Hello All,
This is my first time working with encoders and I am a little lost. I have a 1769-HSC/B card on a Compactlogix L32E controller running RSL5000 v20.13. I have a Sick encoder with a PPR of 16,384. My count does not seem to be accurate in the program. I tried to rotate the encoder approximately 1 revolution by hand and have come up with very different counts (it varies by 1000+ pulses in some cases). So I guess one question I have is, if the counter is set for Encoder X1 should my count be 16,384 or 1/4 of that 4,096? Because it's definitely closer to 4,096.
Additionally, I have to rotate the encoder very slowly to even get it to count. In it's actual application I will need the encoder to rotate faster than what I am doing by hand.
I assume since my pulse count is high I need to configure my counter differently to be able count accurately but I am not sure how to do that. I read in the manual about the cyclic rate calculation but I am confused about how I figure out my update time. Am I headed in the right direction?
I would appreciate any help.
Thanks
