ASDA-A3
You can use ASDA-Soft to create the E-Cam curve. Click E-CAM in the software function list
and the E-CAM Editor appears, as shown in Figure 7.3.4.2.
In the first page of the editing window, select the method to create the E-Cam curve table. There
are seven options, [Manual], [Speed Fitting], [Rotary Shear - W/O Sync. Zone], [Rotary Shear -
Fixed Sync. Zone], [Rotary Shear - Adjustable Sync. Zone], [Cubic Curve], and [Rotary Shear -
Printing Machine].
Manual
When you use other software to create the table, the software presents the final results with
position data and then imports these data to the table to complete the E-Cam curve. As the
example shown in Figure 7.3.4.1, the mechanical cams can be replaced by E-Cams. It creates
the E-Cam curve by using the angles of the mechanical cams corresponding to the distances
between the cam shaft and edge, which is to establish the correlation of the angles and slave
axis positions. The setting interface for manually creating E-Cam tables in ASDA-Soft is shown
in Figure 7.3.4.3. The following illustrates the steps to manually create the table:
Set the E-Cam segment number: an E-Cam can be divided into up to 720 segments (721
1.
points). For a 360-degree cycle, every 0.5 degrees corresponds to a slave axis position.
The more the points, the higher the resolution and the more delicate the curve.
Appropriately allocate the resources for the curve resolution and data array to set the E-
Cam segment number.
