Existing AXOR - MiniSpeed 200 Drives spec

Tachogenerator feedback ✔
Armature feedback ✔
Torque mode feedback ✔
SMT technology ✔
IGBT or POWER MOSFET bridge ✔
✔ Encoder feedback
✔ PWM + Dir. feedback

So the drives are PWM and not step and direct... there is literally nothing I can find on the encoders...

Due to my lack of CNC and machine code experience...Do you think I should really be looking at a full swap out i.e Controller/drives/motors?
