Position In Specified Reference Range (Posrange) - Siemens SINUMERIK 840D sl Programming Manual

10.4.13

Position in specified reference range (POSRANGE)

Function
The POSRANGE( ) function can be used to determine whether the current interpolated
setpoint position of an axis is in a window around a specified reference position. The position
specifications can refer to coordinates systems which can be specified.
The module offset is taken into account when interrogating the actual axis position of a
module axis.
Note
The function can only be called up from the synchronized action. If called up from the parts
program, the alarm 14091 %1 block %2 is triggered, function not permitted, index: %3 with
index 5 called up.

MCS is active (option). The following are possible:
0 for MCS (machine coordinates system)
1 for BCS (basic coordinates system)
2 for SZS (settable zero system)
3 for WCS (workpiece coordinate system)
