read velocity from analog input

[rock0 0]

Hello!

I need help how is easy way to read real velocitiy from analog input with potentiometer.

I have CJ2M CPU and CJ1W-MAD42 analog module.

Best Regards!

Are you having trouble wiring the module?

Are you having trouble configuring the module?

Do you know how to scale the value in programming?

What are the units? (Hz, %, FPM, CFM...)

What is the range?

no I dont have any trouble with wiring,configuring and scaling.

I need read velocitiy in mm per second range is about 500mm stroke range

If you don't have any trouble, then what is your problem?

I'm glad you got it working. Did you use one of the Function Blocks for Analog Scaling from the Mr. PLC Downloads section?

I think his problem was to find velocity from displacement (analog input).
