Data setting area:

Resolution
: Users can set the number of data points required in the electronic cam chart. The
number of data points must be in the range of 10 to 2047.

Velocity
: The maximum speed of the slave axis and the minimum speed of the slave axis are
shown in this section. They are calculated by the system according to the data related
to displacement. Users can change the maximum speed of the slave axis and the
minimum speed of the slave axis by themselves.

Acc
: The maximum acceleration of the slave axis and the minimum acceleration of the slave
axis are shown in this section. They are calculated by the system according to the data
related to displacement. Users can change the maximum acceleration of the slave axis
and the minimum acceleration of the slave axis by themselves.

Data Setting…
: The description of the relation between the master axis and the slave axis in
terms of displacement is shown in the
Data Setting
window. The displacement
resolution set in the data setting area will be brought into the
Data Setting
window after the
Data Setting
window is opened. If users click the
Apply
B-spline
checkbox in the data setting area,
B-spline
will be automatically
selected in the
Data Setting
window.

Import
: Importing the description of the relation between the master axis and the slave axis in
terms of displacement

Export
: Exporting the description of the relation between the master axis and the slave axis in
terms of displacement

Import Speed Data
: Importing the description of the relation between the master axis and the
slave axis in terms of speed
After the users click
Data Setting…
in the
CAM Chart-0
window, the
Data Setting
window will appear.
The
Data Setting
window is composed of sections. The users can set a section of a cam curve in every
section. A complete cam curve is composed of several sections. The users can set 360 sections at
most. An electronic cam cycle is composed of the sections created by the users.


Users can define the relation between the master axis and the slave axis in every section.

Master Axis
: Users can
set the displacement of the master axis.
A pulse is a unit of the
measurement for displacement. The values that the users type in the
Master Axis
(pulse)
column must be greater than 0, and must be in numerical order.

Slave Axis
: Users can set the displacement of the master axis. A pulse is a unit of the
measurement for displacement. The values that the users type in the
Slave Axis
(pulse)
column can be positive values or negative values.

CAM Curve
: The functions which can be selected are
Const Speed
,
Const Acc.
,
Single
Hypot.
,
Cycloid
, and
B-Spline
. If users click the
Apply B-spline
checkbox in the
CAM Chart-0
window,
B-spline
will be automatically selected in the
Data Setting
window.

Resolution
: Users can set the number of data points used in a section. The number of data
points must be in the range of 10 to 2047. If the users do not set resolutions for
