Setting example
When the sheet length is 200.0 mm, the circumferential length of the rotary knife axis (synchronous axis length) is 600.0 mm,
and the sheet synchronous width is 10.0 mm, set the following items as follows.
Basic settings required to use the simple cam function
When the conveyor axis (main axis) feeds a sheet by the set length, the rotary knife makes one rotation (600 mm) to cut the
sheet. Set the following items as follows.
Set the following items as follows to use the encoder following function.
