When switching between the master and auxiliary speeds, set H3-05 (Multi-function analog input terminal
A3) to 2 (auxiliary frequency reference, 2nd step analog) and set on of the multi-function input terminals to
multi-step speed reference 1.
When inputting a current to terminal A2 for the master speed frequency reference, set H3-08 (Multi-function
analog input terminal A2 signal level selection) to 2 (current input), and set H3-09 (Multi-function analog
input terminal A2 function selection) to 0 (add to terminal A1).

Setting Frequency Reference Using Pulse Train Signals
When b1-01 is set to 4, the pulse train input to control circuit terminal RP is used as the frequency reference.
Set H6-01 (Pulse Train Input Function Selection) to 0 (frequency reference), and then set the 100% reference
pulse frequency to H6-02 (Pulse Train Input Scaling).
