Delta RMC151 - Manual (Page 163)

3 Controller Features
When determining the curve points, keep in mind that the axis that follows the curve
must be at the starting Y-axis position before the Curve Start command is issued. That
is, the first point is where the axis must be at the start.
2. Create the Curve Data in the Variable Table
Several different curve data formats are available, as described in Curve Data Formats.
This procedure uses the simplest format: Single Curve - Evenly-Spaced Points:
Offset Description
0 Curve Status (set to 0, the RMC will change this value)
1 Curve Format (0 = Single Curve - Evenly-Spaced)
2 Number Points
3 Interpolation Options (set to 0 for none)
4 Point 0 x value (set to 0 for time, or the starting master x position for
master-based)
5 x interval (distance between x points)
6 y0 (first y position)
7 y1 (second y position)
: :
5+n y(n-1), n = number of points (nth y position)
Place the curve data anywhere in the Variable Table. The curve data for this example
starts at F56:10. Adding descriptions helps keep track of what the data is for. By
entering this data into the initial values of the Variable Table, the curve data can be
saved to flash. Notice that the curve in the Curve Store cannot be saved to Flash, but
the curve data in the initial values in the Variable Table can be. Optionally, you can set
all the curve data variables to Retained, and they will be remembered between power
cycles without requiring a Flash update.
