Kinetix 5500 Safe Torque-off - Integrated Safety
Safe Torque-off Feature
The safe torque-off feature, when used with suitable safety components, provides
protection according to EN ISO 13849 (PLe), Category 3 or according to
IEC 61508, EN 61800-5-2, and EN 62061 (SIL CL3). The safe torque-off
option is just one safety control system. All components in the system must be
chosen and applied correctly to achieve the desired level of operator safeguarding.
The safe torque-off feature is designed to safely turn off all of the output power
transistors. You can use the safe torque-off feature in combination with other
safety devices to achieve category 0 stop and protection-against-restart as
specified in IEC 60204-1.
Out-of-Box State
The 2198-H
xxx-ERS2 servo drives ship in the out-of-box state.
In the out-of-box state, you can configure 2198-H
xxx-ERS2 servo drives:
• Without a GuardLogix® 5570 safety controller for a non-safety
application.
• With a GuardLogix 5570 safety controller when the safe torque-off
(STO) function is not required.
Out-of-Box State Support
After the integrated safety connection configuration is applied to the
2198-H
xxx-ERS2 servo drive at least once, you can restore the drive to the out-
of-box state.
ATTENTION: This option is designed to restrict motion producing power on the
drive system or affected area of a machine. It does not provide electrical safety.
SHOCK HAZARD: In Safe Torque-off mode, hazardous voltages can still be
present at the drive. To avoid an electric shock hazard, disconnect power to the
system and verify that the voltage is zero before performing any work on the
drive.
ATTENTION: Personnel responsible for the application of safety-related
programmable electronic systems (PES) shall be aware of the safety
requirements in the application of the system and shall be trained in using the
system.
ATTENTION: In the out-of-box state, motion producing power is allowed by the
safe torque-off (STO) function unless an integrated safety connection
configuration has been applied to the drive at least once.
