4.8.8 Multi-Speed Mode
In scenarios where the running frequency of the AC drive need not be adjusted continuously
and only several frequencies are required, the multi-speed control can be used. The
MD380 supports a maximum of 16 running frequencies, which are implemented by state
combinations of four DI terminals. Set the function codes corresponding to DI terminals to a

terminals. The multiple frequencies are set based on the multi-frequency table in group
FC. In addition, you need to set F0-03 (Main frequency source X selection) to 6 (Multi-

In the preceding figure, DI7, DI4, DI8, and DI2 are used as the multi-frequency input
terminals, each of which has a bit value. The state combinations of these terminals

combination value is 2, corresponding to the value set in FC-02. The frequency reference is
automatically calculated by FC-02 x F0-10.
The MD380 supports a maximum of four DI terminals to be used as the multi-frequency
input terminals. You can also use less than four DI terminals, and the empty bit is considered
to be 0.
