Kollmorgen VFS5 Series Spindle Drives

Kollmorgen VFS5-240-00-2031E

Overview

Spindle drive VFD with resolver/encoder feedback, meant for CNC applications where spindle orientation and speed regulation are important. It seems that it might be be a modified version of the BDS5 servo drive (the documentation would indicate they are very similar).
