ITEM NAME:Stepper Motor Drive Simple Controller Speed Forward and Reverse Control Pul Y3S4 Stepper Motor Drive Simple Controller Speed Forward and Reverse Control Pul Y3S4 When the controller generates a pulse frequency signal, it can be used as a signal for the stepper driver. Drivers are also required to control the stepper motor. This simple controller + Stepper motor driver + Stepper motor + DC power supply can form a simple control platform. The controller can generate a pulse frequency signal, it can also be generated. PWM Signal pulse duration. There is a bouncing needle on the board., You can set options Select, the default setting should generate a pulse frequency signal. REQ It generates a pulse frequency. When the controller generates a frequency pulse signal, has a high, low frequency signal can be selected by a jumping needle, the frequency parameters are approximately: High: 5.8 kHz-127 kHz V: 590 Hz-15.8 kHz Low: 82 Hz-2.3 kHz, Frequency measurement: the number of available negative terminals (GND) two ports. Power supply 2 Power input group, 2 groups A can only be connected to a group of power sources. the recommended power supply is 15 V. receive2 bit terminal power supply, neither positive nor negative, we must accept the opposite .. One group is a power supply connected to DC.15-160VDC, the recommended working voltage15-80VDCAll right. The other group is5-12VDC. when used in conjunction with the driver, it is recommended that minimum12V be used, do not use 5V power, 5V not too long, positive power supply "5-12 Venter", negative power supply "common cathode end". Connection instructions: Wiring each connection port, instructions for the silk screen next to the terminals. It can be connected to a step driver using a regular yin or common yang. Colour: green Material: plastic Size: 73*51*37MM Package Contents: 1 x Stepper motor drive controller
