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.)
