Analog Function Summary Table – This table shows both functions for the analog 
voltage output [AM] terminal, configured by C028. More information on using and 
calibrating the [AM] output terminal is in 
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 available on other functions).
The frequency arrival signal, [FA1] or 
[FA2], 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 accel-
eration and deceleration ramps, C042 and 
C043.
