Conditions for erasing absolute position data
For an incremental system, the absolute position data is erased in the following situations:
• If homing is not being executed.
• If homing is in progress.
• If [AL. 069 Command error] occurs.
For an absolute position detection system, the absolute position data is erased in the following situations:
• If homing is not being executed.
• If homing is in progress.
• If [AL. 069 Command error] occurs.
• If [AL. 025 Absolute position erased] or [AL. 0E3 Absolute position counter warning] occurs.
• If the electronic gear ([Pr. PA06] or [Pr. PA07]) is changed.
• If the setting for [Pr. PA03.0 Absolute position detection system selection] is changed from "Disabled" to "Enabled".
• If [Pr. PA14 Travel direction selection] is changed.
• If [Pr. PA01.1 Operation mode] is changed.
19 Homing without index pulse Forward rotation This is the same as the dog type front end reference homing.
Note that if the stroke end is detected during homing, [AL. 090 Homing
incomplete warning] occurs.
20 Homing without index pulse Forward rotation Although this type is the same as the dog cradle type homing, 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 homing, [AL. 090 Homing incomplete
warning] occurs.
21 Homing without index pulse Reverse rotation This is the same as the dog type front end reference homing.
Note that if the stroke end is detected during homing, [AL. 090 Homing
incomplete warning] occurs.
22 Homing without index pulse Reverse rotation Although this type is the same as the dog cradle type homing, 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 homing, [AL. 090 Homing incomplete
warning] occurs.
23 Homing without index pulse Forward rotation This is the same as the dog type front end reference homing.
24 Homing without index pulse Forward rotation Although this type is the same as the dog cradle type homing, 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 This is the same as the dog type front end reference homing.
28 Homing without index pulse Reverse rotation Although this type is the same as the dog cradle type homing, 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 homing, 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 homing, 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 type can be executed even
when the servo amplifier is not in the Operational enabled state.
37 Homing on current position

The current position is set as the home position. This type can be executed even
when the servo amplifier is not in the Operational enabled state.
