Safety-related parts are designed with these attributes:
•A single fault in any of these parts does not lead to the loss of the safety
function.
•A single fault is detected whenever reasonably practicable.
•Accumulation of undetected faults can lead to the loss of the safety
function, which results in failure to remove motion-producing power from
the motor.
Stop Category Definition
Stop category 0 as defined in EN 60204 or Safe Off as defined by EN 61800-5-2
is achieved with immediate removal of motion-producing power to the actuator.

Rockwell Automation Publication GMC-RM002F-EN-P - June 2013 11
Safety Concept and Troubleshooting Chapter1
Low Voltage Directive
These units are tested to meet Council Directive 2006/95/EC Low Voltage
Directive. The EN 60204-1 Safety of Machinery-Electrical Equipment of
Machines, Part 1-Specification for General Requirements standard applies in
whole or in part. Additionally, the standard EN 61800-5-1 Electronic
Equipment for use in Power Installations apply in whole or in part.
Refer to the Kinetix Servo Drives Specifications Technical Data, publication
GMC-TD003, for environmental and mechanical specifications.
Description of Operation The safe torque-off feature provides a method, with sufficiently low probability
of failure, to force the power-transistor control signals to a disabled state. When
disabled, or any time power is removed from the safety enable inputs, all of the
drive output-power transistors are released from the On-state. This results in a
condition where the drive is coasting (stop category 0). Disabling the power
transistor output does not provide mechanical isolation of the electrical output,
which may be required for some applications.
Under normal operation, the safe torque-off inputs are energized. If either of the
safety-enable inputs are de-energized, then all of the output power transistors will
turn off. The safe torque-off response time is less than 25 ms.
PFD and PFH Specifications Safety-related systems can be classified as operating in either a Low Demand
mode, or in a High Demand/Continuous mode:
•Low Demand mode: where the frequency of demands for operation made
on a safety-related system is no greater than one per year or no greater than
twice the proof-test frequency.
•High Demand/Continuous mode: where the frequency of demands for
operation made on a safety-related system is greater than once per year.
The SIL value for a low demand safety-related system is directly related to order-
of-magnitude ranges of its average probability of failure to satisfactorily perform
its safety function on demand or, simply, average probability of failure on demand
(PFD). The SIL value for a High Demand/Continuous mode safety-related
system is directly related to the probability of a dangerous failure occurring per
hour (PFH).
ATTENTION: Permanent magnet motors can, in the event of two simultaneous
faults in the IGBT circuit, result in a rotation of up to 180 electrical degrees.

Chapter 1 Safety Concept and Troubleshooting
PFD and PFH Data
These PFD and PFH calculations are based on the equations from IEC 61508
and show worst-case values. Ta ble 1 provides test data and demonstrates the
worst-case effect of various configuration changes on the data.
Table 1 - PFD and PFH Proof Test Interval
Determination of safety parameters is based on the assumption that the system
operates in High Demand mode and that the safety function is requested at least
once a year.
PFH and PFD determination was performed without considering external wiring
failure modes, as described in EN ISO 13849-2. Depending on the application,
consider taking measures to exclude these failure modes.
To proof test the safe torque-off function, you must interrupt power to the safe
torque-off function inputs (STO-5 and STO-7) and verify the drive is in the
disabled state. Refer to the Safe Torque-off Connector Pinout on page 15, for
signal descriptions and pinouts.
Troubleshooting The safe-off fault (E49) is detected upon demand of the safe-off function.

Safety Concept and Troubleshooting Chapter1
Understanding the Safe Torque-off Condition vs Drive Fault
When both inputs de-energize within 100 ms, a fault does not occur (E49 is not
displayed), however, a safe torque-off state is entered within the 25 ms response
time. The safe torque-off condition occurs through normal drive operation.
A mismatch occurs when one input is de-energized while the other input is
energized after 100 ms. This causes the E49 error code to display and the drive
begins a shutdown sequence. Causes for a mismatch include:
•wiring anomalies at the Safe Torque-off (STO) connector, pins STO-5 and
STO-7, or the external monitoring relay.
•input anomalies associated with the Safe Torque-off (STO) connector,
pins STO-5 and STO-7.
•sequencing errors in the program.
•EMI interference.
To determine if you have a safe torque-off fault or condition, you must examine
the Axis_Servo_Drive status bit in RSLogix 5000 software.
•If bit status is 0, then no safe torque-off condition or fault exists.
•If bit status is 1, then a safe torque-off condition or fault does exist.
Figure 1 - RSLogix 5000 Software, Version 15 Safe Torque-off Status Bit
In the RSLogix 5000, version 15 example, the axis.DriveStatus.14 bit is set to 0,
indicating the drive is not in Safe Torque-off mode. No safe torque-off condition
or fault exists.
Figure 2 - RSLogix 5000 Software, Version 16 (or later) Safe Torque-off Status Bit
In the RSLogix 5000, version 16 example, the axis.SafeOffModeActiveStatus bit
is set to 0, indicating the drive is not in Safe Torque-off mode. No safe torque-off
condition or fault exists.

Figure 3 - Advanced Safe Torque-off Troubleshooting Flowchart
(1) This is a safe torque-off condition because the safe torque-off status bit is set to 1 without an E49 error code. After the condition is
fixed, the motion planner must be signaled that the position loop has opened in the condition state with a Motion Servo Off (MSF)
instruction before the next Motion Servo On (MSO) instruction can take place. The MSF instruction is necessary because the drive is
enabled and running.
(2) This is also a safe torque-off condition (the safe torque-off status bit is set to 1 without an E49 error code). The safe torque-off
condition must be resolved, but because the drive is not enabled and running the MSF instruction is not necessary.

Safe Torque-off Header
Configurations
The safe torque-off function can be implemented in a single-drive or extended in
up to eight drives in a multiple safety-drive configuration. The connector can also
be jumpered to effectively remove the safe torque-off function.
In this example, the Kinetix 6000 axis module is shown with the motion-allowed
jumper installed in the wiring plug header. This header/jumper combination
(default configuration) ships with each Kinetix 6000 and Kinetix 7000 drive and
enables drive operation without external safety-circuit connections.
Figure 6 - Motion-allowed Jumper
In this example, the Kinetix 6000 axis module is shown with a wiring plug header.
The motion-allowed jumper has been removed. Use the wiring plug header alone
for wiring Kinetix 6000 and Kinetix 7000 single drive safe torque-off
applications.

Chapter 2 Safe Torque-off Connector Data
In this example, the Kinetix 6000 axis module is shown with a first-drive wiring
header (catalog number 2090-XNSM-W). Kinetix 6000 and Kinetix 7000 first-
drive modules use this header in multiple safe torque-off drive configurations for
wiring to a safety control circuit and extending the safe torque-off circuitry to
another drive.

Safe Torque-off Connector Data Chapter2
In this example, the Kinetix 6000 axis module is shown with a drive-to-drive
middle header (catalog number 2090-XNSM-M). Kinetix 6000 and
Kinetix 7000 drive modules, in safe torque-off drive configurations of three or
more, use this header for making the safe torque-off connections between drives.
Figure 10 - Middle Drive Header (2090-XNSM-M)
In this example, the Kinetix 6000 axis module is shown with a last-drive
terminating header (catalog number 2090-XNSM-T). Kinetix 6000 and
Kinetix 7000 drive modules use this header in multiple safe torque-off drive
configurations for making safe torque-off connections to the last drive.
