the siemens 611 drives are generally very reliable, i would fix the power supply and be back in operation.

amp 305183-r works on all the cpc connectors i have ever worked on

on a fanuc a06b-6055-h112 drive i have
cn1-14 to cn1-45 close to enable spindle cw
cn1-14 to cn1-46 close to enable spindle ccw
cn1-47 to cn1-48 n.o. e stop contact
cn1-19 to cn1-20 is a n.o. alarm reset

price, location?

there is probably still a parameter set wrong somewhere. are you using encoder feedback?

you could maybe steal the encoder signals off the z axis or add a dedicated encoder to drive a third party servo drive used in a follower type mode, i.e. the pulse train from the encoder would drive the servo drive to mimic the z axis.

attached is an example of rc snubbers on motors

you should also use 3 phase r/c snubbers from phase to phase on all motor contactors

i think you are out of luck, you need a servo system to do that not a vfd
