mind, I finally figured it out:
I needed to change only the Spice Model line, to make it unique to
the instance.
Then, the hidden control voltage must be that same unique name.

Sorry ¨C I forgot to click ¡°Notify users¡± in the upload:?
Vpct_pots.zip
Attempting to modify an archive Pot component, to add a wired Pin
instead of a hidden net name for control input.
In order to use more than one pot in a circuit, the SUBCKT
definition and instance parameters need to be modified for each
pot placed.
I¡¯d like to add a pin, and change the SUBCKT definition to use
that pin rather than a hidden net name.
I¡¯ve added a pin (4), removed the pin label ¡°Vpct¡± and used V(4)
to set the value of B1, but that¡¯s not working.
When Run, LTspice complains that the pin count of the instance
doesn¡¯t match the definition.
The uploaded zip has a working model, with the separate embedded
SUBBCKT definitions.
How can I make the mod, to add a control pin and have one
includable .cir ??
Still seems a lot of trouble to go to for each pot. I'm curious
what's wrong with Helmut's old (but excellent) pot library? That
uses a wiper position, which can either be a numeric (default 0.5),
or you can replace it with a parameter, which is unique to each pot.
