sents direction command of positive (+) or negative (-). This mode
is most commonly used. The diagrams below show the output
waveform. It is possible to set the polarity of the pulse chain.
Figure 4-4: Single Pulse Output Mode (OUT/DIR Mode)
Dual Pulse Output Mode (CW/CCW Mode)
In this mode, the waveform of the OUT and DIR pins represent
CW (clockwise) and CCW (counter clockwise) pulse output
respectively. Pulses output from the CW pin makes the motor
move in positive direction, whereas pulse output from the CCW
pin makes the motor move in negative direction. The following
diagram shows the output waveform of positive (+) commands
and negative (-) commands.
