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
Conversion index: -
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.
Op- Name Description
tion
[0]* No homing No homing function. The actual position is 0 after power-up, independent of the physical machine posi-
tion.
[1] Home posi- Actual position is set to the value of parameter 17-82 Home Position, index 0.
tion
[2] Home sync
Homing position is synchronized with the homing sensor according to the setting in parameter 17-81
function
Home Sync Function.
[3] Analog input
Use the value of analog input 53 as the actual position. The value is scaled according to parameter 3-06
53
Minimum Position and parameter 3-07 Maximum Position.
[4] Analog input Same as [3] Analog input 53, but for analog input 54.

[5] Home latch Only latching of the actual position every time the home sensor is detected without executing any hom-
function
ing function. The result is updated in parameter 18-25 latched Actual Pos.
[9] Direction Perform a search for the homing sensor in the direction defined by the forward/reverse signal on a digi-
with sensor 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 Perform a search for the homing sensor in forward direction using the settings in parameter 17-83 Hom-
sensor
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
