User Manual of EM760 High-Performance Inverter ● Enter the nameplate parameters ofthe 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 ofthe motor. Set F01.34=2, make confirmation and press the RUN key. The inverter will start rotation self- identification ofthe 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 ofthe motor.
Set F01.34=12, make confirmation and press the RUN key. The inverter will start rotation self- identification ofthe 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 ofthe 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 ofthe motor 2 in the F14 group need to be set separately, and identified based on F14.34. 5.8 Closed-loop vector adjustment procedures ● Set the command source of the inverter to keyboard control and the main frequency source to digital frequency F00.07 (5.00Hz); set F12.00 M.K multi-functional key to option: 3 (Forward/Reverse switching); drive control mode of motor F00.01: 0 (VVF).
● Press “RUN” on the keyboard to run the inverter; check F18.02 (PG feedback frequency) - it should fluctuate around 5.00Hz after stabilization; then press M.K to make the inverter run reversely, and after stabilization the feedback frequency should fluctuate around -5.00Hz. Afterwards, set F00.07 to 10.00Hz, 25.00Hz and 50.00Hz successively (make sure it is safe and technologically allowed!) Repeat the above operations. If all goes normal, it means the PG card and encoder are properly wired and set.
● If the motor rotation direction is opposite to the actual direction, please exchange connection of any motor line pair; if the feedback frequency direction of the encoder is opposite to the actual direction (F18.02 and F18.01 are opposite in direction), please exchange the wiring connection of phase A and B on the PG card; if the feedback frequency value is incorrect, please check F01.25 encoder line count. 71 Motor Corresponding Parameter Motor 1 (Motor 2 corresponds to parameters of group F14) F01.00 Motor type F01.01 Rated power of electric motor F01.02 Rated voltage of motor F01.03 Rated current ofmotor F01.04 Rated frequency ofmotor F01.05 Rated speed F01.06: Motor winding connection
