PUL +,PUL- 

Pulse signal, PUL+ is the positive end of pulses    input pin 

                  PUL- is the negative end of pulse  input pin 

 

DIR+,DIR- 

DIR signal: DIR+ is the positive end of direction input pin 

                 DIR- is the negative end of direction input pin 

ENBL+ 

  

Enable signal:    ENBL+ is the positive end of direction input pin. This signal is used for 
enabling/disabling the driver. High level for enabling the driver and low level for disabling the 
driver. 

ENBL- 

ENBL- is the negative end of direction input pin. Usually left unconnected (enabled)
