Setting data Description
(S1) Cam position calculation: Cam No. (0 to 1024)
(S2) Start device No. which stores the cam position calculation control data
(D) Device No. which stores the cam position calculation result
Processing details
• For the cam No. data specified with (S1), the cam axis current feed value or the cam axis current value per cycle is
calculated from the cam position calculation control data specified with (S2), and the value is output to the device specified
with (D).
• Specify the cam No. to perform the cam position calculation with (S1). When cam No. 0 is specified, the cam position is
calculated as the linear cam. For cam No.1 to 1024, the cam position is calculated with the cam data on the cam open area.
• The device No. specified with (S2) should be an even number. Set the cam position calculation control data in the specified
device as follows.

Description
Specify the cam axis current feed value calculation/cam axis current
value per cycle calculation
Set 0.
Set the cam stroke amount for the cam position calculation.
Set the cam axis length per cycle for the cam position calculation.
Set the cam reference position for the cam position calculation.
• Set the cam axis current value per cycle for the cam position
calculation when calculating the cam axis current feed value.
• Set the cam axis current value per cycle as the starting point to
search when calculating the cam axis current value per cycle and the
cam position.
Set the cam axis current feed value for the cam position calculation
when calculating the cam axis current value per cycle. (This is not used
when the cam position calculation type is set to the cam axis current
feed value calculation.)
