Figure 5 shows a timing diagram for the control of the phases in a stepper motor control
where the steps and the step rate are controlled by clocks. The variation of the clock rate or
the variation of the time between the two clock pulses determines the step rate. Change in
the step rate determines the acceleration, deceleration, and the slew rate in a given motion
profile.
Figure 6 shows a typical trapezoidal motion profile. In the acceleration mode the step rate
starts slowly and as the motion progresses the step rate increases according to a step rate
table until it reaches the slew rate. At the slew rate the step rate is fixed and the period of
the step clocks is constant. At the end of the slew rate the deceleration starts. In this part of
the profile the step rate decreases according to a step rate table until the last step. The
repeatability and accuracy of the step clocks in a stepper motor plays a major role in the
stepper motor performance.
