Engineering Information
Example 2:
The second example shows a system with S120 Cabinet Modules equipped with Motor Modules in Chassis format
and illustrates how a central safety switch can be used to switch all the Motor Modules within one safety group. The
terminal design and / or terminal arrangement is such that only one multicore cable is required to connect the
individual Cabinet Modules.
All connections between the Control Unit, power unit (CIM module), customer terminal block -X55 and option K82 are
pre-wired inside each S120 Cabinet Module, i.e. the cabinet is shipped in a ready-to-connect state.
The SIMATIC S7 drive control is not required to implement safety functions STO and SS1 and is included by way of
example only.
Wiring of option K82 on S120 Cabinet Modules with one CU320-2 per Motor Module and central safety switch
Example 3:
The third example shows a system with S120 Cabinet Modules equipped with Motor Modules in Chassis format and
illustrates how multiple Motor Modules can be controlled by one single Control Unit and operated by means of a
common safety switch.
The same interfaces are used as in the previous example. The only further requirement is to route the signals to the
common Control Unit.
The SIMATIC S7 drive control is not required to implement safety functions STO and SS1 and is included by way of
example only.
