AVR means automatic voltage regulation.
The function can regulate the output voltage and make it
constant. Therefore, generally AVR function should be
enabled, especially when the input voltage is higher than
the rated voltage.
In Dec-to-stop process, if AVR function is disabled, the
Dec time is short but the operating current is big. If AVR
function is enabled all the time, the motor decelerates
steadily, the operating current is small but the Dec time
is prolonged.

Note:
1.The carrier wave frequency will affect the noise when
motor running,generally the carrier wave frequency is
supposed to set as 3~5KHz.For some special situation
where require operating mutely,the carrier wave
frequency is supposed to set as 6~8KHz.
2．When set the carrier wave frequency larger than
defaultvalue,then the power of drive need to derate 5%
by every increase of 1KHz.

During deceleration, the motor’s decelerate rate may be
lower than that of drive’s output frequency due to the
load inertia. At this time, the motor will feed the energy
back to the drive, resulting in the voltage rise on the
drive's DC bus. If no measures taken, the drive will trip
due to over voltage.
During the deceleration, the drive detects the bus voltage
and compares it with the over voltage point at stall
defined by b2.03. If the bus voltage exceeds the stall
overvoltage point, the drive will stop reducing its output
frequency. When the bus voltage become lower than the
point, the deceleration continues, as shown in Fig.6-37.
The hundred’s place is used to set overmodulation
function of V/F control.For vector control,the
overmodulation function will be always
enable.Overmodulation means when the voltage of
power grid is low for long term(Lower than 15% of
rated voltage),or is overload working for long term,then
the drives will increase the use ratio of its own bus
voltage to increase output voltage.
