8. Parameters
z Zone boundary (1: No. 1/2 ZONM/ZONL 2: No. 23/24 ZNM2/ZNL2)
These parameters set the range where the zone output signal (ZONE1) is turned ON when the PIO pattern 0
[Positioning mode (standard type)], 4 [Solenoid valve mode 1 (7-point type)], or 5 [Solenoid valve mode 2 (3-
point type)] is selected.
The zone output signal turns ON when the current position is between the negative-side boundary and positive-
side boundary. Set the positive-side boundary in parameter No. 1, and negative-side boundary in No. 2.
The minimum setting unit is “0.01 [mm].”
Example) To turn ON the ZONE1 signal when the actuator with a 300-mm stroke enters the section of 100 to
200 mm, set 200.00 in parameter No. 1 (Zone boundary+) and 100.00 in parameter No. 2 (Zone
boundary-).
(Note) This controller does not use parameter No. 23 (Zone boundary 2+) and parameter No. 24 (Zone
boundary 2-).
z Home return direction (No. 5 ORG)
Unless specified by the user, the home return direction is set to the motor direction at the factory.
Should a need arise to change the home direction after the actuator has been assembled into your system,
reverse the setting in parameter No. 5 between “0” and “1.”
If necessary, also change the home return offset, soft limit and excited-phase signal detection direction
parameters.
Caution: The home direction cannot be reversed for a rod-type actuator.
z 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 conditions:
[1] Want to align the actuator home and the system’s 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.
