different from the factory settings.
◆ When the technical personnel perform onsite maintenance, use this mode to conveniently record
and query the modified parameters.
◆ After the inverter commissioning is completed, to conveniently record and query the modified
parameters, this mode can be set.
3： Menu mode of last changed 10 function codes: When the inverter has abnormal operation or it is
necessary to inquire the commissioning parameters, the last changed 10 parameters can be queried by
setting this menu mode. When the factory settings are recovered, the record of the last changed 10 function
codes will also be cleared.
Note:
◆ Both P0.00 and P0.02 are visible in all the menu display modes for the convenience of menu
mode switching.
◆ Press ESC key and hold for over 5 seconds, it will restore to basic menu mode, and P0.02 is
automatically restored to 0.
◆ In non−basic menu mode, the >> key cannot be used to switch the function zone code and
group number. The current menu mode will be displayed after pressing the >> key slowly for
several times.
P0.03
This function is used to set the control operation mode of the inverter.
0: Process open loop control: It is applicable to most applications, including the application of one
inverter driving one motor and the application of one inverter driving multiple motors (the motors are in
the same work conditions).
1: Analog value feedback process close loop control: It is applicable to applications with general
requirement of speed control precision. The feedback analog can represent such parameters as
temperature, pressure and humidity. For the reference and feedback setting of the analog feedback
process close loop control, refer to P1.02~P1.07 function description. For the setting of the process PID
close loop parameters, refer to Group P8 function code description.
AI1 and AI2 terminal input specification: 0~10V or 0~20mA.
P0.04
P0.05
This function is applicable to the frequency reference of open loop control mode. For the speed reference
of process close loop control mode, refer to the descriptions of function code of Group P1.
0: Set frequency reference via P0.05.
Note: If multi−section digital voltage terminals 1 ~ 3 are enabled, the frequency is determined by the
terminal combination. Refer to P4.15
