Kinetix 5700 Safe Torque-off Function
Chapter 9
Integrated Safe Torque-off
This section introduces you to the Kinetix 5700 safe torque-off (STO) feature
over the EtherNet/IP network that meets the requirements of Performance
Level e (PL e) per ISO 13849-1 and SIL 3 per IEC 61508, IEC 61800-5-2, and
IEC 62061. Integrated STO applies to 2198-
xxxx
-ERS3 and 2198-
xxxx
-ERS4
dual-axis and single-axis inverters.
In Integrated STO mode, the GuardLogix® safety controller issues the STO
command over the EtherNet/IP network and the 2198-
xxxx
-ERS3 and
2198-
xxxx
-ERS4 dual-axis and single-axis inverters execute the STO
command.
Compatible Safety Controllers
A GuardLogix 5570 or Compact GuardLogix 5370 safety controller is
required for integrated safety control of the Kinetix 5700 safe torque-off
function.
The Studio 5000 Logix Designer application, version 26.00 or later, provides
support for programming, commissioning, and maintaining Logix5000™ safety
controllers with Kinetix 5700 drive systems.
The safety connection can originate from either of these controller
configurations:
• Single safety controller that provides both safety and motion control
• Safety controller that controls only the safety, while a separate
ControlLogix 5570, ControlLogix 5580, CompactLogix 5370, or
CompactLogix 5380 controller that controls motion

Safety Application Requirements
Safety application requirements include evaluating probability of failure rates
(PFH), system reaction time settings, and functional verification tests that
fulfill SIL 3 criteria. Refer to
Average Frequency of a Dangerous Failure
on
for more PFH information.
Creating, recording, and verifying the safety signature is also a required part of
the safety application development process. Safety signatures are created by the
safety controller. The safety signature consists of an identification number,
date, and time that uniquely identifies the safety portion of a project. This
includes all safety logic, data, and safety I/O configuration.
