Recovery of function
parameter
0: No operation
1: Recover default value beside
the group of electric machine
parameter
2: Recover default value
including the group of electric
machine parameter
3: Eliminate fault files
□
0: No operation
1.AC frequency vector inverter recovers default value for all parameters (beside P03 group).
2.AC frequency vector inverter recovers default value for all parameters (including P03 group).
3.AC frequency vector inverter eliminates recent fault files.
P01.16
Choice of AVR
function
0: Invalid
1: The whole process is effective
2: It is invalid only for
deceleration
◇
AVR function is the automatic adjustment function of output voltage. When AVR function is invalid,
output voltage will change with the change of input voltage (or DC bus voltage); When AVR function is
valid, output voltage will not change with the change of input voltage (or DC bus voltage); and output
voltage will basically keep constant within scope of the output capacity.
Notice: when the motor stops with deceleration, it will automatically stabilize the voltage and AVR
function closes; and it will stop the machine in much shorter time without overvoltage.

P02.00 Start operation mode
0: direct start
1: firstly DC brake and then
start
2: firstly tracking of rotate
speed and the start
□
0: direct start: start with starting the frequency.
1: firstly DC brake and then start: firstly make DC brake based on the setting of P02.03 and P02.04;
and then start with starting the frequency. It is applied to the place with small inertia load; and it may
cause reverse rotation at the start.
2: firstly tracking of rotate speed and the start: AC frequency vector inverter makes speed
identification on the motor which is rotating; and it directly tracks the start for the identified frequency;
during the start process, the current voltage is smooth without any crash.
