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