[0]* Clear at Homing Ok is cleared at power-up and a new homing is needed for subsequent positioning operations.
power-up The option is a typical selection when using incremental encoder and the position tracking is lost at pow-
er-down only.
[1] Clear at
Homing Ok is cleared at every motor coast and a new homing is needed. The option is a typical selection
coast for sensorless control as position tracking is lost when motor is coasted.
[2] Clear at Homing Ok is cleared at motor coast only while motor is running and a new homing is needed. The option
coast run-
is a typical selection for sensorless control with a mechanical brake holding the position at stand still.
ning
[3] Clear at
Homing Ok is only cleared at new start of the selected homing function. The option is a typical selection
homing on-
for absolute encoders. After completing the selected homing function parameter 17-74 Position Offset is
ly
automatically set to the offset calculated by: Parameter 17-74 Position Offset = (Parameter 17-82.0 Home
Position) - (Position value read from encoder). Start a new homing to re-calculate Parameter 17-74 Position
Offset, for example, after replacing the encoder.

[0]* Manual
Activates homing function selected in parameter 17-80 Homing Function using the Start Homing signal.
[1] Auto
Homing function selected in parameter 17-80 Homing Function is activated automatically when the
Homing OK signal is low and start signal is applied.
[2] Manual and
Activates homing function selected in parameter 17-80 Homing Function and sets the actual master po-
master
sition as defined in parameter 17-88 Master Home Position, using Start Homing signal.
[3] Auto and
Homing function selected in parameter 17-80 Homing Function is activated automatically when the
master
Homing OK signal is low and start signal is applied. The actual master position is set as defined in pa-
rameter 17-88 Master Home Position.
