Chapter 7 Motion Control Functions
Function of E-Cam Curve
E-Cam Curve Content
E-Cam curve saves the position data of slave axis (user unit is
PUU).
If E-Cam is divided into N parts, it means that total N+1
points are recorded in the data array. This is because the
position of the first point (0°) and the position of the last
point (360°) are not the same.
1. When the positions of 0° and 360° are the same:
2. When the positions of 0° and 360° are not the same:
Suppose that:
1. When the positions of 0° and 360° are the same:
It indicates that the position of slave axis will return to
home after E-Cam rotates 360° (one revolution).
2. When the positions of 0° and 360° are not the same:
It indicates that the position of slave axis will not return
to home after E-Cam rotates 360° (one revolution).
