Posted 4 Feb 2021 Hello everyone and thank you for this forum. I am new to omron programming. My project is to find out how fast my gear turns. I had a 12 inch diameter gear cut with 96 teeth on a laser. I put a proximity switch to give me the number of impulses that I have returned. my gear turns between 1 foot minute to 15 foot minute. I test everything on a CP1L-L10 and then I'll put it on a CJ2M because I can't stop the machine or I have to put my project. this is to confirm that I am driving well at the requested speed. I have tested block 881 and block 883 and I cannot be precise enough in my data. I arrive at 1 min of precision and I must arrive at 0.1 of precision. I don't know if these clear enough. thank you for helping me. My native language is French. so sorry if there are any mistakes. Share this post Link to post Share on other sites
