4.6 Fixture Configuration
Fixture refers to the location at which products are physically constrained in the workcell. It consists of
both position (XYZ) coordinates and a corner constraint (Front Left, Front Right, Back Left, or Back
Right). On conveyorized systems, the fixture is typically the combination of a clamp and a stop. On non-
conveyorized systems, it is usually a manual fixture.
4.6.1 Fixture Constraint Location
ECNT uses the fixture constraint coordinates and the length and width of the board or carrier to determine
the Main Pattern Edit Frame coordinates. The Fixture Constraint Location is the corner of the product that
is always in the same location when the product is in the fixture (the repeatable corner). ECNT calculates
the position of the front-left corner of the product from the repeatable corner, using the product's length
and width. See Figure 4-6.
Conveyorized systems will always use a front corner as the constraint location, because the fixed rail is
located at the front of the workcell. For example, if the conveyor movement is from left to right, and the
fixed rail is the front rail, then the constraint location is
Front Right. If the conveyor movement is right to
left, then the constraint location is
Front Left.

" NOTE Do not use the stop location as the constraint location. If the front rail is fixed and the
product flow is left-to-right, the constraint is Front Right, even if the stop is mounted on
the rear rail.
