8.2.10 frequency command limit (frequency setting )
Operating frequency upper limit: limit the maximum output frequency, and the motor is not allowed to
run above a certain frequency;
Lower limit of operating frequency: limit the minimum output frequency, and do not allow the motor to
run below a certain frequency;
Maximum output frequency: limit the maximum output frequency.

8.3 Start and stop method setting
8.3.1 Start method
There are three starting methods for the inverter, which are: start from the starting frequency , brake first
and then start from the starting frequency, and start after speed tracking . Set parameter F1.00 to select the
starting method of the inverter .
8.2.7 Communication setting main frequency
See Chapter 9 RS485- Modbus communication instructions for details .
8.2.8 Input setting of auxiliary frequency command
Set parameter F0.03 to select the auxiliary frequency command input, which is the same as the main
frequency command input selection method, the specific parameter selection and setting process can refer to
"8.2.1 Select the input method of the main frequency command".
8.2.9 Select main and auxiliary frequency superposition command
The relationship between the target frequency and the main and auxiliary frequency commands can be set
by parameter F0.04 .
