show the output waveform. It is possible to set the polarity of
the pulse chain.
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 dia-
