Pin Function

Details

+Vdc

Power supply, 20~50 Vdc, Including voltage   fluctuation and EMF voltage.

GND

Power Ground.

PUL+

   Pulse   signal: In single pulse (pulse/direction) mode, this input represents pulse signal,   each rising or falling edge active (software configurable); 4-5V

when PUL-HIGH, 0-0.5V when PUL-LOW. In   double pulse mode (pulse/pulse) ,this input represents clockwise (CW) pulseactive   both at high level and low level (software configurable). For reliable   response, pulse width should be longer than 2.5μs. Series connect resistors   for current-limiting when +12V or +24V used. The same as DIR and ENA signals.

PUL-

DIR+

DIR signal: In single-pulse mode, this   signal has low/high voltage levels,

representing two directions of motor   rotation; in double-pulse mode (software

configurable), this signal is counter-clock   (CCW) pulseactive both at high

level and low level (software   configurable). For reliable motion response, DIR

signal should be ahead of PUL signal by 5μs   at least. 4-5V when DIR-HIGH,

0-0.5V when DIR-LOW. Please note that   rotation direction is also related to

motor-Driver wiring match. Exchanging the   connection of two wires for a coil

to the Driver will reverse motion   direction. 

DIR-

ENA+

ENA Enable signal: This signal is used for   enabling/disabling the Driver. High level(NPN control signal, PNP and   Differential control signals are on the contrary,namely Low level for   enabling.) for enabling the Driver and low level for disabling the Driver.   Usually left UNCONNECTED (ENABLED).
