■ Guideline for the setting
When you want to use the terminal [S4], set <F146: Terminal S4 input select> to "1: Pulse train
input". When you want to use the terminal [S5], set <F147: Terminal S5 input select> to "1: Pulse
train input".
Set the number of pulses per 1 Hz of output frequency at <F378; Pulse train input pulses number>.
The minimum number of pulses that can be input to the terminals [S4] and [S5] is 10 pps, and the
maximum number of pulses 30 kpps. The duty is 50 ±10%.
The maximum frequency that can be output is 200 Hz.
