APPLICATION NOTE
OPERATING PRINCIPALS FOR PRACTISPIN
STEPPER MOTOR MOTION CONTROL

1 REQUIREMENTS
In operating a stepper motor system one of the most common requirements will be to execute
a relative move. The move will usually be specified as a fixed number of basic motor steps in
the clockwise or counter-clockwise direction. It is common practice to execute this move along
a trapezoidal shaped velocity vs. time profile.
This profile is determined by the number of steps to be moved and the required accel, decel,
and peak speed. Very often system designers require that a move be made in the shortest
time pos
