Basic settings require to use the simple cam
function
Item Setting Setting value
Operation mode
selection ([Pr.
PA01]) Select "Point table
method". "1006"
Simple cam
function setting
([Pr. PT35]) Enable the simple cam
function. "_ 1 _ _"
Device setting Assign CAMC (Cam
control command input),
CAMS (Output in cam
control), and CI0 to CI3
(Cam No. selection 0 to 3)
with I/O setting parameters
([Pr. PD_ _ ]). Refer to
section
7.2.4.
When the conveyor axis (main axis) feeds a
sheet by the set length, the rotary knife makes
one rotation (360 degrees) to cut the sheet. Set
the following items as follows.
Item Setting Setting value
Cam axis one

Cam stroke
amount ([Cam
control data No.
51]) Set the rotation amount
per rotation in "degree".
360.000
Synchronous
encoder axis unit
([Cam control
data No. 14]) Set the unit of the sheet
length.
0 (mm)
Unit of rotary
knife axis ([Pr.
PT01]) Set "degree" as the unit of
position data.

encoder following function.
Item Setting Setting value
Main shaft input
axis selection
([Cam control
data No. 30]) Select the synchronous
encoder axis. 2
