EM1 and EM2 function in Mitsubishi servo

EM1 and EM2 are emergency stop functions in Mitsubishi JE servo.
EM1 uses dynamical brake, EM2 uses forced stop function.

Which one decelarates motor to a stop faster?

See the above information with diagrams on the IEC61800-5-2 Safety standard. EM2 is the faster stop.

Hello. I have related question. Which stop is safer for servo?
I need to stop servomotor in emergency situations (activation by photosensor) but I wonder how much it takes to brake servomotor after multiple emergency stops situtions.
