Simple cam function
CAUTION
• Note that the number of write times to the Flash-ROM where the cam data is stored is limited to approximately 10000. If the total number of write times
exceeds 10000, the servo amplifier may malfunction when the Flash-ROM reaches the end of its useful life.
• The simple cam function can be used with the point table method.
• When [AL. F5.2 Cam data miswriting warning] occurs during cam data writing, set [Pr. PT34] to "5010" to
initialize the cam data.
• Simple cam function is not compatible with infinite feed function. When using the infinite feed function,
configure the incremental system.
• When using the simple cam function, execute operation so that the machine speed of the input axis is equal
to or less than "[Cam control data No. 48 - Cam axis length per cycle] × 1/2 × 1000 [command unit/s]".
• When [Cam control data No. 30] is set to "1", the unit of Cam axis length per cycle is changed to [mm],
[inch], [degree], or [pulse] with the setting of [Pr. PT01]. When [Cam control data No. 30] is set to "2", the
unit of Cam axis length per cycle is changed to [mm], [inch], [degree], or [pulse] with the setting of [Cam
control data No. 14].
• The touch probe function cannot be used when "Simple cam function selection" in [Pr. PT35] is set to "2" or
"3" and cam position compensation by touch probe is enabled.
Outline of simple cam function
Simple cam function enables synchronous control by using software instead of controlling mechanically with cam.
The following shows a path when the cam as follows is used and the input axis is rotated once.

In the simple cam function, setting cam data and cam control data enables synchronous control with an input axis
(synchronous encoder input or point table command) with a start of positioning.
