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.
Determining Your Type of Input
Before you ground or wire your 1394 system, you must determine the type
of 360/480V input power you will be connecting to. The 1394 system is
designed to operate in both grounded and ungrounded environments.
