Pwm Speed Controller Stepper Motor Drive Simple Controller

1. When the controller generates a pulse frequency signal, it can be supplied to the stepper driver as a signal. If you want to control the stepper motor, it must also be equipped with a driver. The controller can generate pulse frequency signal and PWM pulse width signal. There is a jumper on the board, which can be set and selected. By default, it is set to generate pulse frequency signals. REQ is to generate a pulse frequency signal PWM is to generate PWM signal2. When the controller generates a pulse frequency signal, there are three frequency signals of high, medium and low, which can be selected by the jumper. The frequency parameters are about: High: 5.8KHZ-127KHZ Middle: 590HZ-15.8KHZ Low: 82HZ-2.3KHZ, Frequency measurement: PUL and common cathode (GND) ports can be measured.3. There are 2 groups of power input for power supply, and 2 groups only need to be connected to one group of power supplies. It is recommended to use a power supply above 15V. Connect to the power supply of the 2-position terminal, and do not reverse the positive and negative. One group is the power supply connected to DC 15-160VDC, and the recommended working voltage is 15-80VDC. The other group is 5-12VDC.4. When used with the driver, it is recommended to use a minimum of 12V, do not use a 5V power supply for power supply, it is not too much at 5V, the power supply is connected to 5-12V input, and the negative power supply is connected to common cathode.5. Controller: Driver; PUL: pulse negative terminal (PUL-); DIR: Direction Negative (DIR-); ENA: Enable negative terminal (EN-); Common anode terminal: common terminal (COM or +5V or connect to the three ports of PUL+DIR+EN+ at the same time)Wiring instructions: for the wiring of each wiring port, there are silkscreen instructions next to the terminals. Common cathode or common anode can be connected to the stepper motor driver. 5-12V power supply is positive: the positive terminal of 12V power supply is generally empty. It is recommended to use a power supply above 15V for power supply. for example: common anode wiring with the driver, if it is driven by 6 signal lines, the + of 3 signals The 5V common terminal should be connected in parallel to form a line, all connected to the common anode terminalNote that if you want to use the start or stop function, the ENA enable terminal on the controller must be connected to the driver with a common cathode or a common anode2. The forward and reverse rotation and start and stop of the motor can be controlled by pressing the buttons.3. The speed of the motor can be controlled by adjusting the potentiometer to change the frequency.4. The switch for forward and reverse rotation and start and stop of the old motor is an ordinary switch with self-locking.Model Number: PWM ControllerModel Number: Stepping motor drive controllerMotor Type: DC Motorcolor:GreenMaterial:PCBsize:73 x 51 x 37MMPackage Contents:1 x PWM Speed ControllerOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
