4.4.1 Base Body
The base body is the basis of the positioner. The L-412.xx9232B is mounted onto a surface
via the base body (p. 15).
The base body comprises the following subassembly (subassemblies):
Drive screw
The drive screw converts the rotary motion of the drive to linear motion of the motion
platform.
Limit switches
The limit switches are sensors at each end of the travel range that enable the electronics to
abort motion in order to prevent the motion platform from colliding with the mechanical
hard stop.
4.4.2 Drive
The drive generates the torque required for the dynamics of the motion platform.
4 PRODUCT DESCRIPTION L412M0009EN ‒ 9/10/2019
10 MOTION | POSITIONING

The drive comprises the following subassembly (subassemblies):
Motor
The motor generates the torque required for the dynamics of the motion platform.
Rotary encoder
The rotary encoder measures the motor shaft's angle of rotation. This signal can be used by
suitable electronics for commutating the motor and for calculating the position of the motion
platform after a reference move .
4.4.3 Holding brake
The holding brake blocks the drivetrain at rest.
The holding brake is designed for holding only and is not suitable for continuous braking
during operation.
The holding brake blocks in a zero voltage state.
4.4.4 Purge Air System
The purge air system protects the drive and guides of the L-412.xx9232B against surrounding
dust.
The purge air system comprises the following subassembly (subassemblies):
4 PRODUCT DESCRIPTION L412M0009EN ‒ 9/10/2019
11 MOTION | POSITIONING

Passive dust protection
The passive dust protection consists of covering strips that seal the openings on the side of
the L-412.xx9232B's base body and therefore reduces the amount of dust that can penetrate.
Active dust protection
The active dust protection consists of a purge air connector on the base body of the
L-412.xx9232B, which creates a slight overpressure in the L-412.xx9232B and therefore
reduces the amount of dust that can penetrate.
