By activation of the emergency stop unit, e.g. by protection door, the release circuits of the
safety module are opened. 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).
