6. Parameter Settings
z Home 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 offset, the soft limit parameters must also be reviewed.
z Zone Limits (1: No. 1/2 ZONM/ZONL
2: No. 23/24 ZNM2/ZNL2)
This parameter is not used with this controller. It applies to controllers of general-purpose and serial communication types.
If this parameter is to be used, set the range within which the zone output signal (ZONE1 or ZONE2) will turn ON.
The zone output signal turns ON when the current coordinate is between the (-) setting and (+) setting.
For the ZONE1 signal, set the positive-side coordinate in Parameter No. 1 and negative-side coordinate in Parameter No. 2.
For the ZONE2 signal, set the positive-side coordinate in Parameter No. 23 and negative-side coordinate in Parameter No. 24.
The minimum setting unit is 0.01 mm.
Example) On an actuator with a 300-mm stroke, ZONE1 is used as an intermediate point LS in a range of 100 to 200
mm, while ZONE2 is used as a simple yardstick in a range of 270 to 275 mm.
Parameter No. 1 (+ side):
200 Parameter No. 2 (– side): 100
Parameter No. 23 (+ side): 275 Parameter No. 24 (– side): 270
