4.2.1 Data format of motion profile data
For data import with the Cam Loader, the motion profile data must be available as an ASCII
file with the ending *.txt.
[ Each line contains the x and y position of a point.
[ Comma and point are allowed as decimal symbols.
[ Between the two position data there may only be one or several separators (spaces or
tab characters).
[ After the two position data you can add a comment after at least one separator and
two slashes ("//") (option).
[ Space lines between the position data are allowed.
[ The points must be entered in ascending order of the x positions.
[ Each file must contain at least two interpolation points.
Example:
Example:
The 3rd column contains the acceleration values in Nm referenced to the motor.

Note!
If a syntax error occurs during the data import the number of the line in which
the syntax error has occurred will be indicated in the optional error message!
10.0 20.0 // point 1
20.0 30.0 // point 2
33.3 44.4 // point 3
55.5 66.6 // point 4
77.7 88.8 // point 5

Note!
Servo PLC and ECSxA... allow for specifying an acceleration profile.
• If a profile is specified, then this acceleration profile will be used.
• If no profile is specified, the second derivative is formed from the curve for the
acceleration profile.
10.0 20.0 1.0 // point 1
