In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as following
diagram:
Figure 8: Sequence chart of control signals
Remark:
a)
t1: ENA must be ahead of DIR by at least 500ms. Usually, ENA+ and ENA- are NC (not connected). See
“Connector P1 Configurations” for more information.
b)
t2: DIR must be ahead of PUL effective edge by 5us to ensure correct direction;
c)
t3: Pulse width not less than 2.5us;
d)
t4: Low level width not less than 2.5us.
