Set the lower limit for the machine's movement range during positioning control.

OP
1) Generally, the OP is set at the lower limit or upper limit of the stroke limit.
2) By setting the upper limit value or lower limit value of the software stroke limit,
overrun can be prevented in the software. However, an emergency stop limit
switch must be installed nearby outside the range.
To invalidate the software stroke limit, set the setting value to "upper limit
value = lower limit value". (If it is within the setting range, the setting value can
be anything.)
When the unit is "degree", the software stroke limit check is invalid during
speed control (including the speed control in speed-position and position-
speed switching control) or during manual control.
