Jovel Posted May 17, 2023 Report Posted May 17, 2023 Hi Guys, I may need some help on how to program the stepper motors by using FX5UJ PLC. This is my first time using it, not too familiar with Mitsubishi PLC. Anyone can share me sample program for reference? I have no clue what command needs to use. I only have experience in Omron Sysmac Studio programming servo using Ethercat. Other than that I can say I'm a new guy in PLC. Thank you very much for helping me.
FRANK RUIZ Posted May 17, 2023 Report Posted May 17, 2023 never did it myself, but I found this quite useful. https://plc247.com/fx5u-step-motor-control-tutorial/ hope that helps.

Jovel Posted May 17, 2023 Author Report Posted May 17, 2023 Does anyone know why the output is ON without triggering ? Or do I have some parameters that haven't key in? Thank you
Goghie Posted May 17, 2023 Report Posted May 17, 2023 It is generally called AlwaysOn. Documentation for FX5 is excellent and quite big, I suggest you to read it. 1

Why I haven't trigger the Servo.iPosLimit, the Output is ON ? Thank you
glavanov Posted May 18, 2023 Report Posted May 18, 2023 ServoiPosLimit, ServoiRevLimit... Did you make these labels? Local or Global? What are their settings?

glavanov Posted May 18, 2023 Report Posted May 18, 2023 (edited) Somthing is wrong. Тry to replace the labels with the actual Xn inputs where the limit wsitches are connected. Depending on whether the limit switches are NO or NC type, you will put a normally open or normally closed contact in the ladder. Edited May 18, 2023 by glavanov
