If going the CSMIO route you will have the CSMIO/IP-A itself and I would recommend also the MPG module, not the pendant, just the module, unless you wish to have the pendant of course
. You may require an extra I/O module as well depending on the amount you will require.
The only real advice I can give is study what you have, try and work out what connections you will need and that will help you decide.
The analogue output controllers for Mach can use any analogue controlled amplifiers, in other words if your amplifier/drive gets its command from a +/- 10v signal they will work with these controllers.
All of these controllers will also require that you can feed the encoders back to them so either the encoders on the motor need to be 5v ttl signals or that any simulated/pass through signals from your drive are that.
To explain the last poart I will give an example. Some of my machines use Sine/Cosine encoders on the motors, these are not suitable for the controller. These signals however are read by the servo drive for its own use and then the servo drive will condition these signals and pass them out as square wave signals which are suitable for the controller to use.
Sorry its not a huge amount of help but without knowing the specifics involved its impossible to say what is required.
