I'm wiring up a VFD for my son - he's WAY more lectrically challenged than myself.
I've used a 0 - 2K ohm pot many times for speed control and bought one for this job. The manual on this unit has very little info about using a pot. On chapter 2 page 11 in the lower left corner it seems to call for 3 - 5 K ohm pot
later on in the programming section it implies using a pot to get 0 -
10 volt for speed control and using a pot is acceptable. The volt source on the unit is 10 volt. To my thinking 3K to 5K resistance won't give 0 - 10 volt from a 10 volt source.Read Chapter 4 starting at page 32
I just asked the kid to buy me a 3K ohm resistor and mail it to me to put in series with the 0-2 Kohm pot. But this just seems wrong to me.
Can somebody explain?
