3.3 Checking for protection zone violation, working area limitation and software limits (CALCPOSI)
Job Planning
Programming Manual, 06/2009, 6FC5398-2BP20-0BA0
Tens digit
10:
The initial value violates the limit
20:
The specified straight line violates the limit. This value is also
returned if the end point does not violate any limit itself but
the path from the starting point to the end point would cause
a limit value to be violated (e.g. by passing through a
protection zone, curved software limits in the WCS for non-
linear transformations, e.g. transmit).
Hundreds digit
100:
The positive limit value is violated (only if the units digit is 1 or
2, i.e. for software limits and working area limits)
100:
An NCK protection zone is violated (only if the units digit is 3).
200:
The negative limit value is violated (only if the units digit is 1
or 2, i.e. for software limits and working area limits)
200:
A channel-specific protection zone is violated (only if the units
digit is 3).
Thousands digit
1000:
Factor, by which the number of the axis that violates the limit
is multiplied (only if the units digit is either 1 or 2, i.e. for
software limits and working area limits).
The axis count starts at 1 and refers in the case of violated
software limits (units digit = 1) to the machine axes and for
violated working area limits (units digit = 2) to the geometry
axes.
1000:
Factor by which the number of the violated protection zone is
multiplied (only if the units digit is 3).
If several protection zones are violated, the limit resulting in
the greatest limitation of the traversing path is indicated in the
hundreds and thousands digit of the protection zone.
