(15) Home return offset level (Parameter No.22)
No. Name Symbol Unit Input Range Default factory setting
22 Home return offset level OFST mm 0.00 to 9999.99
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) After the setting, repeat home return several times to confirm that the actuator always
returns to the same home position.
Caution : x Soft limit takes the home position as the datum. Therefore, when a change
is made to the value of home-return offset level, also revise the value for
soft limit.
x If the home return offset has been changed, the soft limit parameters must
also be adjusted accordingly.
Do not set a smaller value than the initial setting value for Home Return
Offset. Normal excitation detection cannot be performed, and there may be
a risk of generating the excitation detection error or causing abnormal
noise.
In case the there is a necessity of setting a value less than the initial
setting, contact IAI.
