8.6 Homing
The measuring system in the machine is selected by means of homing and the 0 position is set
within the possible physical travel range:
[8-25] Homing (selection of 0 position)
The zero position (home) can be defined by a reference run or by setting a home position:
• If a reference run is carried out, the drive follows a previously selected path to find the home
position.
• When the reference is set, it is selected manually when the drive stands still.
 Tip!
A reference run is mainly used for systems with feedback via encoders, resolvers, or single-
turn absolute value encoders, as in the case of these systems the home position is lost
when the supply voltage is switched off.
Usually the reference is set only once during commissioning or in the event of service (e. g.
if drive components are replaced), and it is mostly used for systems with feedback via
absolute value encoders.

 Danger!
During homing operations, specially assigned profile parameters are effective. If these
parameters are not set correctly, the drive may execute unexpected movements!
 Note!
Currently, the 8400 HighLine inverter only supports the evaluation of incremental
signals (encoder). The home position is always deleted after mains switching.
