2X Stepper Motor Drive Simple Controller Speed Forward And Reverse Control Pulse Generation PWM Generation Controller 2X Stepper Motor Drive Simple Controller Speed Forward And Reverse Control Pulse Generation PWM Generation Controller 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 kHzV: 590 Hz-15.8 kHzLow: 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 ed 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 ed 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 ion port, instructions for the silk screen next to the terminals. It can be ed to a step driver using a regular yin or common yang.Colour: greenMaterial: plasticSize: 73*51*37MMPackage Contents:2 x Stepper motor drive 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. The measurement allowed error is /- 1-3cm.
