4 2 Closing modes
4 2 1 Force priority
With this closure function, closure takes place at a defined closure force,
which is controlled by the Control Unit.
The deformation of the clamp and the parts being clamped results in a
closing gap. The closing gap can be used to verify the position of the
assembled components; however, this gap is subject to change due to
various tolerances (of the parts being clamped, the clamp itself, and the
nozzle).
force priority closure is used to close the ear clamps. The performance of
the clamp depends on the closing force (and not on the closing gap).
The figure to the right shows a simplified force priority
closing process.
4 2 2 Stroke priority
With this closure function, closure takes place at a defined closure gap,
which is regulated by the Control Unit.
The resistance of the parts being clamped and the resistance of the
clamp itself result in a closing force. This closing force is needed in order
to move to the given position. The closing force can be used to verify the
assembled components; however, this force is subject to change due to
various tolerances (of the parts being clamped, the clamp itself, and the
nozzle).
The stroke priority closure function is used to close low-profile clamps.
because the performance of a low-profile clamp is guaranteed only when
the hook is engaged, the ePC 01 closes up to a certain gap value at
which the engagement of the low-profile clamp is ensured.
The figure to the right shows a simplified stroke-priority closing process.
