First, communication start and stop + communication given frequency case

1. Connect the communication line and fault output signal line connected to the air compressor controller according to Figure 1-1.

2. P0-17=1, restore the inverter parameters to factory settings.

3. Set the following parameters and perform static self-learning of parameters.

Function code setting function

F0.07150 maximum output frequency (set according to actual conditions)

F0.08150 operating frequency upper limit

F2.111 permanent magnet synchronous motor

F2.0122 motor rated power (set according to motor nameplate)

F2.02150 motor rated frequency (set according to motor nameplate)

F2.033000 motor rated speed (set according to the motor nameplate)

F2.04380 motor rated voltage (set according to motor nameplate)

F2.0540 motor rated current (set according to the motor nameplate)

F2.15338 motor back electromotive force constant (set according to motor nameplate)

Set P0.16 to 1, and press the 'RUN' run key to perform parameter self-learning.

4. Confirm the direction of motor rotation. Press the “JOG” button to check the direction of rotation of the motor. If the direction is wrong, replace any two-phase inverter output line.

5. Set the inverter parameters.

Function code setting function

F0.012 communication running command channel

F0.027 remote communication given frequency

F6.044 fault output (normally closed)
