Parameter Descriptions
17-80 Homing Function
Option: Function:
When on the wrong side of the
home sensor, a negative end limit
switch is reached without detecting
the home sensor, the frequency
converter operates in forward
direction until home sensor is
passed.
After the home sensor is detected,
the search for home sensor is
performed in reverse, as described.
17-81 Home Sync Function
Option: Function:
NOTICE
This parameter is only
available with software version
48.XX.
Select the trigger for the homing
synchronization function. Only
active when [2] Home Sync Function
is selected in
parameter 17-80 Homing Function.
The homing synchronization
function sets the actual position to
the value of parameter 17-82 Home

17-81 Home Sync Function
Option: Function:
[6] Every time Every detection of the homing
sensor triggers the function.
[7] Every time Every detection of the homing
forward sensor in the forward direction
triggers the function.
[8] Every time Every detection of the homing
reverse sensor in the reverse direction
triggers the function.

Array [2]
Set the homing position in position
units defined in parameter group
17-7* Position Scaling. This is an
array parameter with 2 elements.
Indices in this parameter have a
different meaning in the following
situations:
•
If parameter 17-80 Homing
Function is set to options
[10]–[13], index 0 of this
parameter defines the
actual home position and
index 1 is used as the
homing offset, which
defines where to stop.
•
If parameter 17-80 Homing
Function is set to [2] Home
Sync Function, and
parameter 17-81 Home
Sync Function is set to [0]
1st time after power, [3] 1st
time after start, or [6] Every
time, then indices have
the following meaning:
- Index 0 is the
homing position
when the
homing sensor is
approached in
the forward
direction.
- Index 1 is the
homing position
