Looks like all the connections are there for 4th axis, should be a very simple plug and play proposition.
Those are Bosch servo drives, for which replacements and repairs are available. The Siemens servo motors are the "good" ones, and by all accounts are pretty much bulletproof.
Interesting to see the Siemens module, it's much bigger than anything Dialog4 related in either of my machines- which have that hardware on the other side of the cabinet. The Siemens 3M connection is kind of interesting too, as they eventually bought out Grundig, who produced Dialog.
