Frequency Response Disturbance (% Max Current)

The disturbance magnitude for a servo-loop frequency response is measured by a percentage of the maximum peak current of the drive. Aerotech recommends that you start with a 5% Max Current. If you find one or more points that are not valid in the frequency response plot or if the response is very jagged, increase the % Max Current by 5%. Do not set the % Max Current above 20%.
