hi, im using cj1m cpu22 and I plan to use the built in high speed counter to count the pulses from a rotary encoder. We are measuring the rpm of a screw which will either speed up or slow down. I know that the high speed counter will be able to read real fast pulses but will it be able to read slow pulses as well? I asked this question because someone from our engineering dept told me that theyve already tested that and high speed counters are not accurate when it comes to reading slow pulses, is that true?? if so, any alternatives i can use? thanks.
