same as motor driver. The modes vs. signal type of OUT and DIR
pins are listed in the table below:
Single Pulse Output Mode (OUT/DIR Mode)
In this mode, the OUT pin is for outputing command pulse
chain. The numbers of OUT pulse represent distance in pulse.
The frequency of the OUT pulse represents speed in pulse per
second. The DIR signal represents command direction of posi-
tive (+) or negative (-). The diagrams below show the output
waveform. It is possible to set the polarity of the pulse chain.
Pulse mode = 0: ( OUT pin normally high )
Pulse mode = 1: ( OUT pin normally low )
Pulse mode = 2: ( OUT pin normally high )
Pulse mode = 3: ( OUT pin normally low )
