Analog filtering time constant must be bigger than F3.11(sampling cycle),
otherwise the system would run unsteadily.
F2.01 FWD REV run dead-section time
During process of transiting from forward run to reverse run or from reverse run
to forward run, transition time during which the inverter wait at zero output
frequency, as t1 shown in Fig.6-9.
F2.02 Automatic energy save run
To reach better energy save result, the inverter would detect load current to get
the purpose of automatic energy save.
0: no action
1: action
Empty or lightly loaded motor can get the purpose of energy save by detecting
load current to adjust output voltage properly. Automatic energy save run is mainly
applied to occasion of stable load, speed.
This function commonly applied to load such as blower and water pump etc.
note
F2.03 AVR function
AVR namely automatic voltage adjusting function. Indicate that the inverter can
output constant voltage by AVR function when the inverter input voltage fluctuates.
0: no action
1: action all the time
2: no action only during Dec
1. when input voltage is higher than rated value, under normal situation should set F2.03=1. When F1.05=0
namely inverter in decelerating stop， motor Dec time is short and running current would be bigger. But the
motor decrease speed placidly with small run current and long Dec time if choose AVR action all the time.
note
2. should set F2.03=0, namely AVR function ineffective when the motor system oscillates which caused by
choosing AVR function.
