Name
Description
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 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 tor-
que limit
With this option selected, the drive does the following:
Runs forward with the set homing speed (parameter 17-83 Homing Speed).
When the torque reaches the limit set in parameter 17-84 Homing Torque Limit, and the speed is low-
er 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.
The drive positions to the target defined in parameter 17-82 Home Position, index 0 + index 1.
Only available in flux closed loop. See also parameter 17-85 Homing Timeout.
[13]
Reverse tor-
que limit
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.
[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] Reverse with Sensor but with encoder zero pulse as home sensor.
[17]
Direction
with S & Z
Same as [9] Direction 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.
[20]
Fwd. II with
sensor
When on the correct side of the home sensor, performs a search for home sensor in forward direction
using the settings in parameter 17-83 Homing Speed, and then reverses with 10% of Homing Speed when
home sensor is detected. The falling edge of home sensor signal is set to the value defined in parameter
17-82 Home Position, index 0. When on the wrong side of the home sensor, the positive end limit switch
is reached without detecting the home sensor, the drive reverses until home sensor is passed. After the
home sensor is detected, the search for home sensor is performed in forward direction, as described.
[21]
Rev. II with
sensor
When on the correct side of the home sensor, performs a search for home sensor in the reverse direction
using the settings in parameter 17-83 Homing Speed, and then moves forward with 10% of Homing
Speed when home sensor is detected. The falling edge of home sensor signal is set to the value defined
in parameter 17-82 Home Position, index 0. When on the wrong side of the home sensor, a negative end
limit switch is reached without detecting the home sensor, the drive 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.
