I plan to use mach4 and gecko to drive my Allen Bradley servo drive and motor. I just need to know if there is any lack of accuracy when you boost the speed the step pulse frequency of the gecko. My motors can turn at something like 3000RPM with 1500lines encoder, so I don't know if a gecko will be able to drive them a full speed with precision. Can anyone help me before I spend 400$ ? And if I m totaly wrong, can any one explain me ( the fact that there are 32767 differents speed, I loose something here...)?
