Low Load Detection Parameters
The following
conjunction with the intelligent output
function, when configured. The output
mode parameter (C038) sets the mode of
the detection at which the low load
detection signal [LOC] turns ON. Three
kinds of modes can be selected. The
detection level parameter (C039) is to set
the level of the low load.
This function is for generating an early
warning logic output, without causing
either a trip event or a restriction of the
motor current (those effects are available
on other functions).
