|
Done |
BOOL |
FALSE, TRUE |
N/A |
TRUE = the function block has successfully calculated the slave position. The slave position is available at the SlavePos output. |
|
Error |
BOOL |
FALSE, TRUE |
N/A |
TRUE = an invalid input was specified or an error occurred in the calculations. The value at the SlavePos output is undefined. |
|
ErrorID |
INT |
No range |
N/A |
Indicates the error if the Error output is set to TRUE. |

Remarks
-
- This function block starts a motion-related action and stores data for calculations and error checking.
If using a dual-core controller, see Call Function Blocks Multiple Times in the Same Cycle.
- This function block returns the slave axis position for the specified profile, based on the current position of the master axis.
- This slave axis position can be used to command the slave axis to move to the proper location prior to commanding a MC_CamIn move with StartMode = 0 (Start mode).
- The typical application of MC_CamStartPos is to aid in positioning a slave axis to its starting position for a MC_CamIn move with a slave absolute profile.
- See Positioning an Axis Before Starting Camming for instructions.
