Output Function 
Adjustment 
Parameters
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.
