12.1.13 Cam axis position at cam control switching
The cam axis position is determined by the positional relationship of three values of "Cam axis one cycle
current value", "Cam axis standard position" and "Cam axis feed current value". When the control has been
switched to the cam control (CAMC (Cam control command) is on), defining the positions of two of these
values restores the position of the remaining one value.
Cam axis one cycle current value
Cam axis feed current value
Cam standard position
The following table lists the parameters required to be set for the cam axis position restoration. Refer to
section 12.1.7 (3) for the settings.

Restoration
processing details
0: Cam axis one
cycle current
value
(Note) (Used as the search
starting point of cam
pattern.)
"Cam axis one cycle
current value" is
restored based on
"Cam standard
position" and "Cam
axis feed current
value".
1: Cam standard
position
(Note)
"Cam standard
position" is restored
based on "Cam axis
one cycle current
value" and "Cam axis
feed current value".
2: Cam axis feed
current value
(Note) (Note)
"Cam axis feed
current value" is
restored based on
"Cam axis one cycle
current value" and
"Cam standard
position".
: Required
Note. Set this parameter when [Cam control data No. 3] is set to "1".
