(2) Analog Comparison Mode 1~7
Analog comparator mode 1~7, setting three parameters, analog input Ax, analog input Ay and reference value G.
Analog Comparator mode 1: (Ay- reference value G)≤Ax≤(Ay+ reference value G) , output ON;
Analog Comparator mode 2: Ax≤Ay, output ON;
Analog Comparator mode 3: Ax≥Ay, output ON;
Analog Comparator mode 4: reference value G≥Ax, output ON;
Analog Comparator mode 5: reference value G≤Ax, output ON;
Analog Comparator mode 6: reference value G＝Ax, output ON;
Analog Comparator mode 7: reference value G≠Ax, output ON;
Example for program and edit:
B003 (G01) output ON when the value of A01 in between (A05-2.50) ~ (A05+2.50);
Parameter display current value of Ax and Ay when running mode;
B003 (G01) output ON when the value of A01 is not greater than the value of A05;
Parameter display current value of Ax and Ay when running mode;
