The function is used to suppress fixed oscillation while inverter
is match for motor . If output current varied again and again
while constant load running ,you can adjust the function code
that is base on the factory default value to eliminate oscillation
and make the motor running on an even keel .
This function is used to adjust the carrier frequency of the
inverter . By adjusting the carrier frequency , the motor noise
can be reduced , and the resonance of the mechanical system
can be avoided , so that the leakage current to the earth and
the interference of the inverter can be reduced .
When the carrier frequency is low , the output current higher
harmonic component will increase , the loss of will
increase , and the motor temperature will also
motor
rise increase.
When the carrier frequency is high , the motor is
reduced , and the motor temperature is decreased , but the
inverter and its temperature rise will increase
and so will the interference .

AVR is output voltage regulate automatically , that means
inverter adjusts
and keep the output voltage stable so as to
overcome motor radiation for higher output voltage and
power shortage for lower output voltage. The parameter
can choose the effective session of AVR.

When deceleration stopped , AVR selection disabled ,
deceleration time will shorten but running current will
become larger ,when AVR selection enabled , deceleration
time will lengthen but running current will decrease .

When the carrier wave temperature adjustment is enabled ,
the inverter can automatically adjust the carrier frequency
according to its temperature . This function can reduce the
possibility of over heat alarm of the inverter .

Function
Even if there is signal input , the
inverter still has no action . The no
operation function can be set on the
unused terminals so as to prevent
error action .
It can realize 16S speed through the
combination of digital status of
these four terminals .
Details about the combination refers
to attached figure 1 .
This terminal is used to realize
three-line control mode of
terminal command. As for detailed
description, please refer to
F3.06 function code .
