Parameter Descriptions
17-80 Homing Function
Option: Function:
[4] Analog Same as [3] Analog Input 53, but for analog
Input 54 input 54.
[9] Direction Perform a search for the homing sensor in the
with direction defined by the forward/reverse signal
Sensor on a digital input or fieldbus, using the settings
in parameter 17-83 Homing Speed and
parameter 17-84 Homing Torque Limit. When the
frequency converter 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
frequency converter then switches to the
positioning mode with a target defined in
parameter 17-82 Home Position, index 0 + index
1. If reversing is required for going to the target
position, set parameter 4-10 Motor Speed
Direction to [2] Both directions.
[10] Forward Perform a search for the homing sensor in
with forward direction using the settings in
sensor parameter 17-83 Homing Speed and
parameter 17-84 Homing Torque Limit. When the
frequency converter 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
frequency converter then switches to the
positioning mode with a target defined in
parameter 17-82 Home Position, index 0 + index
1. If reversing is required for going to the target
position, set parameter 4-10 Motor Speed
Direction to [2] Both directions.
[11] Reverse Same as [10] Forward with sensor, but with the
with search in the reverse direction. Set
sensor parameter 4-10 Motor Speed Direction to [1]
Counter clockwise or [2] Both directions.
[12] Forward With this option selected, the frequency
Torque converter does the following:
Limit 1. Runs forward with the set homing
speed (parameter 17-83 Homing Speed).
2. When the torque reaches the limit set
in parameter 17-84 Homing Torque
Limit, and the speed is lower than the
value in parameter 3-05 On Reference
Window, the actual position is set to
the value of parameter 17-82 Home
Position, index 0.
3. The frequency converter positions to
the target defined in
parameter 17-82 Home Position, index 0
+ index 1.
Only available in flux closed loop.

Function:
Same as [12] Forward Torque Limit but in reverse
direction. Set parameter 4-10 Motor Speed
Direction to [1] Counter clockwise or [2] Both
directions. Only available in flux closed loop.
Function:
NOTICE
This parameter is only available with
software version 48.XX.
Select the trigger for the homing synchroni-
zation 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
Position:
•
Index 0 if the homing sensor is
approached in the forward direction.
•
Index 1 if the homing sensor is
approached in the reverse direction.
After power-up, the first detection of the
homing sensor triggers the function.
After power-up, the first detection of the
homing sensor in the forward direction
triggers the function.
After power-up, the first detection of the
homing sensor in the reverse direction triggers
the function.
After start, the first detection of the homing
sensor triggers the function.
After start, the first detection of the homing
sensor in the forward direction triggers the
function.
After start, the first detection of the homing
sensor in the reverse direction triggers the
function.
Every detection of the homing sensor triggers
the function.
Every detection of the homing sensor in the
forward direction triggers the function.
Every detection of the homing sensor in the
reverse direction triggers the function.
