A3: Axis Monitoring, Protection Zones
3.3 Protection zones
Inch/metric switchovers with G70/G71 or G700/G710 are effective.
End of definition
The end of definition is defined by the following subroutine:
EXECUTE(NOT_USED)
Parameters
NOT_USED
The definition of a machine-specific or channel-specific protection zone is completed with the
subroutine EXECUTE(n).
3.3.4
Definition as per system variable
General
When the protection zones are defined via part program instructions (see Section "Definition
via part program instruction (Page 135)"), the protection zone data is stored in system
variables. The system variables can also be written directly so that the definition of protection
areas can also be performed directly in the system variables.
The same supplementary conditions apply for the definition of the contour of a protection zone
as for a protection zone definition via part program instructions.
System variables
The protection zone definitions cover following system variables:
System variable
$SN_PA_ACTIV_IMMED[n]
$SC_PA_ACTIV_IMMED[n]
$SN_PA_T_W[n]
$SC_PA_T_W[n]
$SN_PA_ORI[n]
$SC_PA_ORI[n]
