Technical Features
All types of this product line are Z positioners with crossed roller bearings including an anti-
creep system.
Position Sensors
Models L-306.011112 and L-306.013112 include a linear incremental encoder. For
specifications, see the “Technical Data” section (p. 19).
Limit Switches
The product provides optical limit switches.
Each limit switch closes a contact on a dedicated line to the controller. If reached, the controller
stops the motion. If the controller does not stop the motion in time, the positioner runs into a
hard stop.
Reference Point Switch
The positioner is equipped with one direction-sensing reference point switch that is located at
about the midpoint of the travel range. This sensor provides a TTL signal indicating whether the
positioner is on the positive or negative side of the reference point switch.
The commands that use the reference signal are described in the user manual for the controller
and/or in the corresponding software manuals.

Mechanical Installation
General Notes on Installation
NOTICE
Electrostatic hazard
Touching the pins in the connections of the positioner can damage electrostatic sensitive
devices (ESD) of the positioner. Also for this reason, the positioner is supplied with a
protection cap on the connector.
Do not remove the protection cap from the connector until you connect the positioner
to the controller.
NOTICE
Cable break!
A cable break leads to failure of the positioner.
Install the positioner so that the cable is not bent too strongly or crushed.
NOTICE
Heating of the positioner during operation!
The heat produced during operation of the positioner can affect your application.
Install the positioners that the application is not impaired by the dissipated heat.
Avoid excess of the allowed max. velocity (5 mm/s). Operation within the allowed
velocity range is automatically ensured by correct selection/detection of the product
model in the motion control software.
INFORMATION
For optimal repeatability, all components must be connected firmly together.
INFORMATION
The use of locating pins during mounting reduces deviations from the ideal alignment of the
positioner.
If possible, simulate the positioner motion with a mounted load or make suitable
calculations to detect collisions or unfavorable center of gravity constellations.
If necessary, take suitable constructive measures to avoid collisions and instability in
the overall system.

Maintenance
General Notes on Maintenance
NOTICE
Damage due to improper maintenance!
Improper maintenance can result in misalignment and failure of the L-306.
Only loosen screws according to the instructions in this manual.
Performing a Maintenance Run
Depending on the operating conditions and the period of use of the L-306, the following
maintenance measures are required:
Maintenance run
The maintenance run serves to distribute the existing lubricant.
After 500 operating hours or at least after 1 year, perform a maintenance run over the
entire travel range, in order for the existing lubricant to be distributed evenly.
If you operate your positioner continuously over only a short travel range (<20%of the
entire travel range), perform a run across the entire travel range approximately every
2000 motion cycles.
Lubrication
Under laboratory conditions, the positioner needs extra lubrication in exceptional cases only.
For continuous industrial use, the lubrication intervals must be defined individually.
Do not relubricate the L-306 without consulting our customer service department.
(p. 17).
