I would recommend setting up Hal Scope to show the commanded position and the actual position (or perhaps following error or velocity error if there is a setting for that), then program some back and forth motion, increase acceleration until the following error grows at the point where direction is reversed. Then back off acceleration until the machine no longer has difficulty following the command. Simply put, accelerate as fast as the motor and drive are capable of, using Hal Scope to find that speed. If you do that and it seems excessive, you can always lower it.
