Hi all,
I am trying to get clarification on my calculations because they don't feel correct. I want to calculate how fast my encoder is pulsing.
For the info. I know my encoders resolutions 200 pulses per revolution and that my wheels circumference is exactly 1 foot.
I also know that the average speed is about 115 rpm. or 1.9rps. (lets round it up to 2 for sake of ease)
Here's my work:
2 rps * 200ppr =400 pulses per second. I then invert this to get how many seconds between readings. 1/400 = 0.0025 = 2.5ms/pulse.
So according to this I pulse every 2.5ms which will be sent to a PLC to be read. I believe this is fine?
I think ive just been staring at this too long! Thanks!
