4.3.1 Base Body
The base body is the basis of the positioner. The L-412.xx9211E1 is mounted onto a surface
via the base body (p. 18).
The base body comprises the following subassembly (subassemblies):
Reference switch
The reference switch (p. 33) is a sensor whose fixed position serves as the reference point
for incremental sensor signals.
Limit switches
The limit switches (p. 34) 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.
Incremental linear encoder
The L-412.xx9211E1's linear encoder is an incremental sensor: It measures the position of the
motion platform relative to a known reference point. Linear encoders measure the actual
position directly. Therefore, drive errors such as nonlinearity, backlash or elastic deformation
cannot influence position measuring.
4.3.2 Drive
The drive generates the force that is required for the dynamics of the L-412.xx9211E1.

12 MOTION | POSITIONING

Figure 5: Drive with holding brake of the L-412
The drive comprises the following subassembly or subassemblies:
Motor
The motor generates the force required to move the fixed load.
The motor of the L-412.xx9211E1 has a commutation encoder. For information on coding,
refer to "Commutation Encoder" (p. 36).
In the case of the L-412.xx9211E1, overheating is prevented using temperature
sensors (p. 34).
Drive screw
The drive screw converts the rotary motion of the drive to linear motion 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 .
4.3.3 Holding Brake
For L-412.xx9211E1B models:
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.
4.3.4 Drag Chain
The drag chain (also: energy chain or energy supply chain) guides and protects the
L-412.xx9211E1's flexible cables and lines.
4.3.5 Purge Air System
The purge air system protects the drive and guides of the L-412.xx9211E1 against
surrounding dust.
The purge air system comprises the following subassembly (subassemblies):
4 PRODUCT DESCRIPTION L412UM0003EN ‒ 10/24/2022
13 MOTION | POSITIONING

Passive dust protection
The passive dust protection consists of covering strips that seal the openings on the side of
the L-412.xx9211E1'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.xx9211E1, which creates a slight overpressure in the L-412.xx9211E1 and therefore
reduces the amount of dust that can penetrate.

same or similar thermal expansion properties as the L-412.xx9211E1.
✓You have accounted for the space required to route cables according to regulations and
without bending them.
■The cable routing does not obstruct the motion of the L-412.xx9211E1.
■The cable does not rub against sharp edges during movements of the L-412.xx9211E1.
Mounting the L-412.xx9211E1 from above
1. Optional: Insert the locating pins into the corresponding holes in the underlying surface.
2. Align the L-412.xx9211E1 on the underlying surface so that the corresponding mounting
holes in the L-412.xx9211E1 and underlying surface are in line.
3. Put the L-412.xx9211E1 onto the underlying surface so that the locating pins can be
inserted into the corresponding locating holes of the L-412.xx9211E1.
4. If necessary: Allow access to the mounting holes in the base body of the L-412.xx9211E1.
Possible measures:
■Starting and operating the positioner (p. 24) temporarily, and commanding the
motion platform to a suitable position
■Moving the platform by hand (p. 27)
5. Tighten all screws in the mounting holes.
Recommended torque: 3 Nm
6. If necessary: Repeat steps 4 and 5 for all concealed mounting holes.
7. Check that the L-412.xx9211E1 is sitting firmly on the underlying surface.
6.2 Connecting the L-412.xx9211E1 to the Protective Earth Conductor
The L-412.xx9211E1 must be connected to the protective earth conductor via the drive
connector: For this purpose, the protective earth connector on the motor plug on the drive
electronics side must be connected to an earth connection.
If the load needs to be connected to the protective earth conductor, the L-412.xx9211E1's
base body must also be connected to the protective earth conductor. In this case, connect
the load and base body to the protective earth conductor separately.
The following description offers an example of how to connect the protective earth
conductor to the base body of the L-412.xx9211E1.
