DC ripple voltage a problem?

Power supply gurus,
I am in the process of building a power supply and am calculating the
DC ripple voltage at full current draw. It appears to be around 4.7
volts with one capacitor value. I can get it down to 2.38 with
another of my capacitors. This power supply will be driving three
Gecko G201s running SloSyn motors at 57V @ 3-6amps.
My questions:
Will a high ripple voltage cause issues with the geckos?
Will the ripple voltage cause motor position stability problems?
I have read the Gecko white papers and although they explain how to
calculate the capacitor value, the don't go into any details about
ripple voltage and the issues that may result.
Thanks in advance for any info.
