Torque limitation value
Indicates the value programmed by means of
FXST[x] or
SD43510 $SA_FIXED_STOP_TORQUE

The machine axis is not cross-referenced using position measurement
system 1 or 2.
The machine axis has reached the reference point (incremental
measuring system) and/or target point (length measuring system with
distance coded reference marks) during reference point approach.
No obligation to cross-reference (NC start possible without cross-
referencing this axis)
There is no obligation to cross-reference for the NC start.
