Preface
About This Publication This manual explains how the Kinetix® 6200 and Kinetix 6500 drives can be used
in Safety Integrity Level (SIL) CL3, Performance Level [PLe], or Category
(CAT) 4 applications. It describes the safety requirements, including PFD and
PFH values and application verification information, and provides information
on configuring and troubleshooting the Kinetix 6200 and Kinetix 6500 drives
with safe torque-off functionality.
Who Should Use This Manual Use this manual if you are responsible for designing, configuring, or
troubleshooting safety applications that use Kinetix 6200 or Kinetix 6500 drives
with safe torque-off functionality.
You must have a basic understanding of electrical circuitry and familiarity with
Kinetix 6200 and Kinetix 6500 drives. You must also be trained and experienced
in the creation, operation, and maintenance of safety systems.
Terminology The following table defines common safety terms used in this manual.
Table 1 - Common Safety Terminology
Abbreviation Full Term Definition
1oo2 One out of Two Refers to the behavioral design of a dual-channel safety system.
CAT Category –
EN European Norm The official European Standard.
ESPE Electro-sensitive Protective Equipment
An assembly of devices and/or components working together for protective tripping or presence-
sensing purposes and comprising as a minimum:
·a sensing device.
·controlling/monitoring devices.
·output signal-switching devices (OSSD).
FMEA Failure Mode and Effects Analysis
Analysis of potential failure modes to determine the effect upon the system and identify ways to
mitigate those effects.
IEC International Electrotechnical Commission –
IGBT Insulated Gate Bi-polar Transistors Typical power switch used to control main current.
HFT Hardware Fault Tolerance
The HFT equals
n, where n+1 faults could cause the loss of the safety function. An HFT of 1 means
that 2 faults are required before safety is lost.
MP Motion Power –
OSSD Output Signal-switching Device
The component of the electro-sensitive protective equipment (ESPE) connected to the control system
of a machine, which, when the sensing device is actuated during normal operation, responds by
going to the OFF-state.
PC Personal Computer Computer used to interface with and program your safety system.
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.
PL Performance Level ISO 13849-1 safety rating.
