Chapter 3: Operation
31
Three-level menu:
1 The function code group (first menu);
2. Function code (second menu);
3. Function code set value (third menu).
Explanation: the three-level menu operation can press PRG or ENTTER to return to the
secondary menu. The difference between these two manners is next: press ENTER to set
parameters in control panel, and then return to the secondary menu, and automatically
move to the next function code; Press PRG directly to return to the secondary menu,
don’t store parameters, and keep staying in the current function code. Example: change
the function code P1.03 from 00.00 Hz change the sample set to 50.00 Hz.
In three-level state, if the parameter is not flashing, it means that the function code
cannot be modified, possible reasons are:
1) The function code parameters cannot be modified. Such as the actual testing
parameters, operation records, etc.;
2) The function code in the running state cannot be modified.
Fault RESET
After the failure of the inverter, the inverter will be prompted to related fault
information. User can press STOP key on the keyboard or by terminal function reset the
fault (P5), after fault reset the inverter is in the standby mode. If the inverter is in fault
state, the user does not carry on the fault reset, the inverter is in the running to protect
state and can't run.
Adaptive motor parameters setting
1: Automatically setting the dynamic parameters
When selecting vector control mode PG, the motor nameplate data must be exactly
entered, the inverter will be set according to the nameplate parameters that correspond
to the standard motor. In order to get better control performance, motor parameter
auto-tuning is suggested and auto-tuning steps are as follows:
First, the command channel selection (P2.00) for the key commands is started. Then
enter the actual parameters according to the engine, as follows: P2.00: engine type;
P2.01: the motor rated power;
P2.02: the motor rated voltage;
P2.03: the motor rated current;
P2.04: the motor rated frequency;
P2.05: the motor rated speed.
In the automatic setup process, "Study" appears on the display, when the display shows
"END" the automatic parameter setting of the motor is terminated.
NOTE: In an automatic tuning process, the motor should be unloaded, otherwise the
motor parameters obtained from the automatic tuning may not be correct.
2: Automatically setting the static parameters
During auto-tuning of the static engine parameters, the motor may not be without load,
the input parameters (P2.01 - P2.05) must be corrected according to the motor
