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 3) and
thus to energy disconnection of the drive. The safety module makes a consistency check of
all signal paths via test signals (OSSD).
