12.13.3.3 Changing cam data via parameterisation
If required, the cam data (motion profiles/characteristics, cams, and position markers) can be
changed via corresponding parameters if the controller is in storage mode 1.
• If the cam data are provided with an access protection, the user password has to be entered in
C02900 first.  Access protection ( 587)
• The time stamp of the cam data is updated if the cam data are changed by parameter setting.
This enables, for instance, the »Engineer» to recognise that the cam data of »Engineer« project
and those of the controller differ.

How to change an interpolation point in a curve (motion profile or characteristic):
1. Go to C02911 and set the product number of the product to be edited.
2. Go to C02920 and set the track number of the curve track to be edited.
Tip!
In
C02921 the curve type, and in C02922 the number of interpolation points of the curve
selected is shown.
3. Set the interpolation point to be edited in C02923 .
4. Change the desired parameters of the selected grid point:
• C02924 : x position
• C02925 : y position
• C02926 : Torque feedforward control value
(only in case of a motion profile with feedforward control.)

Note!
If the controller is in storage mode 2 or 3, the cam data cannot be changed via
parameterisation. All parameters for change are ineffective and set to zero.  Memory
distribution ( 586)
If the cam data of the controller have been changed by parameter setting, the
C00002 = "504: Calculate Cam Checksum" device command has to be executed
afterwards.  Calculate cam data checksum ( 141)
Then the cam data can be converted into the internal format with the "503: Calculate
Cam Data" device command or saved on the memory module in a powerfail-proof
manner with the "502: Save Cam Data" device command.  Calculate cam data ( 140) /
 Save cam data ( 138)
The changed cam data and the parameters can be saved together on the memory
module in a powerfail-proof manner with the C00002 = "11: "Save start parameters"
drive command.  Save start parameters ( 99)
