AVR means automatic voltage adjustment, when there is deviation between voltage
input and rated value of the inverter, it can through this function to ensure stable
voltage output of the inverter, however it will be invalid if the value of voltage output
bigger than input voltage of power supply. During decelerating, if no action of AVR,
the deceleration time is short and running current is big; if action of AVR, motor
deceleration is placid and running current is small, but the deceleration time will be
long.
P2.09 Automatic energy-saving operation
Setting range
0：Inhibitive
1：Allowable
If the inverter is under automatic energy-saving operation, it will automatically check
the load situation and adjust voltage output in order to make the motor in high effect
energy saving status.
The energy saving effect is much evident if the load's variation frequency is low and
scope is large. The work principle is that adjusting motor excitation state make the
motor work in a state of optimal efficiency under the light loads,and maximum limit
reduces the energy consumption of the motor and gain additional energy saving effect.
Note: This function is mainly fit for loads of fan and pump.
Forward and reverser rotation
P2.10
dead-zone interval
Setting range
When the inverter receives Reverser rotation command when inverter is running, it
will run from the present direction to the opposite. The interval is the waiting
transition time when the inverter outputs zero frequency during the above process,
