3.3.3 EN Digital Input
While the STEP and DIR inputs are designed for high-speed digital input operation, the Enable
(EN) input is designed for low speed digital input operation between 5 and 24 volts.
Note: If current is flowing into or out of an input, the logic state of that input is low or
closed. If no current is flowing, or the input is not connected, the logic state is high or
open.
The diagrams below show how to connect the EN input to various commonly used devices.
