RE: [CAD_CAM_EDM_DRO] Re: 1/2 winding current selection ?

These are 6 wire Vexta PK-268M-02A motors, 400 step per rev, 2 AMP, 2.25 Ohm
motors. I have tried running them using the full coil connections and they
do not perform well in my setup. I have now hooked them up using 1/2 coil
mode, center tap and 1 end connection, for each phase and they work fine.
My concern is that 2 AMPs may be more than the windings can stand in this
mode.
