Servo seems to ignore FS and RS limit when set at high speed

Servo seems to ignore FS and RS limit when set at high speed

I have been working on a program that, when finished, will need to use a relatively high speed. I have been testing my program at slow speed, but now that I am nearly complete and using a high speed, the servo is surpassing its limits and grinding against its physical constraints. Is there anything I could be doing that would cause this? I've tested this by switching speeds between tests and can confirm that the only difference between tests is the speed and acceleration. Thanks
