Ena-

This signal is used for enabling/disabling the driver. Active-high for enabling the driver (optical-isolation is not through), Active-low for disabling the driver (optical-isolation is through).

Dir-

This Active-high/low signal is used for determining the rotate direction of motor. Please note that rotation direction is also related to the connection of motor wires.

Dir+

Pul-

One step ahead when the pulse rising edge is active. Step distance is subject to the micro-step.
