5. Parameter Settings

Home return offset (No. 22 OFST)

The controller is shipped from the factory with an optimal value set in parameter No. 22, so the distance from
each mechanical end to the home becomes uniform.
The minimum setting unit is 0.01 [mm].
The home return offset can be adjusted in the following condition:
>@ :DQWWRDOLJQWKHDFWXDWRUKRPHDQGWKHV\VWHP¶V mechanical home after the actuator has been assembled

into the system

[2] Want to set a new home after reversing the factory-set home direction
[3] Want to eliminate a slight deviation generated after replacing the actuator

Caution: If the home return offset has been changed, the soft limit parameters must also be adjusted

accordingly.

Zone boundary (1: No. 1/2 ZONM/ZONL, 2: No. 23/24 ZNM2/ZNL2)

Set the zone in which a zone output signal (ZONE1 or ZONE2) will turn ON.
The zone signal turns ON only when the current coordinate position is inside the negative (-) boundary and
positive (+) boundary settings.
The positive and negative boundaries for the ZONE1 signal are set in parameter No. 1 and No. 2, respectively.
The positive and negative boundaries for the ZONE2 signal are set in parameter No. 23 and No. 24, respectively.
The minimum setting unit is 0.01 [mm].

Example) Use ZONE1 as an intermediate limit switch inside 100 and 200 mm, and use ZONE2 as a simple ruler

inside 270 and 275mm, with an actuator having a 300 mm stroke
Parameter No. 1 (positive side) 200, parameter No. 2 (negative side) 100
Parameter No. 23 (positive side) 275, parameter No. 24 (negative side) 270

* The functions have been changed in the new version. Refer to

the notes provided at the beginning of the manual.
