stepper motor driver

YARAK Drive Product Number Code: 1. Series 2. Phase 2S 2 Phase 3. Output current (MAX) 30 the largest output current 3A 15 the largest output current 1.5A 4. Input Voltage (MAX) 60 the largest input voltage 60V 5. microstep M fixed microstep 25 S microstep 2,4,8,16,32,64 selectable N microstep 5,10,25,50 selectable 0 microstep 25,100 selectable Remark: please refer to manual instruction about the detailed functions. About inputting Please use voltage less or equal 24V. When voltage ≤5V, no need external resistance R1. If voltage over 5V, please connect external resistance R1, and keep the driver input termial under 5V.When pulse signal stopping, please disconnect the signal input terminal.When on double pulse signal working, please do not use CW and CCW concurrent connections.Please convert running direction after pulse signal stopping.No need to connect EN terminal on normal conditions.
