Overview of Version 1 Upgrades
Function
Electronic cam This function synchronizes the operating axis with the input axis based
(CAMBOX) on the set cam table.
The following options can be selected for the input axis: Virtual axis
present position, real axis position command value, real axis encoder
feedback input, MPG input, or sync encoder input. There are 720 cam
table points.

Advantages
Can improve design effi-
ciency because adjust-
ments are simpler than
with mechanical cams.
Operations such as posi-
tion compensation are
enabled by integrating a
virtual axis.
Time
Can be used for pur-
poses such as providing
accurate position com-
pensation by means such
as marks printed on film.
The winding width, num-
ber of windings, and pitch
can be set for individual
layers, enabling complex
traverse control.
