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