Lenze EVS 9300 servo drive

I have a 3 axis robot. The servo motors and drives are from Lenze. It uses resolvers as a feedback. The servo modules are Lenze EVS-9322

I'm trying to figure out how to control this servo drive.

It appears to have the positional loop closed in the drive. The controller itself is an old i386 and it communicates to the drives via CAN bus with some sort of protocol?

On the servo drive the X4 connector is for CAN (gnd, Lo,Hi) and the X7 is for the resolver interface.
X5 is for drive enable and other signals like motor temperature, axis on limit switch etc.
X6 is for analog input +-10V

As I see it, I would need some sort of resolver card. 7i49? + 5i23. But what about commutation. If I remove the X7 resolver connector from the drive to use it in linuxcnc, will it turn the motor?

Any suggestions? via CAN protocol maybe?

Check if by any chance they have quadrature outputs, plenty of connectors there.
Even if they do not, no worries, Mesa has something for resolvers also, but i will leave that answer to PCW or Andy.
There are plenty of Mesa boards you cam use to controll them, usually i use one of 5i25 or 6i25 or 7i92 together with 7i77, works perfectly for incremental encoder feedback, but there might be other options more suitable for you.

@tommylight:Yes, I successfully used the combination of 6i25+7i77 with incremental encoders or glass scales and servo motors. Now this resolver thing is a new one to me

Regarding the quadrature output I do not seem to find it: (see attached photo)

Oh, nice!
It does have an encoder connector X8 but it is for feedback from motor as far as i can tell.
Have a look at mesanet.com, i am pretty sure they have something for that, too.

I looked up on this X4 connection(CAN) and it appears to use the CANopen protocol.

I read somewhere here on forums that it can be done, or it was etherCat?

Ethercat works nicely with linuxcnc, i am not aware of Can working although i do recall reading about it here regarding making that work,, so maybe someone already did something.
