I guess I dont get what those drive outputs connect to, because for my X axis I have A+, A-, B+, B-, C+ and C- pins.  Those are noted as running in P and S modes, whatever that means...

I see where the CSMIO output goes now, the CSMIO has an X+/-10v and X ground pins, which connect to pins 12 and 13 on my driver, those are analog input +/-10v and analog input ground.

Will all of these pins be used (ex. alarms and servo enable, etc...)?  Do the rest of them go to the Digital input pins on the CSMIO? All of my other projects have been with stepers and simple breakout boards so I'm sorry for asking what may be some really silly questions....

I get the Encoder Feedback ABZ+/- on the driver go to encoder feedback ABI+/- on the CSMIO. But loking as CSMIO vs the driver I see Coder Aout, Bout, Zout+/- on the driver but see Analog output XYZABC +/-10v and XYZABC ground on the CSMIO, thats 6 pins on the driver per axis, but only 2 on CSMIO.  What am I missing there?

On the next page it has details about each pin. Some have a P or S mode which is for 'Position' or 'analog Speed.'

There is a note about some commands being for position control mode vs analog speed control mode. Are those to differntiate between digital and analog control, so I will not use the position mode I/O?

The I/O under the CN2 label (left side) are all supposed to connect to the CSMIO anyways so that works, I just have to put those into the encoder A B and I +/- inputs?

My axis motors arrived earlier this week.  As we just discussed, the positioning loop goes CSMIO->Driver->Motor/Encoder->CSMIO, my motors have all of the cables and plugs to connect the motor/encoder back to the driver, now I assume I could just lop off the connector and plug the wires into the CSMIO, but there are A LOT of wires, do all of these return to the CSMIO?

My spindle is belt driven, but I am not sure that there is actually any gear reduction, I will have to check.  Would it be better/would it matter where the integrated encoder feedback goes, vs the second encoder?  I should be able to buy whatever kind of encoder I need off of McMaster-Carr or some industrial supply store right?

Right, I meant that since the driver itself can make the loop it should be able to do the same vi the ENC module.

I did talk to CS-Labs about what I need though and they gave me a diagram for AC induction vs AC servo spindle control that showed encoder feedback going to both the ENC and the driver, I thought (like you just mentioned) that the feedback just goes to the ENC module, but according to this the loop goes to both?  Or does one control speed and the other is position?

In any case those motors should do the job right?  The 3.7kw specs are right on with my existing motor, and bumping up to the 5.5kW isn't much more money, so maybe I could turn this from a drill and tap machine to a more capable mill.

I'm waiting to hear back about the 230v Allen Bradley motors, but if it comes to the point of buying a new spindle servo I think that the GSK ZJY208 3.7 or 5.5 motors will probably be the route I take. They take analog signals, and have tge speed and power I need, and since they have closed loop control I know they should work with the CSMIO ENC module.
