Wait for Completion:
If enabled, the program counter does not advance to the next
block until the shift is complete.
Required Conditions
None
Additional Information
NOTE: Prior to MW+ release 2.56 and system Ladder 223, this block’s Offset property
was an absolute shift. To improve accuracy, 2.56 MW+ with System Ladder 223
performs relative shifts, while keeping the absolute shift value internally in terms of
counts.
NOTE: System ladder 228 or greater allows shifting over time or relative change of the
master.
NOTE: If the block is configured for position based shift, if the master stops and moves
backwards the shift will “shrink.” If the master moves beyond the original location
where the CAM SHIFT block first executed, the shift will “advance” again because the
absolute value of the relative position is used to determine the required shift amount.
(Care should be taken that the master does not move backwards, the resulting shift
will be incorrect.)
NOTE: If the STOP block is used while the CAM SHIFT is in progress, the CAM
SHIFT will be aborted at it uncompleted location.
