ATTENTION: Brake control should not be directly released by
the E--Stop status relay (or your customer supplied E--Stop
control relay). Brakes should only be released by the PAL logic
when it has determined that the 9/440 resolver--based control is
in full control of the servo motors and the control is out of
E--Stop. See the description of the PAL flag $PFLT.15 for detail
on how to test drive status.
