When the drive plate is connected by the cathode, what is the signal to be accessed at the pulse signal?
Pulse width refers to the width of the received pulse signal, generally only the smallest, because the width of the controller pulse width, the more able to receive the signal. So only the minimum pulse width is allowed by the drive,
When driving the common negative connection method, the signal at the end of the pulse signal should be connected to the high level, and the common end of the COM side is connected to the 0V.The general pulse width is greater than 1US microseconds and is recommended to be greater than 2 microseconds
Like Shanshe stepper motor driver MD-2522, MD-2545, MD-2778, MD-2208, MD-3778, MD-3208, step pulse minimum value is 250ns (NS), the direction of the signal pulse width of the minimum value is 50uS, this is the current (subtle) drive in the industry. This is the minimum value and for the Yin, Yang, differential method not too much.
