Preface
About This Publication This manual provides detailed installation instructions for wiring and
troubleshooting your Kinetix 6000 and Kinetix 7000 safe torque-off drives.
Included are interconnect diagrams with Allen-Bradley safety relays, GuardLogix
controllers, and GuardPLC controllers.
Audience This manual is intended for engineers or technicians directly involved in the
installation and wiring of the Kinetix 6000 and Kinetix 7000 drives, and
programmers directly involved in the operation, field maintenance, and
integration of the Kinetix 6000 and Kinetix 7000 drives in a safe torque-off
application.
If you do not have a basic understanding of the Kinetix 6000 and Kinetix 7000
drives, contact your local Rockwell Automation sales representative for
information on available training courses.

Acronym Full Term Definition
EN European Norm
European Standards (EN specifications) developed by the European Committee for
Standardization for the European Union.
ISO
International Organization for
Standardization Voluntary organization whose members are recognized authorities on standards, each one
representing a different country.
IEC
International Electrotechnical
Commission
Non-profit, non-governmental international standards organization that prepares and
publishes international standards for all electrical, electronic, and related technologies,
collectively known as electrotechnology.
PL Performance Level EN ISO 13849-1 safety rating.
SIL Safety Integrity Level The measure of a products ability to lower the risk that a dangerous failure could occur.
PFD Probability of Failure on Demand The average probability of a system to fail to perform its design function on demand.
PFH Probability of Failure per Hour The probability of a system to have a dangerous failure occur per hour.
HFT Hardware Fault Tolerance
Equals N, where N+1 faults could cause the loss of the safety function. A hardware fault
tolerance of 1 means that 2 faults are required before safety is lost.
STO Safe Torque-off Functional safety feature that complies with IEC 61800-5-2.
IGBT Insulated Gate Bi-polar Transistors Typical power switch used to control main current.
