Hi guys,
How do you calculate the right ppr for max. shaft speed of 3,100 rpm. I am using a photoelectric switch to detect number of pulses per revolution. I know I have to look at the response time of the switch as well as the max. speed 3100rpm.
Is this right so far? 3100rpm = 51.67 rps
max. ppr or default ppr of motor controller = 1024 ppr
max. frequency = 51.67*1024 = 52910.08 Hz
Now I am lost. If I choose 8 ppr (because for my application's current ppr is 6) 51.67 rps * 8ppr = 413.36 Hz which is below the encoder speed feedback of the motor controller. I am not sure if this is right but any pointers in the right direction welcome! Thanks!
