X-Y Scanner Position (feedback input) Connector
FB4 can optionally monitor the X-Y scanner's position signals and
provide additional safety-related functions. These functions are
selectable and adjustable in the FB4 menus. When implemented, the
scanner's position signals may be fed into the FB4 as described below.
If this signal is not implemented, the connector should be left
unplugged.
