3.2 Detail Explanation of Parameters

If a parameter has been changed, always restart the controller using a software reset command or by
reconnecting the power.

3.2.1

Parameters Relating to the Actuator Stroke Range

 Soft limit

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 crash with an obstacle or when the actuator must be stroked slightly beyond its effective length.
A wrong soft limit setting will cause the actuator to crash into the mechanical end, so exercise due 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















 Software limit margin (No. 88 SWLM)

If the actuator exceeds the soft limit, a “software limit over error” occurs.
By setting parameter No. 88, it is possible to disable detection of setting value errors from the soft limit to

parameter No. 88. The minimum setting range is 0.01 mm.
