2) The function code cannot be modified in the running state. It must be modified while
stopped.

The way to read parameters in various status
In stop or run status, operate shift key
to display a variety of status parameters
respectively. Parameter display selection depends on function code F6.01 (run parameter 1), F6.02
(run parameter 2) and F6.03 (stop parameter 3).
In stop status, there are total 16 stop status parameters that can be set to display/not display:
set frequency, bus voltage, DI input status, DO output status, analog input AI1 voltage, analog
input AI2 voltage, panel potentiometer input voltage, Actual count value, Actual length value, PLC
running step number, Actual speed display, PID settings, high-speed pulse input frequency and
reserve, switch and display the selected parameter by pressing key orderly.
In running status, there are 5 running-status parameters:running frequency,setting
frequency,bus voltage,output voltage, output current default display, and other display parameters:
output power, output torque, DI input status, DO output status, analog input AI1 voltage, analog
input AI2 voltage, panel potentiometer input voltage, Actual count value, Actual length value,
linear speed, PID settings and PID feedback, etc, their display depends on function code F6.01 and
F6.02 switch and display the selected parameter by pressing key orderly.
Inverter powers off and then powers on again, the displayed parameters are the selected
parameters before power-off.

Password settings
The inverter has password protection. When y0.01 become not zero, it is the password and
will be work after exit from function code modified status. Press PRG key again, will display”----”.
One must input the correct password to go to regular menu, otherwise, inaccessible.
To cancel the password protection function, first enter correct password to access and then set
y0.01 to 0.

Motor parameter auto turning
Choose vector control, one must input the motor’s parameters in the nameplate accurately
before running the inverter. ST500 series frequency inverter will match the motor’s standard
parameters according to its nameplate. The vector control is highly depend on motor’s parameters.
The parameters of the controlled motor must be entered accurately for good control performance.
Motor parameter auto tuning steps are as follows:
Firstly select command source (F0.11=0) as the comment channel for operation panel, then
input the following parameters according to the actual motor parameters (selection is based on the
current motor):
Motor Selection
Parameters
Motor
b0.00: motor type selection b0.01: motor rated power
b0.02: motor rated voltage b0.03: motor rated current
b0.04: motor rated frequency b0.05: motor rated speed
For asynchronous motors
If the motor can NOT completely disengage its load, please select 1 (asynchronous motor
parameter static auto tuning) for b0.27, and then press the RUN key on the keyboard panel.
If the motor can completely disengage its load, please select 2 (asynchronous motor parameter
comprehensive auto tuning) for b0.27, and then press the RUN key on the keyboard panel, the
inverter will automatically calculate the motor’s following parameters:
Motor Selection
Parameters
Motor
b0.06:asynchronous motor stator resistance b0.07: asynchronous motor rotor
resistance
b0.08:asynchronous motor leakage inductance b0.09: asynchronous motor
mutual inductance
b0.10: asynchronous motor no-load current
