I need to be able to read the RPM of an encoder. I am using a 4096 step per revolution encoder with a UMI-7764 connected to a PCI-7344. Looking to measure speeds up to 500 RPM. I have seen a few other places where people have asked to do this but have found other solutions. Due to a large installed base of multiple systems (around 40), I cant change the the hardware configuration.
Specifics:
Encoder 4096 counts per revolution wired to encoder input (A,A-,B,B-)
Max speed 500 RPM
NI Motion card PCI-7344 /w UMI-7764
LV 8.5 and 10
I made a few attempts to measure number of counts in a unit of time but nothing remotely accurate or stable resulted.
Thank you
Any help is greatly appreciated.
