2.2.3 Punch Operation

0006-6517
The hole puncher is driven by the punch motor (M1), and its position is monitored by the
punch home position sensor (SR2).
The hole puncher makes a single round-trip movement (punching) as the punch shaft rotates
180 deg from home position.
In the case of a 2-or-3 hole type, the half sector of the punch shaft is used when punching 2
holes while the half sector on the opposite side is used when punching 3 holes as instructed
by the host machine.
