Home Return Offset (No. 22, OFST)
Parameter No. 22 has been set to an optimal value at the factory so that the distance from the mechanical end to home will
remain constant.
The minimum setting unit is 0.01 mm.
This parameter can be adjusted in the following conditions:
[1] Align the actuator's home with the mechanical home on the equipment after the actuator has been assembled to the
equipment.
[2] Set the home position again after reversing the factory-set home direction.
[3] Correct the minor position deviation that has generated after the actuator was replaced.
Caution
If you have changed the home return offset, the soft limit parameters must also be reviewed.
Zone Boundaries (1: Nos. 1/2, ZONM/ZONL; 2: Nos. 23/24, ZNM2/ ZNL2)
Set the zone within which the zone output signal (ZONE1 or ZONE2) turns ON.
The zone signal turns ON when the actuator coordinate is inside the range set by the (-) boundary and (+) boundary.
For the ZONE1 signal, set the + boundary in parameter No. 1 and – boundary in parameter No. 2.
For the ZONE2 signal, set the + boundary in parameter No. 23 and – boundary in parameter No. 24.
The minimum setting unit is 0.01 mm.
Example) Use ZONE1 as an intermediate LS actuating in a range of 100 to 200 mm, and ZONE2 as a simple ruler
actuating in a range of 270 to 275 mm, for a 300 mm stroke actuator.
