In accordance
with actuator
In this setting can set the distance from the mechanical end to the home position.
An adjustment is available for the following cases.
1) Want to match the actuator home position and the mechanical origin of the system.
2) Want to set a new home after reversing the factory-set home direction.
3) Want to eliminate a slight deviation from the previous home position generated after
replacing the actuator.
[Adjustment Process]
1) Homing execution
2) Offset check
3) Parameter setting change
4) If setting a number close to a multiple of the lead length (including home-return offset value =
0) to the home offset value, there is a possibility to servo lock on Z-phase at absolute reset,
thus the coordinates may get shifted for the lead length.
For Absolute Type, do not attempt to set a value near a number that the lead length is
multiplied by an integral number.
Have enough margin.
After the setting, repeat home return several times to confirm that the actuator always
returns to the same home position.
Caution: If the home return offset has been changed, the soft limit parameters must
also be adjusted accordingly.
In case the there is a necessity of setting a value more than the initial setting,
contact IAI.
