4.3.2 Extended parameter setting
(1)
Software upper/Lower Limit
(a) The function is designed so that the machine does not execute the positioning operation out of the range by setting
the range of machine available to move through software upper limit and software lower limit. That is, this function is
used to prevent any breakaway by incorrect operation position setting and incorrect operation by user program fault.
(b) External input upper/lower limit can be also set besides the software upper/lower limit.
(c) The range check of software upper/lower limit is done at the start of operation and during operating.
(d) If the software upper/lower limit is detected, error (Software upper limit error: 501, Software lower limit error: 502)
occurs and the pulse output of positioning module shall be disabled.
Therefore, when you want to operate again, it is required to reset error and release the ‘output inhibition’ before using.

* Software upper limit value always should be higher than software lower limit, at least same
(f) If the software upper/lower limit was set by default value (upper limit: 2,147,483,647, lower limit: -2,147,483,648) or
same value, then it wouldn’t detect upper/lower limit.
