Figure 5.2 Flow chart of parameter setting.
Under the third-class menu, if the parameter has no flickering bit, it means the function
code cannot be modified. The possible reasons could be:
z
This function code is not modifiable parameter, such as actual detected parameter,
operation records and so on;
z
This function code is not modifiable in running status, but modifiable in stop status
5.2.2 Fault reset
If the inverter has fault, it will prompt the related fault information. User can use
STOP/RST or according terminals determined by P5 Group to reset the fault. After fault
reset, the inverter is at stand-by state. If user does not reset the inverter when it is at fault
state, the inverter will be at operation protection state, and can not run.
5.2.3 Motor parameter autotuning
If “Sensorless Vector Control” mode is chosen, motor nameplate parameters must be
input correctly as the autotuning is based on it. The performance of vector control
depends on the parameters of motor strongly, so to achieve excellent performance, firstly
must obtain the parameter of motor exactly.
The procedure of motor parameter autotuning is as follows:
Firstly, choose the keypad command channel as the operation command channel
(P0.01).
And then input following parameters according to the actual motor parameters:
P2.00: motor rated power.
P2.01: motor rated frequency;
P2.02: motor rated speed;
P2.03: motor rated voltage;
P2.04: motor rated current
Notice: the motor should be uncoupled with its load; otherwise, the motor
parameters obtained by autotuning may be not correct.
Set P0.12 to be 1, and for the detail process of motor parameter autotuning, please refer
to the description of Function Code P0.12. And then press RUN on the keypad panel, the
inverter will automatically calculate following parameter of the motor:
