1.2.4 Safe inputs
1.2.4.1 General
The following applies to the sensors at the SM301 V1.0:
ƒ Sensor type and sensor function can be parameterised in C15030, C15031 and
C15032.
ƒ A local evaluation is executed if corresponding parameters are set.
ƒ If a safety bus is activated, the sensor signals are sent as status information to the
higher−level control.
ƒ Deactivated sensor inputs must not be connected. The status of a non−connected
input is in the OFF state.
ƒ If a signal is detected at deactivated sensor inputs during initialisation, the drive
remains inhibited (STO).
ƒ Faulty inputs are assessed as OFF state.
Additional conditions for SM301 V1.1:
ƒ With active cascading in C15035 the SD−In4 input cannot be used freely anymore.
