    Default New spindle, control question

    Greetings All! I have an older 4x8 PRT. I just pulled the 3.5hp porter cable router off and put on a 10hp spindle. It's a beast! The question is this. Does anyone know of documentation or guides illustrating how to wire up control for my spindle speed via VFD? I'm sure I can wire the shopbot controller to send commands to the vfd for on/off and speed control. I'm very technically fluent just need the schematics or any type of documentation. Thanks!

    Might want to specify what control box you have, what VFD, and the version of SB3 you're running.

    I have one of the USB spindle rpm controllers for sale if needed, it uses RS485 communication through SB3.
