Seeking help with LTspice simulation of Variable Power Supply
ChanceMcCrance:
Hello,
I am trying to create an LTspice (version XVII) simulation of a variable power supply. When I try to run the simulation, I get an error saying "Unknown subcircuit called in: xr1 n004 n003 5000." Based on what I have read, the software cannot find the subcircuit for R1 (5k, variable resistor). The component was taken directly from the LTspice library, so I was not sure why I encountered this error. Any insight as to how I can correct the issue? Is there something I should add to the simulation command?
Any help would be super appreciated. The file is attached if you would like to test it for yourself.
Best,
Chance

Why don't you try this one instead? ;)
Ian.M:
The description of 'xvaristor.asy' that you used for R1 says:
--- Quote ---Generic varistor symbol for use with a model that you supply.
--- End quote ---
If you simply want to patch it to run with the default fixed resistor model, Ctrl-click R1 to open the component attribute editor and change the prefix line from X to R
mdszy:
Is there a specific reason you need a variable resistor model? You can always do a .step command to change the value of a normal resistor across multiple simulations and see what the effect of changing the value is.

I wanted to create a simulation of a variable power supply that I had built which used a 5k variable resistor. I suppose using the .step command would be ok for now.
