5.17.8 17-8* Position Homing
Parameters for configuring the homing function. The homing function creates a position reference in the physical machine.
Parameter 17-80 Homing Function
Table 950: Parameter 17-80 Homing Function
17-80 Homing Function
Default value: [0] No homing
Parameter type: Option
Setup: All setups
Conversion index: -
Data type: Uint8
Change during operation: False
N O T I C E
This parameter is only available with software version 48.XX.
Select the homing function. The homing function creates a position reference in the physical machine. The selected homing func-
tion can be activated with a digital input or a fieldbus bit. Homing is not required when using absolute encoders. All homing func-
tions except
[2] Home Sync Function
require a start homing signal.

Name
Description
[0]*
No homing
No homing function. The actual position is 0 after power-up, independent of the physical machine posi-
tion.
[1]
Home posi-
tion
Actual position is set to the value of
parameter 17-82 Home Position
, index 0.
[2]
Home sync
function
Homing position is synchronized with the homing sensor according to the setting in
parameter 17-81
Home Sync Function
.
[3]
Analog input
53
Use the value of analog input 53 as the actual position. The value is scaled according to
parameter 3-06
Minimum Position
and
parameter 3-07 Maximum Position
.
[4]
Analog input
54
Same as
[3] Analog input 53
, but for analog input 54.
[5]
Home latch
function
Only latching of the actual position every time the home sensor is detected without executing any hom-
ing function. The result is updated in
parameter 18-25 latched Actual Pos
.
[9]
Direction
with sensor
Perform a search for the homing sensor in the direction defined by the forward/reverse signal on a digi-
tal input or fieldbus, using the settings in
parameter 17-83 Homing Speed
and
parameter 17-84 Homing
Torque Limit
. When the drive detects the homing sensor input (configured in
parameter group 5-1* Digital
Inputs
), it sets the actual position to the value of
parameter 17-82 Home Position
, index 0. The drive then
switches to the positioning mode with a target defined in
parameter 17-82 Home Position
, index 0 + in-
dex 1. If reversing is required for going to the target position, set
parameter 4-10 Motor Speed Direction
to
[2] Both directions
.
[10]
Forward with
sensor
Perform a search for the homing sensor in forward direction using the settings in
parameter 17-83 Hom-
ing Speed
and
parameter 17-84 Homing Torque Limit
. When the drive detects the homing sensor input
(configured in
parameter group 5-1* Digital Inputs
), it sets the actual position to the value of
parameter
17-82 Home Position
, index 0. The drive then switches to the positioning mode with a target defined in
