8. Sequence Chart of Control Signals
In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some rules, shown as
following diagram:
Remark:
(1) t1: ENA must be ahead of DIR by at least 500ms. Usually, ENA+ and ENA- are NC (no connected). See
"Connector P1 Configurations" for more information.
(2) t2: DIR must be ahead of PUL effective edge by 5us to ensure correct direction.
(3) t3: Pulse width not less than 1us @ 5V, 2.5us @ 24V, these widths are based on a 50% duty cycle. If it is
greater or less than 50%, the width time is required to be wider.
9. Fault Protections
To improve reliability, the drive incorporates some built-in protection features.
