2. Inverter wiring diagram：
11.3 Multi-speed operation
Assume that a frequency converter needs to adopt the terminal starting mode, and needs to operate at three
different frequencies of 10HZ, 30HZ, and 50HZ. The three frequency switching modes are operated by the X
terminal of the inverter.Firstly, according to the actual motor on site, according to the motor parameters on
the motor nameplate, correctly set to the parameters of the b0 group of the inverter, and make the
corresponding self-learning, and then set the following parameters.
1. Parameter setting
：
A0.02＝0
A0.02 is set to 0 to indicate that the main frequency source is determined by A0.03.
A0.03＝10
A0.03 sets the 10HZ frequency to the third speed. When the X2 and X3 terminals are invalid,
the main reference frequency is 10HZ.
A0.04＝1
Setting A0.04 to 1 indicates that the inverter running command is determined by terminal
control.
A6.00＝01
A6.00 is set to 01, which means that when the X1 terminal is valid, the inverter controls the
motor to run forward.
A6.01＝27
A6.01 is set to 27, which means that when the X2 terminal is valid, the inverter selects the first
speed as the main reference frequency.
A6.02＝28
A6.01 is set to 28, which means that when the X3 terminal is valid, the inverter selects the
second speed as the main reference frequency.
C0.00＝30
C0.00 is set to 30, indicating that the frequency of the first speed is 30HZ.
C0.01＝50
C0.01 is set to 50, indicating that the frequency of the second speed is 50HZ.
