Meaning of the various parameters:
Parameter Value Description
Yes The axis must be homed in order to execute
absolute motion commands.
Homing required
No The axis must not be homed in order to
execute absolute motion commands.
Homing mode For this homing mode:
Homing mode: "BERO only"
Positive
direction
Reference point approach in positive direction.
Negative
direction
Reference point approach in negative
direction.
Direction of movement
Current
direction
Reference point approach in negative
direction.
Left side of
BERO
Direction of movement: positive
Axis homing is triggered at the positive edge.
Direction of movement: negative
Axis homing is triggered at the negative edge.
BERO signal edge
Right side of
the BERO
Direction of movement: positive
Axis homing is triggered at the negative edge.
Direction of movement: negative
Axis homing is triggered at the positive edge.
Disabled Distance up to BERO detection not monitored Max. distance to BERO
Enabled Monitoring of the distance between the start of
the reference point approach and BERO
detection. If the difference in this distance
exceeds the configured distance, the
corresponding technology DB indicates error
801D. The homing function is canceled.
Note
To home the axis to BERO, interconnect the BERO as digital input with the measured value
input of the drive component.
Note
In order to execute the homing function in "BERO only" mode, select "Direction of
movement" and "BERO edge" values which correspond with the configuration or drive
functionality for detecting the BERO edge. The "BERO edge" and "Direction of movement"
parameters do not configure the measuring function in the drive, but rather reflect its
functionality.
For information on the configuration of BERO detection, refer to the relevant product
information or to the drive manuals.
