MELSEC-F Series Penghitungan Kecepatan Tinggi

Dengan menggunakan penghitung kecepatan tinggi, sinyal kecepatan tinggi dari encoder dan sensor dapat dihitung.
Karena FX PLC memiliki penghitung kecepatan tinggi yang terintegrasi, kontrol kecepatan tinggi dapat dilakukan dengan program sederhana. Blok penghitung kecepatan tinggi dengan pembanding perangkat keras juga tersedia.
