If the carrier frequency’s lower bound (Pr. 00-16) > the carrier frequency’s upper bound
(Pr. 00-15), then the carrier frequency will be operated at the upper boun
d level.

Auto Voltage Regulation (AVR) Function
Factory setting 0
Settings
0 AVR function enabled
1 AVR function disabled
2 AVR function disabled during deceleration
1
This parameter selects the AVR mode. AVR is used to regulate the output voltage to
the motor.
1
The input voltage to the AC motor drive could range from AC180V-264V at, 50Hz/60Hz.
When this occurs, the output voltage to the motor will also vary from 180 to 264 unless
the AVR function is enabled. When enabled, the AVR function will limit the voltage to the
motor, based on Pr. 01-02.

Automatic Energy-Saving Operation
Factory setting 00010
Settings
Bit 0 0 Disable automatic energy-saving operation
1 Enable automatic energy-saving operation
Bit 1 0 Maximum output voltage equals to the input power voltage
1
Maximum output voltage could be greater than the input power
voltage (over-modulation available)
1
When the Auto Energy-Saving function is enabled, the drive will operate with full voltage
during acceleration and deceleration. At constant speed the AC drive will calculate the
optimal output voltage value for the load. It is possible for the output voltage to be 25%
below Maximum Output Voltage during auto energy saving operation. This function
should not be used with variable loads or continuous rated output loads. During these
types of conditions, the operation will cycle on and off, giving poor energy saving results.
