Make shure the 2nd MM4 has shorter ramp times then the 1st one. So the 2nd MM4 will follow the speed of the first one. This may work if you have a mechanical reversing of the traverse. Normaly there is a PLC, or similar, to calculate the speed of the traverse.So Ithink you can't solve your problem so easyly.

It's a life and death problem ! If this is really a "life and death problem", I would certainly try to READ THE USER MANUAL!!! I'm sure, there is a good description, how to do it. (Parameters 770 to 785; Function diagram 2300...) Have fun!
