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.
