[Homing offset (Parameter No. 22)]
No. Name Unit Input range Default initial value setting
22 Homing offset
mm
(deg)
0.00 to 9,999.99 In accordance with actuator
Sets the distance from the mechanical end to the home position.
Home is adjustable in the following cases.
·To match the actuator home position and the mechanical home position after assembly into
equipment.
·To set a new home position after reversing the default home direction.
·To eliminate a slight deviation from the previous home position generated after replacing the
actuator.
Adjustment process
(1) Perform home return motion.
(2) Check amount of deviation.
(3) Change the parameter.
(4) After setting, repeat home return motion several times to confirm that the actuator always
returns to the same home position.
Caution
● If the homing offset has been changed, the software limit parameter also needs to be
reviewed.
If the value must be set above the default setting, contact IAI.
● For the absolute specification, if a value close to an integral multiplication of the lead
length (including homing offset 0) is set for the homing offset, servo lock status may
ensue in the Z-phase during the absolute reset, and coordinates may deviate by the
lead length.
● For absolute specification, never set a value close to an integral multiplication of the
lead length. Secure sufficient margin.
