When motor is running with light load or no-load, the inverter will detect the load current and
adjust output voltage appropriately so as to save energy. This function is mainly used in
application with stable load and running speed.
P3.04
AVR function
Range: 0, 1, 2
0
This is auto voltage regulation function. When inverter input voltage is fluctuating, use this
function to keep inverter output voltage stable.
When inverter is decelerating to stop, if AVR function is invalid, the Dec. Time is going to be
shorter. But it will output a higher running current. If AVR is effective, the motor will be
decelerating stably with lower running current, but the Dec. Time becomes longer

This function can regulate the output frequency appropriately according to the load, which
can dynamically compensate the slip frequency of asynchronous motor so as to control the
speed at a stable value. If use this function in conjunction with auto. torque boost function, It
can achieve better low speed torque characteristic, which is shown as Fig.6-13
