Function:
Function:
NOTICE
[-32000 -
This parameter is only
available with software version
48.XX.
Enter the speed for the homing
functions (parameter 17-80 Homing
Function, options [10]–[13]).
Function:
NOTICE
[0 - 500 %]
This parameter is only
available with software version
48.XX.
Enter the torque limit for the
homing functions
(parameter 17-80 Homing Function,
options [10]–[13]).
Function:
NOTICE
[0.1 - 6000.0
This parameter is only
available with software version
48.XX.
Enter the timeout for the homing
functions (parameter 17-80 Homing
Function, options [10]–[13]). If the
frequency converter does not
detect the homing sensor or does
not reach the torque limit within
the timeout time, it aborts the
homing process and trips.

17-87 Homing Activation
Option:
Function:
Select when the Homing Ok signal
is cleared.
Clear at Homing Ok is cleared at power up
Powerup and a new homing is needed for
subsequent positioning operations.
The option is a typical selection
when using incremental encoder
and the position tracking is lost at
power down only.
Clear at Coast Homing Ok is cleared at every
motor coast and a new homing is
needed. The option is a typical
selection for sensor less control as
position tracking is lost when
motor is coasted.
Clear at Coast Homing Ok is cleared at motor
Running coast only while motor is running
and a new homing is needed. The
option is a typical selection for
sensor less control with a
mechanical brake holding the
position at stand still.
Clear at Homing Ok is only cleared at new
Homing Only start of the selected homing
function. The option is a typical
selection for absolute encoders.
After completing the selected
homing function
parameter 17-74 Position Offset is
automatically set to the offset
calculated by: Parameter 17-74 =
(Parameter 17-82.0) - (Position value
read from encoder).
Start a new homing to re-calculate
Parameter 17-74, for example, after
replacing the encoder.
Function:

Activation manner of drive homing
and master homing. Master homing
can be activated by a Set Master
Home signal or the Start Homing
signal by selecting options [2]
Manual and Master and [3] Auto and
Master.
