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 “
Analog Output Operation” on page 4–55.
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.
09 LOG Logic Output
Function
ON when the Boolean operation specified by C143
has a logical “1” result
