Re: current limiting power supply for stepper?

Hi Grant,

there is a maximum current you can pump into a motor. voltage is
limited(chopped) to keep the power on the upper end of the curve.
current monitoring is how it is done.

for reasons why 25 times nameplate is the max as far as voltage goes,
read the white paper at www.geckodrives.com
