Hello, I have a small $450 frequency drive running a 1/4hp 3ph motor that I am not wanting to burn up. On this drive there is a 5k pot with 5 volts across it, that controls the frequency output/speed. I wanting to connect two more remote mounted pots to control the speed with a switch to select which one is in control. I was thinking of connecting the three pots in parallel with the center legs selectable via a sp3t switch. Is the actual resistance of the pots that important since all they are doing is acting as a voltage divider? Do I need three 15k pots to maintain the initial 5k load of the original pot, or can I simply add 2 more 10k pots that I happen to have handy. Any advice and thoughts would be greatly appreciated.
