b) Parameter setting:
Number of speed levels: 2⁴=16 levels (4 switches)
Steps to adjust parameters:
Press the MENU key to access functions, use the arrow keys to change functions and the DATA key to save setting values.
Step 1:

Function	Setting value	Meaning
FF-01	1	Reset parameters for inverter
F0-01	0	Set up push button control on the inverter (Run/Stop button)
F0-02	6	Motor control runs at 16 speed levels
F0-10	50	Maximum frequency of inverter operation

Step 2:

Function	Setting value	Meaning
F2-00	1	Set engine parameters
F2-01	373	Engine power parameters (default engine power)
F2-02	380 (V)	Motor voltage parameters
F2-03	1.2 (A)	Engine current parameters
F2-04	50 (Hz)	Frequency of the motor
