encoder.
■Output axis
• Main shaft module
Name Parts Function description
Main shaft • The input axis on the main
main input side of the main shaft module.
axis • The reference position on the
main shaft.
Main shaft • The input axis on the sub side
sub input of the main shaft module.
axis • It is used to input the
compensation amount for the
position of the main shaft
main input axis.
Composite • The composite movement
main shaft amount of the main shaft
gear main input axis and the main
shaft sub input axis are
transmitted to the main shaft
gear.
Main shaft • The converting movement
gear amount after composite main
shaft gear is transmitted by
the setting gear ratio.
Main shaft • The movement amount of the
clutch main shaft is transmitted by
the clutch ON/OFF.
