Identifier Type Description: System variable/value range/index Part pro Sync O S
$SC_PA_ACTIV_I
MMED
BOOL $SC_PA_ACTIV_IMMED[n]
Protection zone active immediately?
TRUE: The protection zone is active immediately upon start-up of the
control and referencing of the axes
FALSE: The protection zone is not active immediately
n: Number of protection zone 0 – (maximum value settable via MD)
RW 2

RW 2
$SC_PA_ORI
INT $SC_PA_ORI[n]
Orientation of protection zone
0: Polygon in plane from 1st and 2nd geo axis
1: Polygon in plane from 3rd and 1st geo axis
2: Polygon in plane from 2nd and 3rd geo axis
n: Number of protection zone 0 – (maximum value settable via MD)
RW 2
$SC_PA_LIM_3DI
M
INT $SC_PA_LIM_3DIM[n]
