With operation of the emergency stop unit, e.g. by protection door, the release paths of the
safetymodulearedisconnected.ThisleadstothelossoftheSTOsignals(X2B.1and5)and
thus to energy disconnection of the drive. The safety module makes a consistency check of
allsignalpathsviatestsignals(OSSD).
