Manual
If the E-Cam table is created with other software, it is also presented in the form
of points and be imported into the table to complete the cam curve. As shown in
Figure 176
, the E-Cam curve is created based on the cam curve-to-edge distance
corresponding to each angle of the mechanical cam, which means the relationship
between the angle and the slave axis position. The KNX5100C E-Cam table
manual creation interface is shown in Figure 178
. The following are the steps to
manually create the table:
1. Set the number of E-Cam segments.
A single cam can be divided into up to 720 segments (721 points). For a
period of 360 degrees, that means every 0.5 degrees corresponds to a slave
axis position. The more points, the higher the resolution and more
accurate the curve. To select the most suitable number of segments,
measure the resolution of the curve and the resource usage of the data
array.
2. When the number of E-Cam segments is set, click Create Table.
The software automatically divides 360 degrees into the table by dividing
the number of segments. When the number of segments is set to n points,
the table generates n+1 splits.
3. Fill in the position of the slave axis.
