5.2 Parameter Settings
If a parameter has been changed, always restart the controller using a software reset command or by
reconnecting the power.
5.2.1 Parameters Relating to the Actuator Stroke Range
Ɣ Soft limit (No. 3/4 LIMM/LIML)
Set the soft limit in the positive direction in parameter No. 3, and that in the negative direction in parameter No. 4.
The factory setting for the soft limits conforms to the effective actuator length. Change the settings, as necessary,
to prevent collision with an obstacle or when the actuator must be stroked slightly beyond its effective length.
An incorrect soft limit setting will cause the actuator to collide into the mechanical end, so exercise sufficient
caution. The minimum setting unit is “0.01 [mm].”
(Note) To change a soft limit, set a value corresponding to 0.3 mm outside of the effective range.
Example) Set the effective range to between 0 mm and 80 mm
Parameter No. 3 (positive side) 80.3
Parameter No. 4 (negative side) -0.3
Ɣ 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.”
Also change the parameters for home return offset, soft limits and direction of excited phase signal detection if
necessary.
Caution: If the home direction is reversed, all position data that have been input will be retained.
The home direction cannot be reversed for rod-type actuators.
