5 REPEAT
COUNT
R/W Required number of pattern repeats. If -1 the pattern
repeats endlessly. The number should be positive. When the
ABSOLUTE value of CB(4) reaches CB(5) the CAMBOX fin-
ishes if CB(6)=-1. The value can be set to 0 to terminate the
CAMBOX at the end of the current pattern.
The axis the CAMBOX is linked to can run in a positive or neg-
ative direction. In the case of a negative direction link the pat-
tern will execute in reverse. In the case where a certain
number of pattern repeats is specified with a negative direction
link, the first control block will produce one repeat less than
expected. This is because the CAMBOX loads a zero link posi-
tion which immediately goes negative on the next servo cycle
triggering a REPEAT COUNT. This effect only occurs when the
CAMBOX is loaded, not on transitions from CONTROL
BLOCK to CONTROL BLOCK. This effect can easily be com-
pensated for either by increasing the required number of
repeats, or setting the initial value of REPEAT POSITION to 1.

CONTROL
BLOCK
R/W If set to -1 the pattern will finish when the required number of
repeats are done. Alternatively a new control block pointer can
be used to point to a further control block.
