Drives require you to "tell" them the source of the start signal....keypad or terminal etc...
Next it requires you to set the frequency ref point...either the keypad/on board pot or external 4-20mA or external 0-10V.
These analog speed ref inputs are also able to be scaled by parameters, giving you flexibility...
I will check the speed ref parameters required for your application. Meantime you should connect the 12 or 24 V power to your bob...
Give me a little time....just going out for a couple of hours, then i will help you
Will also show you how to set up your drive to see the analog value for testing purposes....
