USB interface by inserting an SD card.
  • EMC compatible.
  • IP30, IP66, IP54 and stainless steel body packaging.
