Example of the connection of option K82 with a separate CU320 for several Motor Modules
In this example, Motor Modules without their own separate CU320 are operated on the same safety switch shown in
the previous diagram. They are driven by a central Control Unit which is also responsible for controlling the selected
safety function. The interfaces are the same as in the previous diagram. The only difference is that signals must be
taken to the externally mounted CU320.
Option K82 allows optimized hardware interfacing between the SINAMICS and the existing plant. Please note that it
is essential to activate this firmware function during commissioning.
In combination with option K82, the requirements according to the machinery directive 98/37/EC and EN 60204-1 are
fulfilled as well as the requirements according to DIN EN ISO 13849-1 (formerly the EN954-1) category 3 and
Performance level d plus safety integrity level (SIL) 2 according to IEC 61508. The integrated firmware saftety
functions are already certified and the certification of option K82 is in preparation.
Please note the additional information on the safety functions Safe Torque Off and Safe Stop 1 in the chapter
"General Engineering Information for SINAMICS" in the section "Safety-integrated, drive-integrated safety functions".
