5.1.7 Low-cut Function Setting
A low-cut value can be set for the frequency output, pulse output and totalizer.
Ifthelow-cutfunctionisused,theowratebelowsetpontscanbestoppedfrombeingoutput.
Thisfunctionhelpsreduceerroneousoutputwhentheowrateis“0”.
However, the unit of the low-cut value is the unit set in Subsection 5.1.4. If the unit is changed,
the low-cut value is changed to the converted value in conjunction with the unit.
Setthelow-cutvalueto“0”ifthelow-cutfunctionisnotused.
Thesettingcanbeconguredwiththefollowingparameters.

Asforlow-cutsettingsoftheoutputsignal(LOW_CUT),theoutputismadeto0iftheoutput
goes below the low-cut setpoint.
Toenablethelow-cutfunction,the“Lowcuto󰀨”optionshouldbeenabledwithIO_OPTS.
However, when the status returns from the low-cut state to the normal state, hysteresis is waited.
When the L_TYPE setting of the output mode is direct, the hysteresis width is 1% of XD_SCALE,
and otherwise, the width is 1% of OUT_SCALE.
