5.4 L_CamGetAxisData - reading out machine parameters from cam data
This FB reads out the machine parameters of the axis selected via the input dnAxisNumber from the
cam data and via the output AxisData provides them to subsequent FBs requiring these data for in-
ternal calculations (e. g. master value integrators, FBs for stretching/compression and other FBs for
processing cam data).
• If it is used within curve applications, the FB at least has to be instanced twice:
• Instance 1 for the 1-measuring system (e. g. the measuring system of the x axis)
• Instance 2 for the 2-measuring system (e. g. the measuring system of the y axis)
• Further instances for other measuring systems available (e. g. characteristic) are then to be ad-
ded according to the application.
Inputs
Function library: LenzeCam FB only permissible for firmware from V3.0 onwards!
Runtime software licence:  Motion Control HighLevel  Motion Control TopLevel

Note!
In order to enable the FB to read out machine parameters from a measuring system, the
corresponding measuring system must be used in the »Cam Manager« at least once in a
curve, cam, or position marker track!
Access to the machine parameters of the drive/motor
The machine parameters of the drive/motor via the output DI_AxisData of
the LS_DriveInterface SB are provided to other function blocks requiring these data for
internal calculations.
Identifier/data type Information/possible settings
