6.6.5 Setting of frequency with the pulse train input
146 : Logic input / pulse train input selection (S2)
378 : Number of pulse train input
679 : Pulse train input filter
 Function
These parameters are used to set an output frequency by means of pulse train input signal of S2
terminal.

, This function is valid when the parameter fmod =11 (Pulse train input) and f146 =1 (Pulse train
input) are set.
, Number of pulses per 1Hz is set by parameter f378.
, Example of setting
f378 = 250 (pps) : Input signal = 250 (pps)  Output frequency = 1.0 (Hz)
Input signal = 1k (pps)
 Output frequency = 4.0 (Hz)
Input signal = 20k (pps)
 Output frequency = 80.0 (Hz)
f378 = 500 (pps) : Input signal = 500 (pps)  Output frequency = 1.0 (Hz)
Input signal = 1k (pps)
 Output frequency = 2.0 (Hz)
Input signal = 20k (pps)
 Output frequency = 40.0 (Hz)
Note) Minimum number of pulses to inputting S2 terminal is 10 pps, and Maximum is 20 kpps.
