Pulse and direction signals

Pulse and direction, step and direction or pulse train refers to digital signaling type used in position control. Pulse & dir is famous from stepping motor drives but it also can be used in many servo drives as position or velocity reference signal.

Principle

Pulse & dir contains two digital signal lines:

  • Pulse - a signal that will control motion distance & speed
  • Direction - a signal that will control direction of motion

Pulse has constant distance increment, i.e. 1/1000 of revolution. So to rotate motor one revolution it takes 1000 pulses. To rotate in reverse direction, direction signal state is changed.
