User’s Guide for EM760 series high-performance vector inverter ⚫ Prior to self-identification, make sure that the motor is stopped; otherwise, self-identification cannot be performed properly. Parameter identification steps ⚫ Where the motor and load can be separated, the mechanical load and motor should be completely separated in the power-off status. ⚫ After the power-on, set the command source of the inverter to keyboard control (F00.02=0). ⚫ Enter the nameplate parameters of the motor accurately. ⚫ For the asynchronous motor: Set F01.34=1 for confirmation and press the RUN key. The inverter will start the static self-identification of the motor.
Set F01.34=2, make confirmation and press the RUN key. The inverter will start rotation self-identification of the motor. Set F01.34=3, make confirmation and press the RUN key. The inverter will start encoder self-identification of the motor and encoder. ⚫ For the synchronous motor: Set F01.34=11, make confirmation and press the RUN key. The inverter will start stillness self-identification of the motor. Set F01.34=12, make confirmation and press the RUN key. The inverter will start rotation self-identification of the motor. Set F01.34=13, make confirmation and press the RUN key. The inverter will start encoder self-identification of the motor and encoder.
⚫ It takes about two minutes to complete the self-identification of the motor. Then the system will return to the initial power-on status from the “tune” interface. ⚫ If multiple motors are used in parallel, the rated power and rated current input of the motors should be the sum of power and current of these motors. If two motors are used alternately, the parameters of the motor 2 in the F14 group need to be set separately, and identified based on F14.34. 39 Static self-learning of synchronous motor F01.34=2 Rotary self-learning of asynchronous motor Scenarios where the motor and load can be separated easily and open-loop control is adopted.
Before operation, the motor shaft should be separated from the load. The motor under load must not be put into rotary self-learning. Good F01.34=12 Rotary self-learning of synchronous motor F01.34=3 Self-learning of asynchronous motor encoder Closed-loop control; scenarios where the motor and load can be separated easily and closed-loop control is adopted.
