How to put a 0-50Hz adjustable display on the HMI to be converted to a 0-10v to the drive?

Cribber

Hi guys,

I'm after some assistance, i am looking to do the same thing (controlling the speed of a motor on the the HMI). I have managed to tag the HMI to a network analogue input to my logo but am unsure on how to convert that figure to a 0-10v to the drive.

I am using function block diagram and have a network analogue input going to an analogue output but don't know what to put inbetween to convert it. I'm looking to put a 0-50Hz adjustable display on the HMI to be converted to a 0-10v to the drive.

Any help would be greatly appreciated

Many Thanks 

Use a mathematical instruction.
Using parameter VM mapping, write the value from the HMI into parameter V1 of the mathematical instruction. 

Hello Cribber,

you're welcome ...

Now I was wondering how to make it 0-50 and saw this topic. I tried it, but weird enough I receive the value of V1 when I go online after I VM mapped, but the drive doesn't receive a value. 

I added screenshots of how it did work and how I wanted to try it, but didn't.

The way it didn’t work.

Thank you, I hadn't activated the block. i negated it like you have and it works perfectly.

Sorry i'm new to programming so seem to miss the silly things.

Thanks once again

You make the same fault.

You don't have activated the mathematical instruction.

There are two options:
1.) Connect the EN-In put of the mathematical instruction with a HIGH block.
2.) Negate the EN-In put of the mathematical instruction. Place the cursor on the EN-Input and click right on the mouse. Then select "Invert connector".

Edit:

And please note:
The AQ needs 1000 units in his input.
If the value from the HMI is 500 (for 50,0 Hz), then is the multiplier 2.
If the value from the HMI is 50 (for 50 Hz), then is the multiplier 20.
