Leadshine DM Series - Connections to Control Signal; Single-Ended Open-Collector Signal Connections

Digital Stepper Drive Hardware Installation Manual
Remark:
a) ENA must be ahead of DIR by at least 5us. Usually, ENA+ and ENA- are NC (not connected).
b) DIR must be ahead of PUL active edge by 5us to ensure correct direction;
c) Pulse width not less than t3;
d) Low level width not less than t4.

5. Connections to Control Signal
Most of the DM stepper drives can accept both differential and single-ended inputs (including open-collector and PNP output). Some
only accept the single-ended inputs due to space limit
