FX3U PLC Encoder Output Pulses

2 posts in this topic

Hi All, I m new in this platform I wanted to know that I have FX3U 16M PLC which is connected with encoder X0 & X1 input and the program is simple it output the pulses and give it to the servo amplifier so the servo motor runs according to the pulses generated. But the problem which I am facing from few days  is that servo motors runs perfectly fine but the tape which is running on the servo belt is not cut in exact position however before that it works fine and cut the tape in exact position. So my question is that how many output servo needs for that maybe some wire from plc output is broken ?

Currently in program there are 3 outputs given at the PLC side pulses output Y0 & Y1  and Y2 is digital output but physically there are 2 outputs connected with servo Y1 & Y2 so I  need to know is there is any output for positioning ??
