Protection zones
4.3 Checking for protection zone violation, working area limitation and software limits
Job planning
4-8 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
Parameters
Status 0: Function OK;
the defined path can be traversed completely.
–: In _DLIMIT at least one component is negative
–: An error occurred in a transformation calculation.
If the defined path cannot be traversed completely, a positive,
decimally coded value is returned:
Units digit (type of violated limit):
1: Software limits are limiting the traverse path.
2: Working area limitation is limiting the traverse path.
3: Protection zones are limiting limit the traverse path.
If several limits are violated at once (e.g. software limits and
protection zones), the limit leading to the greatest limitation of
the traverse path is indicated in a units digit.
Tens digit
10:
The start value is violating the limit.
20:
The defined straight line is violating the limit. This value is
also returned if the end point does not violate any limit itself
but a limit value would be violated on the path from the start to
the end point (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 limitation).
100:
Only 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 limitation).
200:
Only 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 is multiplied that violates
the limit (only if the units digit is 1 or 2, i.e. for software
limits and working area limitation).
The axis count starts at 1 and refers in the case of violated
software limits (units digit = 1) to the machine axes and in the
case of a working area limitation (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 leading to the
greatest limitation of the traverse path is indicated in the
hundreds and thousands digit of the protection zone.
