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 http://www.ab.com/catalogs
.
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.
Figure 79 - Single-axis Relay Configuration (Stop Category 0) with Automatic Reset
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.
