Kinetix 300 Drive Safe
Torque-off Wiring Diagrams This appendix provides typical wiring diagrams for the Kinetix 300 drive safe
torque-off feature with other Allen-Bradley safety products.
For additional information regarding Allen-Bradley safety products, including
safety relays, light curtain, and gate interlock applications, see the Safety Products
Catalog, website

The drive is shown in a single-axis relay configuration for both category 0 and
category 1 stops per EN-60204-1 Safety of Machinery Directive. These are
examples, however, and user applications can differ based on the required overall
machine performance level requirements.

IMPORTANT The Kinetix 300 drive has been qualified and rated as a component to meet ISO
13849-1 performance level d (PLd), safety-level category 3. Dual inputs and
drive monitoring of the safe torque-off circuit, STO-4 and ST0-6, are done to
prevent drive enable should either or both of these inputs not function.
It is suggested to evaluate the entire machine performance level required with
a risk assessment and circuit analysis. Contact your local distributor or Rockwell
Automation Sales for more information.
