Outside cam axis
current value per cycle
(Initial setting) range
The synchronous parameter "[Pr.468]
Cam axis current value per cycle (Initial
setting)" is set other than 0 to (Cam axis
length per cycle - 1).
Synchronous control
does not start.
Set within the range of 0 to (Cam axis
length per cycle - 1).

Cam axis current value
per cycle restoration
disable
Cam axis current value per cycle
corresponding to the feed current value
at synchronous control start could not
be restored when the synchronous
parameter "[Pr.462] Cam axis position
restoration object" was "0: Cam axis
current value per cycle restoration".
(Occurs in reciprocated cam pattern)
• Start synchronous control after moving
the feed current value as to fit within
the stroke of two-way operation cam
pattern.
• Set the cam reference position as to fit
within the stroke of two-way operation
cam pattern.

(301h)
Cam axis feed current
value restoration
disable
Restoration could not be completed
when the synchronous parameter
"[Pr.462] Cam axis position restoration
object" was "2: Cam axis feed current
value restoration", because the
difference between the restored cam
axis feed current value and the feed
current value at synchronous control
start (pulse command unit) was larger
than the servo parameter "In-position
range".
• Start synchronous control after
calculating the cam axis feed current
value to be restored, using the cam
position calculation function, and
moving the feed current value.
• Set a larger setting value for the servo
parameter "In-position range", if the
current value is extremely small (such
as 0).
