Note: The multi-speed symbol defines the operation direction. If it is negative, the operation
direction is reverse. Frequency setting 100.0% is corresponding to maximum frequency(F0.04).
When MI1=MI2=MI3=OFF，the input mode is chosen by F0.03. When terminals MI1、
MI2、MI3 are not all OFF and multi-step speed run, priority of multi-step speed is higher than the
input of keyboard,simulation and communication frequency, through the combined code, 8-step
speed can be chosen at most.

The selection of stop channel starting is also determined by function code F0.01 when
inverter is running at multi- speed, and the multi- speed control process is shown in Fig.6-20.
The relation between MI1、MI2、MI3 terminal and multi-speed section is shown in the following
table.
