5-3 Parameter Settings
If you have changed any parameter, be sure to restart the controller via a software reset or reconnect the
controller power.
5-3-1 Parameters Relating to Actuator Stroke Range
 Soft limits
Set the + soft limit in parameter No. 3 and – soft limit in parameter No. 4.
Both parameters have been set to the effective actuator length at the factory. Change the parameter settings if
necessary, such as when an obstacle is present and collision between the actuator and obstacle must be
prevented or when the actuator must be operated beyond the effective length.
Exercise due caution when setting these parameters, as wrong settings will cause collision with the mechanical
end.
The minimum setting unit is 0.01 mm.
(Note) To change these parameters, set values corresponding to positions that are 0.3 mm wider than the
desired effective range.
Example) Set the effective range to between 0 and 80 mm
Parameter No. 3 (+ side): 80.3
Parameter No. 4 (– side): -0.3
 Zone limits
Set the zone in which the zone output signal turns ON.
The zone signal will turn ON when the current coordinate is between the – setting and + setting.
Set the + zone limit in parameter No. 1 and – zone limit in parameter No. 2.
The minimum setting unit is 0.01 mm.
Example) With the actuator of 300-mm stroke, use the zone limits as an intermediate LS actuating in a range
of 100 to 200 mm
Parameter No. 1 (+ side): 200 Parameter No. 2 (– side): 100
 Home direction
If not specified by the user, the home direction is set to the motor side before shipment.
If you must change the home direction after the actuator has been assembled to your equipment, switch 0 and 1
in the setting of parameter No. 5.
If necessary, also change the home offset and soft limits.
Caution: Rod-type actuators do not permit reversing of the home direction.
If the home direction is reversed, all position data currently input will be cleared.
