Cam axis current
value per cycle
• 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.

+10
Cam axis current feed
value
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.)

(4) Specify the device No. with (D) to an even number.
The specified device stores the cam position calculation result as shown below
when the calculation is completed.
• Cam axis current feed value calculation:
The cam axis current feed value that is calculated within the following range is
stored.
