PUL+(CCW+) Pulse input signal: The pulse effective edge is adjustable,default pulse rising edge is valid; In order to reliably respond to the pulse signal , the pulse width should be greater than 1.2µs.Input voltage range:3.3~28V.  Double pluse mode(under) : CCW
PUL-(CCW-)
DIR+(CW+) Direction input signal:High/low electrical level signal, in order to ensure reliable motor reversing, the direction signal should be established at least 5µs before the pulse signal.The initial running direction of the motor is related to the wiring of the motor windings. The direction of the initial running of the motor can be changed by interchanging any one-phase winding (such as A+ and A- exchange). Double pluse mode(under) : CW
