Output Function Adjustment Parameters
The following parameters work in
conjunction with the intelligent output
function, when configured. The overload
level parameter (C_41) 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, C_42 and
C_43.
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.
