After the functions are set as shown in the table above, press the buttons to operate DI1~DI4 in sequence. The rising edge is effective, and the cycle of each DI terminal is as follows:

The inverter starts running at 30.00 Hz when DI1 triggers the first rising edge, and stops running at the second rising edge.

The inverter starts running at 40.00 Hz when DI2 triggers the first rising edge, and stops running at the second rising edge.

The inverter starts running at 50.00 Hz when DI3 triggers the first rising edge, and stops running at the second rising edge.

When DI4 triggers the first rising edge, the inverter starts running at 30.00 Hz, the second rising edge, the inverter running frequency changes to 40.00 Hz, the third rising edge, the inverter running frequency changes to 50.00 Hz, and the fourth rising edge, the inverter stops;
