6.4.4 FB 438 MC_GetCamPoint - Reading points from the cam disk
Valid for firmware version V3.1.x of the integrated technology
Purpose
• The "MC_GetCamPoint" technology function can be used to determine the
position of a following axis to the leading axis position, based on an existing
cam disk.
• The "MC_GetCamPoint" technology function can be used to determine the
position between a following axis and the leading axis, based on an existing
cam disk.
- The same following axis positions can be entered for different leading axis
positions in the cam disk definition. Hence, the leading axis position must
be defined in closer details. This can be done at input parameter
ApproachPosition. At this input parameter, enter the assumed leading axis
position as approximate value.
• When a cam disk was configured in S7T Config using CamEdit or CamTool,
the scaling and shift defined with those tools are included when the positions
are determined. Cam disk dynamically created in RUN are never scaled or
shifted.
Any scaling or shift operations by the input parameters of the technology
function MC_CamIn are ignored when the positions are determined.
Applicable to
• Cam disks
Requirements
• The cam disk was interpolated without error (status in technology
DB 2 = interpolated.)
