I am a new owner of an R7 kit with the Pro controller. For awhile now I have struggled with minor problems that kept me from completing the build, but now it is almost finished. Almost.
(Personally I have found that Hobby-Fab customer support is truly exceptional, but both the written and video instruction is a bit lacking.)
Per the instructions I connected the three wires from the spindle to the terminal block on the x gantry plate. Now what? I have an “accessories” connector to the controller that needs to be connected to four points (p. 45):
Yellow/Blue= (+/-) PWM
There is also a pair to connect to a probe, but I don’t have one of those so not worrying about them for now.
I have this from the website:
Wiring to the spindle is simple
which I assume means that the VFD outputs of U, V and W should connect to the three wires at the terminal block such that the letters match to the pin numbers inside the spindle connector.
The above would indicate, then, that those connections to the controller are from the VFD. But where, what, how?
So I watched the “OX and R7 wiring example video” once more. OK, I think I connect the Red and Green wires to A1 and N1 (or vice versa). Also I have to jump something, maybe X1 to X3, but not sure since it was left up in the air in the video. Now all I need to know is where to connect those pesky yellow and blue wires.
In that video it is stated that what is being presented is “in the manual”. If that is true I don’t have the manual.
I did download the VFD instruction book but attempting to get anything from that turned my mind to mush pretty fast.
Can anyone here give me some help? Please keep it as simple as possible; I’m a woodworker with a 55 year old aero engineering degree so anything beyond plain electrical connections gets confusing fast.
