[14] Home Sensor Polarity (Parameter No. 18)
No. Name Unit Input range
Default initial value setting
18 Home sensor polarity - 0 to 2 In accordance with actuator
A parameter to select input polarity of the home sensor.
Home sensor is optional.
Set value Content
0
Standard specification
(home sensor not in use)
1 Input is a-contact
2 Input is b-contact
[15] Select enable/disable servo ON input (Parameter No.21)
No. Name Unit Input range
Default initial value setting
21
Select enable/disable servo
ON input
0 : Enabling
1 : Disabling
0
This parameter defines whether the servo ON input signal is disabled or enabled.
When the servo ON input signal is disabled, the servo is turned ON as soon as the controller
power is turned ON.
Set this parameter to “1” if servo ON/OFF is not provided by PIO signals.
6.1 Parameter
ME0342-4B 6-16
[16] 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.
