Working Mode:1. Normal Mode 1: S1 start stop button, S2 forward and reverse button, W2 potentiometer speed control. If limit reversal is required, two limit switches can be connected to the P3 pin, and the motor motion shaft is mounted with contacts, so that the motor will reciprocate within the stroke between the two limit switches.2. Normal Mode 2: S1 forwards the start button, S2 reverses the start button, press any button to stop. W2 potentiometer speed regulation. If the limit stop is required, two limit switches can be connected to the P3 pin, so that the motor will stop moving when it touches the limit switch, and the motor will reverse after the opposite button is clicked.3. Jog Mode: S1 presses the forward rotation, releases the stop, S2 presses the reverse rotation, releases the stop, and the W2 potentiometer adjusts the speed. If a limit stop is required, the upper limit switch can be connected to P3.4. Automatic Round-trip Mode: S1 starts and stops, S2 is reversed, W2 potentiometer speeds, and W1 potentiometer adjusts the automatic round-trip steps. After starting, the motor automatically runs back and forth within the number of steps adjusted by W1Voltage Range: DC 5V-12VRated Current: Less than or equal to 800mAPower Reverse Connection Protection: yesOver-current Protection: yesOverheat Protection: yesFine workmanship and good performance.Easy to use.Long service life.Color: greenMaterial: metal + PCPackage Contents: 1* Motor Driver Board1* DuPont lineOnly 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.
