There are none.

A true emergency stop kills all power to the printer. Since usually when you use one is to save someone or holy crap! it's on fire! situation. smiling smiley

You can hook up a normally-closed push button to a spare endstop input (e.g. E1) and use the M581 command to cause that button to execute an emergency stop if you wish. But as stephenrc says, one that cuts power to the machine is better.
