Punch control

The punch operation is conducted by transmitting the rotation of the punch motor (M4) [4] to the eccentric cam
[6] by the punch clutch (CL1) [3] and reciprocating the punch edges [8] connected to the cam holder [1] once.
M4 rotates clockwise from the view of the rear. M4 drives the eccentric cam and performs the punch operation
when CL1 turns ON. M4 keeps rotating during the punch operation.
The punch home sensor (PS6) [5] detects the home position of the punch edges.
