Stepper Controller Pinout

Shimai Robot stepper controller is divided into open loop and closed-loop types. The main application is stepper motor linear actuator, stepper motor linear cylinder, stepper motorized linear stage, metering peristaltic pump, special motion control module and other applications. The stepper controller has buttons and digital user interface. Internal parameters can be set without an external physical switch.
The external drive can use the external pulse as the traditional drive Pulse and Direction mode, or it can use the internal pulse function to realize the displacement control and speed control Potentiometer (POT) on board. If the closed-loop drive is used, the drive will handle the displacement or protection after the stall.
