12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
12 - 20
Setting value Home position return types Rotation direction Description
22 Homing without index pulse Reverse rotation
Although this type is the same as the dog cradle type home
position return, the stop position is not on the Z-phase. Starting
from the front end of the dog, the position is shifted by the travel
distance after proximity dog and the home position shift
distance. The position after the shifts is set as the home
position. If the stroke end is detected during home position
return, [AL. 90 Home position return incomplete warning] occurs.
23 Homing without index pulse Forward rotation Same as the dog type front end reference home position return.
24 Homing without index pulse Forward rotation
Although this type is the same as the dog cradle type home
position return, the stop position is not on the Z-phase. Starting
from the front end of the dog, the position is shifted by the travel
distance after proximity dog and the home position shift
distance. The position after the shifts is set as the home
position.
27 Homing without index pulse Reverse rotation Same as the dog type front end reference home position return.
28 Homing without index pulse Reverse rotation
Although this type is the same as the dog cradle type home
position return, the stop position is not on the Z-phase. Starting
from the front end of the dog, the position is shifted by the travel
distance after proximity dog and the home position shift
distance. The position after the shifts is set as the home
position.
33 Homing on index pulse Reverse rotation
Although this type is the same as the dogless Z-phase
reference home position return, the creep speed is applied as
the movement start speed.
34 Homing on index pulse Forward rotation
Although this type is the same as the dogless Z-phase
reference home position return, the creep speed is applied as
the movement start speed.
35 Homing on current position
The current position is set as the home position. This can be
performed even in the servo-off status.
37 Homing on current position
The current position is set as the home position. This can be
performed even in the servo-off status.
(2) Parameters for homing
To perform homing, set each parameter as follows.
(a) Select the homing type and homing direction with [Pr. PT45 Home position return type].
