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.
[Parameter setting]
Title
Logic input / pulse train input selection
f146
(S2)
f378 Number of pulse train input
f679 Pulse train input filter
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)
f378 = 500 (pps) : Input signal = 500 (pps)
Note) Minimum number of pulses to inputting S2 terminal is 10 pps, and Maximum is 20 kpps.
Function
0: Logic input
1: Pulse train input
100-5000 (pps)
2-1000 (ms)
Input signal = 1k (pps)
Input signal = 20k (pps)
Input signal = 1k (pps)
Input signal = 20k (pps)
F-21
Adjustment range
 Output frequency = 1.0 (Hz)
 Output frequency = 4.0 (Hz)
 Output frequency = 80.0 (Hz)
 Output frequency = 1.0 (Hz)
 Output frequency = 2.0 (Hz)
 Output frequency = 40.0 (Hz)
