Adjust the setting frequency by multi-speed function
Multi-speed function offers flexible, switchable 16 independent stages of setting
frequency. The rotation direction of each stage depends on both the 'Stage ac-
tion' and the 'Run command source', see the table below:

Tab. 12-2: Setting frequency and multi-speed settings
To configure the multi-speed settings, take the following steps:
Step 1: Activate multi-speed function

Step 2: Select any 3 digital inputs and define functions accordingly
Assign functions to digital inputs properly when 'Acceleration / deceleration
time activation' and '2-wire / 3-wire control mode' are also necessary defined via
digital inputs.

Step 3: Configure the setting frequency for each stage
If the setting frequency of next stage is lower than that of the current stage, it
will decelerate to the next stage with the deceleration time of the current stage;
if the setting frequency of next stage is higher than that of the current stage, it
will accelerate to the next stage with the acceleration time of next stage.
