AIN / VR:Analog input.This connector can connect to three kinds offor speed governing. When using 0-5V/0-10V voltage speed governing or 4-20mA currentto speed governing, need to set 4-digit DIP switch. 1)Potentiometer Speed Governing:5V, AIN/VR, GND connect respectively to three pins of a 10kR potentiometer to manually control speed; At the same time, the 4-digit DIP switch is set as 0~5V - PWM(SW1 - ON, SW2 - OFF, SW3-OFF, SW4-ON) SW3-OFF; SW4-ON 2) :Input 0-5V or 0-10V voltagefor speed governing.AIN/VR connects to voltage , GND connects to ground. At the same time 4-digit DIP switch is set as 0~5V - PWM(SW1 - ON, SW2 - OFF, SW3-OFF, SW4-ON SW3-OFF; SW4-ON; No resistor is needed for 0-5V voltageinput, directly connect to AIN/VR &GND Two resistors should be added for 0-10V voltageinput as wiring in the diagram below: 3)Input 4-20mAfor speed governing.AIN/VR connects to current , GND connects to ground.At the same time, 4-digit DIP switch is set as 4-20MA - PWM (SW1-OFF, SW2-ON, SW3-OFF, SW4-ON) SW3-OFF; SW4-ON GND: common ground (hot ground, do not touch when power on) ON/OFF: Motor ON/OFFit can connect to an external switch.When not connected to GND, motor is on; when connected to GND, motor is off.The external ON/OFF switch connect respectively to ON/OFF and GND. 5V:Power supply 5V output pin.
