11.3.1 Safe Inputs
The Safety Module has 6 parameterizable inputs on two channels, which can be assigned
with the safety functions, which are described in chapter
Z
Safety Functions
–
from page
55. The safe inputs of both axis can be used for this axis, if only one axis is operated.
The parameterization of the safe inputs is made with the parameterization tool
ProSafePara.

Logic isolation.
m
For the operation of sensors with OSSD-outputs according to EN 61496.

OSSD-outputs possess test pulses. This way the inputs of the Safety Modules can be
parameterized in such a way, that they are not enabled by these pulses.
Crossfault detection / Short-circuit detection
m
For the detection of external input-sided short-circuits between two inputs and for the
detection of short-circuits of the inputs against electrical power supplies, external clock
signals are supplied with current via the cycle outputs of the Safety Module when using
electro-mechanical safety switches (e.g. emergency stop) (see chapter
Z
Cycle
Outputs

from page 97).
m
Detection of internal errors of the parts and of internal crossfaults due to diagnostics
functions.
NOTE!
The inputs comply with the specification type 3 according to EN 61131-2.

11.3.2 STO-Inputs
The Safety Module has 2 STO-inputs on two channels for the activation of the safe pulse
inhibit.
When activating the safe pulse inhibit the generation of a rotating field for the motor
control is interrupted. With this the drive is put into the status STO (Safe Torque Off). The
energy supply to the motor is not affected by this switch-off operation.
