input represents pulse signal, effective for each rising or falling edge(setby inside jumpers in JP1); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. Indoublepulse mode (pulse/pulse) , this input represents clockwise(CW)pulse,effective for high level or low level (set by inside jumpers inJP1).For reliable response, pulse width should be longer than 1.5μs. Seriesconnectresistors for current-limiting when +12V or +24V used.

M860H Stepper Motor Driver’s Microstep and Current

The drives uses an 8 bits DIP switch to set stepper motor resolution andmotoroperating current, as shown below:

Dynamic Current(1/2/3) Microstep Resolution(6/7/8)
