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.
- See Function Blocks - General Rules about how inputs and outputs work.
- If this function block is called and the active move is not a MC_CamIn move, this function block returns an error and the active move is not aborted.
- This function block:
- Aborts the active MC_CamIn move.
- Disengages the axis from its master.
- Disengages the slave axis from a MC_CamIn move.
- Commands the axis to continue at its current velocity.
- The axis continues to run at this velocity until this MC_CamOut move is aborted.
-
-
The current velocity is calculated by taking the average of the actual velocity during the previous 16 cycles.
Cancel the Cam Motion
- An alternative method to cancel the cam motion is a single axis move (MC_MoveAbsolute, MC_MoveRelative, MC_MoveAdditive, MC_MoveVelocity, and MC_Halt) with the BufferMode input set to 0 (zero).
- This cancels the MC_CamIn function and starts the new motion function on the slave axis.
- Many applications prefer calling MC_Halt instead of MC_CamOut because it does not send a velocity command to the slave axis.
