You need to reduce the acceleration settings in the ini file, and increase the following error limits. Then, you need to plot the follwing error using halscope while you gradually increase the commanded velocity and acceleration. When you see the following error in halscope show significantly, then you need to adjust the P, I and D parameters using the settings/calibration menu in the TkEmc GUI or machine/calibration in the Axis GUI. By proper adjustment of these settings, you should be able to reduce the error at some specific speed/acceleration. You can keep working up in speed and velocity and improving accuracy until you reach the performance you desire, or the limits of the servo drive.
