Parameter Value Description
Positive
direction
Reference point approach in positive direction.
Start reference point
approach
Negative
direction
Reference point approach in negative
direction.
Approach velocity Velocity at which the axis approaches the
BERO.
Entry velocity Velocity at which the axis approaches the
(shifted) homing position after detection of the
zero mark.
Shutdown velocity Velocity at which the axis approaches the
homing position coordinate after detection of
the BERO.
Homing position offset A homing position offset shifts the homing
position by the configured distance. The axis
moves by a configured distance after its
synchronization at the BERO edge at the
velocity defined under Homing Velocity.
Modulo axes always take the shortest
distance.
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 reference point approach 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 reference point approach in "BERO only" homing mode, select
"Signal transition" and "BERO edge" values which correspond with the drive
configuration or functionality. The "Signal transition" and "BERO edge" parameters
do not configure the measuring function in the drive, but rather reflect their
functionality in order to control axis motion according to the configuration.
For information on the configuration of BERO detection, refer to the relevant
product information or to the drive manuals.
