5.3.4 Executing a homing run
During initial start-up of an actuator, also execute a homing run to determine the homing point. The
reference point is saved temporarily in the motor controller. When there is an open circuit in the logic
power supply, the homing point is lost and the homing run must be repeated.
The required settings for the dimensional reference system and the homing run are taken from the
parameter file of the actuator (
è
Parameter list).
When required, automatic execution with FCT can be enabled (
è
Tab. 2.25)
In delivery condition, automatic running of the homing function is disabled.

Chapter 2.5.2
Requirements:
– The actuator is completely configured and parameterised by a parameter file
– With homing on a reference switch: the inputs for the reference switch are enabled.
Carrying out homing
1. Approval by web server:
Enable“Parameters”, section“Control”,“Device Control”.
Enable“Parameters”, section“Control”,“Control Enable”.
2. During initial start-up: check functionality of the actuator.
Move actuator manually with <Jog neg.> or <Jog pos.> in both directions.
Check direction of rotation/direction of travel of the electromechanical actuator.
Optional: enable reversal of direction of rotation with FCT.
Check signal characteristics of the digital I/O (e.g. reference switch).
3. Click <Start Homing> button.
Following successful completion of homing, the actuator is referenced to the dimensional reference
system.
4. During first commissioning: Check end positions
Move actuator in both directions with <Jog neg.> or <Jog pos.>.
Check displayed positions of the axis.
Move to the limits of the positioning range and check the software end positions.
