A90 series Inverter User Guide Note: Commonly used process parameters may also include input and output terminal function settings, please refer to the function table F02 group and F03 group . 5.7 Motor parameter autotune For better control performance, motor parameter autotune is required. Make sure that motor is in stop status before autotune, otherwise, autotune can not be performed normally. 5.7.1 Steps of Autotune If the motor can be disconnected from load, disconnect motor from load under power off status.
Power on, select command source as Keypad Control (set F00.02=0) Set motor parameters according to the nameplate correctly For asynchronous induction motor By setting F01.34=1, then pressing RUN , inverter starts stationary autotune for motor. Or by setting F01.34=2, then pressing RUN , inverter starts rotational autotune for motor. For permanent-magnet synchronous motor By setting F01.34=11, then pressing , inverter starts stationary autotune for motor. Or by setting F01.34=12, then pressing , inverter starts rotational autotune It takes about 2 minutes to complete the autotune and, afterwards, keypad returns from TUNE to the initial power-on status.
If autotune fails, inverter will display “E24” parameter autotune abnormality. By pressing RESET key, inverter will return to parameter setting status If more than one motor in parallel, input sum of the motor power and sum of the current; If two motors are switched, set the F14 group for motor 2 and do autotune. 31 F00.21 Reverse Control 0: Permit Forward/Reverse 1: Prohibit Reverse 0 〇 Autotune selection Conditon Effect F01.34=1 Asynchronous motor Stationary autotune Stationary autotune is applied to the occasions when motor can not be disconnected from load.
Good F01.34=11 Synchronous motor Stationary autotune F01.34=2 Asynchronous motor rotational autotune Rotational autotune is applied to the occasions when motor can be disconnected from load. Before autotune, motor should be disconnected from load. Never perform rotational autotune for a motor with load. Better F01.34=12 Synchronous motor rotational autotune Motor Corresponding parameters Motor 1 F01.00 Motor type F01.01: Motor rated power F01.02: Motor rated voltage F01.03 Motor rated current F01.04: Motor rated frequency F01.05: Motor rated speed F01.06: Motor wiring method Motor 2 F14.00-F14.06：With the same meaning as above, if need motor 2 RUN UN
