Stepping sequence generation
The phase sequence generator is a state machine that provides the phase and enable
inputs for the two bridges to drive a stepper motor in either full step or half step. Two full step
modes are possible, the normal drive mode where both phases are energized each step
and the wave drive mode where only one phase is energized at a time. The drive mode is
selected by the HALF/FULL input and the current state of the sequence generator as
described below. A rising edge of the CLOCK input advances the state machine to the next
state. The direction of rotation is set by the CW/CCW input. The RESET input resets the
state machine to state 1.
4.6
Half step mode
A HIGH logic level on the HALF/FULL input selects half step mode. Figure 18 shows the
motor current waveforms and the state diagram for the phase sequencer generator.
At start-up or after a RESET the phase sequencer is at state 1. After each clock pulse the
state changes following the sequence 1,2,3,4,5,6,7,8,… if CW/CCW is high (clockwise
movement) or 1,8,7,6,5,4,3,2,… if CW/CCW is low (counterclockwise movement).
