Shaft Encoder Calculate RPM

[Haver]

Hey.

I have my Shaft Encoder connected to HSC 0 , But i cant get any value from my Frequence measurment from my HSC. In Net 2 MI44 always show value 16 ? cant find out why?

Is this the right way to get a Speed measurment from my HSC  input?

I have 24 bolt pr. round. 

I dont need to be wery accurate, only an close estimate of the speed ,

My programs counts Meter + and  - , in the display.  but i cant get a RPM to run at the same time.

Do i need a new Sensor to only count the RPM ?

I try to post some solution from my project

Please try to do something like that:

ML5 is used for FREQ

SPEED calc from ML5 FREQ MESURE

MF1 calculation:

You must do some math ..... FREQ to RPM....

in my project example i need to calc m/min from ML5 FREQ

Hi, Thank you,  I will test this today

To what and where do you set your MF1 1IMP ?  Is this how many Impulses you get in one turn?

And why do you mult f MF9 / with 240 ?

[kratmel]

MF1 - mm/imp  - how many mm will go raw material when encoder weel run  = 1 imp

See  image  MF1 calculation: rung4

 

240 = 4*60sec

4 = 4x encoder mode
