6.10.5 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 output frequency by means of pulse train input signal of S2
terminal.
[Parameter setting]
Title Function Adjustment range Default setting
f146
Logic input / pulse train input selection
(S2) 0: Logic input
1: Pulse train input
0
f378  Number of pulse train input 10-500 (pps) 25
f679  Pulse train input filter
2-1000 (ms) 2
,
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 = 25 (pps) : Input signal = 25 (pps)

Output frequency = 1.0 (Hz)
Input signal = 100 (pps)

Output frequency = 4.0 (Hz)
Input signal = 2k (pps)

Output frequency = 80.0 (Hz)
f378
= 50 (pps) : Input signal = 50 (pps)

Output frequency = 1.0 (Hz)
Input signal = 100 (pps)

Output frequency = 2.0 (Hz)
Input signal = 2k (pps)

Output frequency = 40.0 (Hz)
Note) Minimum number of pulses to inputting S2 terminal is 10 pps, and Maximum is 2 kpps.
