Application: The controller has three types of high, medium and low frequency that can be used to select jumpers. The measurement frequency can be two ports, PUL and common cathode terminal (GND). PUL + and PUL-pulse positive and negative; EN + and EN- are used to enable positive and negative terminals; DIR + and DIR- are positive and negative directions. These six lines are connected to drive the corresponding pulse, direction, so six ports are possible. Power: 15-160VDC or 5-12VDC. If a 5-12 VDC power supply is used, the positive terminal is connected to the DC 5-12V input and the negative terminal is connected to the common cathode terminal. Press the button to control the forward and reverse of the motor. The speed of the motor can be controlled by adjusting the frequency of the potentiometer. High-quality materials: Made of high-quality materials, anti-rust, wear-resistant, corrosion-resistant, low-temperature resistant, with a certain hardness, wear resistance, a certain impact resistance, Stable, not shaking, collision is not easy to damage. Good materials can increase product life. PWM functions: This controller can generate a PWM functions, the board has a jumper, you can set the default selection provided in the pulse frequency The controller has high, medium and low total of three types of frequency can be used to select jumper. Help: High quality pulse generator, this module is provided as a stepper drive To control the stepper motor, you must also have a drive to use it.
