Punch Selection and Firing
[A]: Punch Drive Motor (M24)
[B]: Punch Encoder Wheel
[C]: Punch Encoder Sensor (S24)
[D]: Punch HP Sensor (S23)
The punch drive motor (M24) [A] turns the small, notched encoder wheel [B] through the gap in
the punch encoder sensor [C] (S24). The sensor output is used to control the punch timing.
The timing for 2-hole punching [E] is different from 3-hole punching [F].
When the punch unit is at the punching position, the punch motor turns until the encoder detects
the starting position for 2-hole or 3-hole punching.
