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.
3) To invalidate the software stroke limit, set the setting value to "upper limit
value = lower limit value". (The setting value can be anything.)
4) When the unit is "degree", the software stroke limit check is invalid during
speed control (including speed-position switching control, position-speed
switching control) or during manual control.
Set whether to apply the software stroke limit on the "current feed value" or the
"machine feed value". The software stroke limit will be validated according to the
set value.
Set whether to validate the software stroke limit during JOG/Inching operation and
manual pulse generator operation.
Setting value, setting range
Value set with peripheral device
The setting value range differs depending on the "

Set the remaining distance that turns the command in-position ON. The command
in-position signal is used as a front-loading signal of the positioning complete
signal. When positioning control is started, the "command in-position flag" (3rd flag
Md.31
from right) in " Status" turns OFF, and the "command in-position flag" turns
ON at the set position of the command in-position signal.
