Dan,
bit rushed at the moment so will answer a few of your questions and if I make it to the workshop today I will have a look regarding the FRO to see if I get the same issue regarding the fast wind.
I found that the MPG module was slightly less responsive than direct connection to the main module for FRO etc however I also found that a log pot gave much better response. BTW what resistance pot are you using? Also if I recall the Analogue on the MPG module is 5v rather than the 10v of the main unit, just in case you are using 10v. I think the manual says analogue 0-10v but unless its been changed that is wrong. You take the feed for your pot from the 5v output.
Regarding the outputs, if I recall they are sourcing only, so you have your power and 0v to provide power for it and the actual output will output the voltage. I dont think you can use them as sinking outputs, I am sure I had to make up wee relays for the Fara drive I have on the wee lathe as its inputs were sourcing.
E-stop, the connections on the main power plug (E-Stop1 &2) I think are meant for connecting an E-Stop string into the MPG module, for example you may have an E-Stop fitted to your panel, if you wished you could connect that into the string to halt the Mach if the E-Stop on the MPG is pushed.To do that the 24v is already going into your E-Stop switch and you then feed the other side of your NC into EStop 1, you then take a wire from EStop2 and put that to 0V (or feed it back in to the external E-stop string to continue it.
So what EStop 1 and 2 are for is to halt the rest of the E-Stop string, I think basically they are acting like a relay, if you halt the MPG modules E-Stop then these contacts will open and thus your main E-Stop string will be open., hope I have not confused the situation as I know what I mean but may not be putting it down in words very well
Regarding the actual E-Stop on your hand held pendant, I think you would use pins 13 and 25 and have a NC contact on the E-Stop button.
