Basics;

Does a 10k pot between VR, VI, and ACM control the spindle speed?

Does a switch wired between FOR and DCM, start the spindle?

PD001 and PD002, need to be set to "1" external terminal.
If you have PD001 and 002 set to "2", then it will expect RS485 communication.

I don't see a "V10", it should be "VI".
