The following parameters work in
conjunction with the intelligent output
function, when configured. The
overload level parameter (C041) sets the
motor current level at which the
overload signal [OL] turns ON. The
range of settings is from 0% to 200% of
the rated current for the inverter. 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 avail-
able on other functions).
The frequency arrival signal, [FA1] to
[FA5], is intended to indicate when the
inverter output has reached (arrived at)
the target frequency. You can adjust the
timing of the leading and trailing edges
of the signal via two parameters specific
to acceleration and deceleration ramps,
C042 and C043.
The Error for the PID loop is the magni-
tude (absolute value) of the difference
between the Setpoint (desired value)
and Process Variable (actual value). The
PID output deviation signal [OD]
(output terminal function option code
04) indicates when the error magnitude
has exceeded a magnitude you define.
