2.2.4.
Setting the end limits
The steps described below can be best executed with energized drive.
Therefore, they may only be performed by trained and authorized personnel.
Do only travel at very low speed (<10 mm/s) and reduce the drive torque to a
minimum.
Ensure that there are no persons in the hazardous area.
The setting of the end limits depends on the application.
No sensor is to be mounted in the area of the central lubrication port
(option).
The following activation positions at the mechanical end limits result from the
initiators recommended in the catalog.

Caution!
Please add the
respective safety travels to the values mentioned above”
Stroke, usable stroke and safety travel: see in the catalog section (following the
mounting instructions) on page 14.
Sensors and limit switches: see from page 28 in the catalog section (following the
mounting instructions).
Adjusting the machine zero proximity switch
The correct position for the home switch (machine zero switch) depends on the
application
It is recommended to set the machine zero at or near the end of the travel - this
saves time, as it minimizes the chance that the machine zero is searched for in the
wrong direction. In some cases it is possible to use one of the limit switches as
machine zero, this method provides however a reduced precision, as the resulting
position can normally not be and-linked with the encoder index pulse.
