Hi Neil, Setup a failsafe circuit with the connection passing through the E-stop contacts energizing a relay. If anything in the series circuit becomes open (E-stop button, relay contacts in E-stop circuit, overtravel limit switch contacts, etc.) the functions dependant upon that circuit being closed stop functioning.
Someone may have a schematic example to share. If not, email me and I will send you an example.
