Hello,
I'm new to analog signals as far as scaling them and what the useable output voltage will be. I need to utilize the 0-10vdc output. I have a value from n11:0 that ranges in integers from 0 -60. I would like 0-60 to represent 0-60hz on the vfd Im trying to control. I understand how to use the scp instruction somewhat but I want the scale to be for instance:
n:11 = 45 so output voltage to 7.5 vdc
Im totally missing something. Why doesnt the analog output address like decimals so I can get finer control instead of increasing the integer value without any output movement?
If you couldn't tell I really need the help.
Dave
