2.1.5 Module description
The following types of the module SA-1are available:
Type Nominal stroke

SA-1-100
SA-1-150 100 mm
100 mm
Motor attachment optionally on the front left or right side or on the rear axial side.
The modules of the SA-series are modules with a movable bracket.
Compared with the usual slide model this type
series offers the advantage to “dip”
into the working area and to leave it again completely. The bracket (2) is moved
along a linear guide (3) vis-à-vis the base body (1). A ball-type linear drive (4) with a
spindle nut mounted on the bracket (2) transforms the rotary movement in a linear
movement.
The spindle is driven by a servomotor (7) via a toothed belt back gear (5) or a torsion
ally stiff coupling (6).
The reference switch (10) is an inductive sensor which recognizes the home position
of the bracket during the reference run.
The servomotor (7) can also be equipped with an integrated parking brake (8) which
secures the bracket position when the module is not energized.

This parking brake is required by all means in case of vertical applications!
