I"ll try that..  One other question. The motor connections on the drive are labled R,S,T, . Is it important how these connect to the motor?

I had to change the file extension to .txt so the forum would allow me to upload it.

Here it is.  Hope it makes more sense to you then me.

got into the DSAPro communtation Diagnostics.

I run a test at 10%,  The motor moves but somewhat erraticly and the software recomends wiring changes "V conection move to W,  W connection move to V"

I have no idea what a V or a W connection is?

Its the terminals your motor connects to on the drive, U V W or can also be R S T.
It varies from drive to drive in the model  range, so if your drive has R S T then you need to swap the wire thats on S and put it on T and the one thats on T put on S, make sure the drives powered down fist though ;D

OK, no more errors there after making that change.  It's telling me to set the hall to 300 degrees?

OK, all, Hood in Scotland was invaluable in got me pointed in the right direction.  I've got G&L drives working and motors tuned, interfaced with Mach!

Good stuff, great camaraderie, This site rocks!

Hope I can return the favor and help the next person move forward!

Best, Tristar500

Great to hear :)
If you are  wanting the details of the line driver for the board I made up for myself give me a shout again on skype and I will send the pdf over.

Hey Hood, still working out the details of the final shape of the machine frame.

If you like you could post the line driver PDF here?

Wiring up the motors to the drives are fairly straightforward, the drives can accept single ended outputs for Step/Dir but I prefer to use the Differential inputs. As the signals from Mach are single ended you need to make up a small circuit and use a line driver to turn them into differential outputs but as said its not needed but preferred to help with noise immunity.

can you help me with the circuit to turn single end outputs to differential outputs? I have a servo drive that only accept differential signal and I want to use mach3, thanks in advance, JB
