vfd

IMPORTANT NOTE

  • The variable frequency drive can only drive three-phase asynchronous motors and cannot be used as a power source.
  • If your motor is heavy load, pls choose a higher horsepower vfd than your motor's
  • To protect the VFD, be sure to press the red button "Stop" and turn off the power when you stop using it.

How to connect the motor

400hz spindle

50/60hz motor

cooling fan

Basic parameter for 400hz spindle

Set p0.03=400，p0.04=400，p0.06=400，p2.02=400

( Note ：This is to match the basic parameters of the 400hz spindle, do not need to set other parameters can be connected）

Basic parameter for 3 phase 50/60Hz motor

Set p0.03=50/60, p0.04=50/60, p0.06=50/60，p2.02=50/60

( Note ：The default setting of the VFD is 50hz, which can be directly connected to the motor for driving)

DC cooling fan/Aluminum base

  • DC cooling fan low noise, large air volume help vfd heat dissipation, improve product stability
  • Aluminum base: This ensures the stability of the product and increases the heat dissipation capacity of the fan

keyboard

Control panel

  • UP: Progressively increase data or function codes.
  • DOWN: Progressively decrease data or function codes.
  • DATE/SET: Progressively enter menu and confirm parameters
  • PRG/ESC: enter or eacape from the first level menu
  • SHIFT: Switch monitoring parameters at monitoring state, at secondary menu, move data box to process editing position.
  • QUICK/JOG:Determined by function code P7.03=(0:Display stautsa switching,1:jog operation,2:switch between forward and reverse,3:Clear the up/down terminals settings,4:Quick debugging mode)

Multiple terminals

Multiple terminals

  • Unlike other inexpensive VFDS, this VFD has two sets of terminal functions,Rich of digital and analogy control terminals for versitile control,optional MODBUS (RS485) extension,diversified parameter setting.
  • Adopt DSP vector control to enable motor to achieve high torque in low speed rotati
  • Support external potentiometer for remote control.（"COM" and "S1" terminal connection your controller switch. then set P0.01=1）
  • supports mcah3 function and RS-485 communication
  • Support brake resistance installation function, faster motor braking
