Stepper online A6 Servo motor as Spindle motor

I have a Stepperonline 1000W servo motor with an EtherCAT servo drive, which I intend to use as a temporary spindle motor until I can upgrade to a higher-power unit.
Currently, I have three axes configured to work with Leadshine servo drives via EtherCAT.How can I configure this servo motor to function as a spindle motor?
Specifically, what needs to be added or modified in the following configuration files:I’ve tried setting it up based on information from other forum posts, but I haven’t had much success so far.

What have you tried? Which Leadshine drive model?
I am going to propose to use PV mode. It is similar to a vfd.
You just give a speed and the driver ramps up and down as needed.
I have not tried it myself, and I don't have a driver to try it so it is up to you.
I foresee that the cia402 component needs modification, it only handles csp and csv.

I *could* put my stepper drivers in PV mode. So I am making a modification to the cia402 component to (hopefully) make a stepper motor work as a spindle (how useful). Servo drives also. 
Check back in few hours.
