11.13.3.3 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. Except for the last

interpolation point, all interpolation points of an electronic cam can be changed via the parameter

access.

• If the cam data are provided with an access protection, the user password has to be entered in

C02900

first.

Access protection

( 555)

From software version V4.0 onwards

, 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 the »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.

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.

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.

From software version V4.0 onwards

, 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" device command.
