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.
