I can't state any differeces from actual experiences. But, note that
the Rutex
drives have a tolerance of either 20,000 or 30,000 encoder counts, depending
on model. That means that the axis can be up to 20 or 30,000 counts away
from the commanded position before the drive sends a fault signal to the
computer! What will that do to your workpiece? The Gecko 320 and 340
drives can be no more than 128 encoder counts away from the commanded
position before signalling a fault condition. That may still be excessive
in some situations, however.

The only advantage of the Rutex is that it allows higher voltages, which may
be beneficial with specific (higher voltage) servo motors. I guess they
also
have a 40 A drive, now. But, I wouldn't consider them unless I had encoder
feedback direcxtly to the computer for the above reason.
