Detail Explanation of Parameters
If you have changed any parameter, be sure to restart the controller via a software reset or reconnect the controller
power.
5.2.1
Parameters Relating to Actuator Stroke Range
z Soft Limits (No. 3 LIMM) (No. 4 LIML)
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
z Software limit margin (No. 88 SWLM)
If the actuator goes outside the range defined by the soft limits, a “Software limit over error” occurs.
By setting parameter No. 88, you can disable the detection of this error for the dimension corresponding to the value
set in parameter No. 88 from each soft limit.
The minimum setting range is 0.01 mm.
