2.22 Dynamic Feeds Interface
The Dynamic Feeds interface is somewhat
different from most of the feed interfaces. Many of
the feed functions are controlled from a small
keypad and screen that connects to the only
available communications port on the feed control
itself. A special adapter board must be used to
communicate with the feed. This feed is only
supported on the new communications board.
The connection to a Dynamic Feeds Servo Feed
is as follows:

Notes:
‚ Link makes a small adapter board ( PN 107858)
that plugs into the Pacific Scientific SC750
servo controller communications port (J58) to
provide 2 communications connectors. The
Dynamic Feeds operator interface (if present)
plugs into one connector (either one), and the
Link feed interface cable plugs into the other.
‚ Port 4 of the new communications board must
be jumpered for RS-485 operation. See section
3.3 for configuration information.
‚ If the feed is powered down but the System
5000 is not, the feed will lose the current length
and speed values but the 5000 will not know
that. To reset the values in the feed, the feed
screen on the OmniLink OIT must be entered
and the length reprogrammed. This will reset
both values. If both units are powered down,
everything will be reset automatically.
‚ This feed will not communicate when it is
“Armed” and waiting for a feed initiate signal.
When recalling a job with the feed armed, the
feed screen on the OmniLink OIT will report a
communications failure to the feed. Hit the
“Program/Interrupt” button to disarm the feed
and the new feed parameters will be sent to the
feed. The new feed length should be displayed
on the feed OIT at that point.
