What is the scaling of PID feedback value when the feedback is taken from pulse input on LI5?

The scaling between feedback value (RPF parameter) and the pulse input when assigned as PID feedback (PIF=RP) dependss on following parameters:
- min PID feedback setting (PIF1)
- max PID feedback setting (PIF2)
- min pulse input frequency (PIL)
- max pulse input frequency (PFR)
The conversion between pulse input value and PID feedback is linear and PIL corresponds to PIF1 and PFR corresponds to PIF2.

For example, PIL=5kHz, PFR=20kHz, PIF1=0, PIF2=10000
Then
- at input frequency below 5kHz, the RPF=0
- at input frequency 10kHz, the RPF=3333
- at input frequency 15kHz, the RPF=6666
- at input frequency 20kHz, the RPF=10000
