Brother TC-211

Here is my plans for a RPC, they are pretty simple to build. I did find over the years that a motor designed for a RPC gave more balanced voltage between phases. I found North American Phase Converters to be very helpful and after many years of using old 3-phase motors I purchased a motor from them.

I saw your plans and they are very well written. Only thing is I am not good at schematics. I have a wiring diagram, showing the components, and hook up points on them all really dumbed down.

Ok machine is powered and running with the brother controller. Time to o the conversion. Thanks to pcw. I have the 7i77 card. Now I have a bunch of questions. I have a pic of the servo drivers. x,y and z are the same. Looks like the CN8 connectors are for all communication to the processor (I traced them back red white and blue wires). If I could get some advice on how to connect the drivers to the 7i77 card I would be appericative. The text pics are from my manual and describe the input/outputs. I'm just totally lost. Electronics are not my strong suit. So any help in appericated. especially PCW if you could chime in.

Ahhhhhhhh if someone can fix up the picture posts for me, and sorry they are upside down

Thanks andy

Someday I'll figure it out

A sharper version of the third drawing would help a lot
(so pinouts can be read)

Looks pretty standard and simple other than the torque limit option

Here is the redo of page 3 It is at a much higher res.



and page 2 redo hi res

Here are representative connection guesses for X (channel 0)


I am making some assumptions here,
first assumption is that the start pin of the drive is not latched (its a drive enable)

The second assumption is that the current limit mode is not needed

Well got back from the cable store. 115 for cabels, so this weekend its time to get the machine under linux control. Hope some of you are here for tech advice as needed.

Eek! But then the connectors for my servos cost 2x what I paid for the three servos, so not such a surprise.
