Description: This controller can generate PWM signal functions, there is jumper on the board, you can set the default selection provided in the pulse frequency signal. Features: This module is supplied as a stepper drive signal. To control the stepper motor, but also needs to have a drive to use. The controller has high, medium and low, a total of three types of frequency signals can be used to select jumpers. The measurement frequency can be PUL and common cathode terminals (GND) two ports. PUL and PUL- pulsating positive and negative; EN and EN- are to enable positive and negative terminals; DIR and DIR- are positive and negative direction. These six lines are connected to control the appropriate pulse, direction, so six ports are possible. Power supply: 15-160VDC or 5-12VDC. If you use 5-12 VDC power supply, the positive end connect the DC 5-12V input, the negative end connect the end of the common cathode. Forward and backward motor can be controlled by pressing the key. The motor speed can be controlled by adjusting the potentiometer frequency. . MOTOR CONTROLLER SIGNAL PWM STEP GENERATOR Specification: Supply voltage: 15-160 V / 5-12 V.
