TITLE
1. Outline
“Electronic CAM function” has been enhanced as follows.
(1)
Extension of maximum point number of CAM profile data
In the conventional specification, the maximum point number of CAM profile data is fixed
at 2048. This specification has been improved so that the maximum point number is variable
according to tape storage length and follower axes number.
(2)
A CAM follower links with or unlinks from a CAM shaft on the fly
In the conventional specification, a CAM follower must be synchronized with a CAM shaft
during electronic CAM operation. This has been improved so that a CAM follower can join in or
cut off synchronization with a CAM shaft on the fly.
(3)
Switch a CAM shaft from “External axis + absolute pulse coder” to “imaginary axis”.
A CAM shaft can not be switched from “external axis +absolute pulse coder (external
synchronization)” to “imaginary axis (internal synchronization)” during electronic CAM operation
because the CAM follower gets a shock. This has been improved so that smooth switching is
realized by adapting the velocity just before switching as the starting velocity of imaginary axis.
Notice
When “a servo axis” is assigned to a CAM-shaft, it is not permitted to switch to imaginary axis.
(*) Hereafter, “External axis + Absolute pulse coder” is abbreviated to “External
axis”.
The following pages are newly added as “the section 23
Enhancement of Electronic CAM Function”.
