17-80 Homing Function
Option:
Function:
[0]
*
No
Homing
No homing function. The actual position is 0
after power-up, independent of the physical
machine position.
[1]
Home
Position
Actual position is set to the value of
, 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.
[9]
Direction
with
Sensor
Perform a search for the homing sensor in the
direction defined by the forward/reverse signal
on a digital input or fieldbus, using the settings
in
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
, index 0.
The frequency converter then switches to the
positioning mode with a target defined in
, index 0 + index
1. If reversing is required for going to the target
position, set
to
[2] Both directions
.
[10] Forward
with
sensor
Perform a search for the homing sensor in
forward direction using the settings in
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
, index 0.
The frequency converter then switches to the
positioning mode with a target defined in
, 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
with
sensor
Same as
[10] Forward with sensor
, but with the
search in the reverse direction. Set
parameter 4-10 Motor Speed Direction
to
[1]
Counter clockwise
or
[2] Both directions
.
[12] Forward
Torque
Limit
With this option selected, the frequency
converter does the following:
17-80 Homing Function
Option:
Function:
1.
Runs forward with the set homing
speed (
).
2.
When the torque reaches the limit set
in
, and the speed is lower than the
value in
, the actual position is set to
the value of
, index 0.
3.
The frequency converter positions to
the target defined in
, index 0
+ index 1.
Only available in flux closed loop.

[13] Reverse
Torque
Limit
Same as
[12] Forward Torque Limit
but in reverse
direction. Set
to
[1] Counter clockwise
or
[2] Both
directions
. Only available in flux closed loop.
[14] Direction
with Z
Pulse
Same as
[9] Direction with Sensor
but with
encoder zero pulse as home sensor.
[15] Forward
with Z
Pulse
Same as
[10] Forward with Sensor
but with
encoder zero pulse as home sensor.
[16] Reverse
with Z
Pulse
Same as
[11] Forward with Sensor
but with
encoder zero pulse as home sensor.
[17] Direction
with S &
Z
Same as
[9] Forward with Sensor
but moving to
encoder zero pulse after finding the home
sensor.
[18] Forward
with S &
Z
Same as
[10] Forward with Sensor
but moving to
encoder zero pulse after finding the home
sensor.
[19] Reverse
with S &
Z
Same as
[11] Reverse with Sensor
but moving to
encoder zero pulse after finding the home
sensor.
