Re: Question for Mariss

The current is constrained by the G201 driver. I believe that the
higher voltage is used to get a shorter current ramp-up time in
order to get better performance out of the drive. Mariss, please
correct me if I'm wrong. From everything I've heard about the G201
drives I think they use magic to make them work and perform so well.
