| 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 |

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. |
