Description
Performs homing with reference to the
front end of the proximity dog.
Deceleration starts from the front end of
the proximity dog. The position is shifted
by the travel distance after the proximity
dog and the home position shift distance.
The position after the shifts is set as the
home position.
Performs homing using the first Z-phase
pulse with reference to the front end of the
proximity dog.
The position specified by either the first Z-
phase signal after the front end of the
proximity dog is detected or the position of
the first Z-phase signal shifted by the
home position shift distance can be set as
the home position.
Performs homing using the last Z-phase
pulse with reference to the front end of the
proximity dog.
After the front end of the proximity dog is
detected, the position is shifted away from
the proximity dog in the reverse direction.
Then, the position specified by the first Z-
phase signal or the position of the first Z-
phase signal shifted by the home position
shift distance is used as the home
position.
Performs homing with reference to the
front end of the proximity dog in the
direction of the front end.
Starting from the front end of the proximity
dog, the position is shifted by the travel
distance after the proximity dog and the
home position shift distance. The position
after the shifts is set as the home position.
Performs homing with reference to the first
Z-phase in the direction of the dog front
end.
The position specified by the first Z-phase
signal or the position of the first Z-phase
signal shifted by the home position shift
distance is used as the home position.
After the reverse rotation stroke end is
detected, the position moves in the
opposite direction. Then, the position
specified by either the first Z-phase signal
after leaving the stroke end or the position
of the first Z-phase signal shifted by the
home position shift distance can be set as
the home position.
If the position is shifted in the forward
rotation direction, and the forward rotation
stroke end is detected before the Z-phase
signal is detected, [AL. 090 Homing
incomplete warning] will occur.
When FLS/RLS is used, this homing
method is available on servo amplifiers
with firmware version C0 or later.
