ATTENTION: The E–Stop status relay (or your
customer–supplied E–Stop control relay) should not be the
only method through which axis brakes are directly
released (see the illustration below). Brakes should be
released by a combination of the PAL logic when it
determines that the 9/440 system is in full control of the
servo motors and the control’s E–Stop status contact and an
external hardware E–Stop contact. Refer to the description
of the PAL flags $AXME and $STME for details about
testing drive status.
