Get PWM Stepper Motor Driver Simple Controller Speed Controller Forward and Reverse Control Pulse Generation Feature: Product name: simple controller Model: CW-S01 It can generate PWM signal. There is a jumper on the board, which can be set and selected. By default, it is set to generate pulse frequency signal. Product Manual: 1. When the controller generates a pulse frequency signal, it can supply a stepper driver as a signal. To control the stepper motor, it must be equipped with a driver. (This simple controller + stepper driver + stepper motor + DC power supply can form a simple control platform.) 2. The controller can generate a pulse frequency signal or a PWM pulse width signal. There is a jumper on the board, which can be set and selected. By default, they are set to generate pulse frequency signals. REQ is to generate pulse frequency signal PWM is to generate PWM signal 3. When the controller generates a pulse frequency signal, there are three types of high, medium and low...
