Remark:
(1) t1: ENA must be ahead of DIR by at least 5
μ
s. Usually, ENA+ and ENA- are NC (not
connected). See
“
Connector P1 Configurations
”
for more information.
(2) t2: DIR must be ahead of PUL effective edge by at least 5
μ
s to ensure correct direction;
(3) t3: Pulse width not less than 1.5
μ
s;
(4) t4: Low level width not less than 1.5

Wiring Notes
In order to improve anti-interference performance of the driver, it is recommended to use
twisted pair shield cable.
To prevent noise incurred in pulse/dir signal, pulse/direction signal wires and motor wires
should not be tied up together. It is better to separate them by at least 10 cm, otherwise the
disturbing signals generated by motor will easily disturb pulse direction signals, causing
motor position error, system instability and other failures.
