Pin Name
Descriptions
PUL(+5~24V)
Pulse control signal, falling edge is valid. For reliable response,
the pulse width should be greater than 2.5µs. PUL voltage range is
+5V~+24V.
PUL-(PUL)
DIR(+5~24V)
This signal can modify the motor direction. In order to ensure the
reliability of the motor, the DIR signal should be established at
least 5µs ahead of the PUL signal. The initial running direction of
the motor is related to the wiring sequence of the motor. DIR
voltage range is +5V~+24V.
DIR-(DIR)
ENA(+5~24V)
The ENA signal is used to enable/disable. When ENA is OFF, the
driver is enabled; When ON, the driver is disable. Usually, the
wirings are idle and the motor is enabled. ENA voltage range is
+5V~+24V.
ENA-(ENA)
