If there is a ‘max’ speed for each of the axes you can set.
There is also acceleration values you might want to reduce on the rotary axis.
Access them ‘Edit → Machine Settings’.
While you are there, ‘save’ the current setting, before you change them. You have to ‘write’ new settings to the controller after you modify them.
When the rotary is setup, again ‘save’ the current settings under another name. You can ‘load’ the settings and ‘write’ them to the controller.
Good luck
