the setting value of the current parameter being changed exceeds
its upper limit value as a result of another parameter setting value
being changed. (In the latter case, the value will be corrected to its
upper limit value.)
L 0 alarm (lower limit alarm) ... When the lower limit ofthe setting range has been reached, or when
the setting value of the current parameter being changed exceeds
its lower limit value as a result of another parameter setting value
being changed. (In the latter case, the value will be corrected to its
lower limit value.)
