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 9/440HR 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.
