The feedrate override entered at the PLC interface is ignored.
When the feedrate override is inactive, the NC always uses 100% as the
internal override factor.
Note:
The 1st switch position of the gray-coded interface for the value is an
exception. Also here, for "Feedrate override inactive", this override factor is
used and for axes, 0% is output as override value (acts the same as
"feedrate disable").

The feedrate override is inactive when G33 is active.
