The E-Stop for a machine has 3 options, one is to disconnect ALL motive force driven items, the second is a controlled stop such as where the immediate removal of power will, or can, cause damage to personnel or machine.
I believe they are rated type 0,1 & 2.
This is where you would pick the correct version of the safety relay etc, that can give you a choice of options.
BTW it is customary to retain power to the central controller and all inputs, output power is usually terminated.
This allows some degree of trouble shooting, monitoring of PLC screen for e.g. etc.
