Functional Safety Features
Kinetix 5700 drives have the capability to safely turn off the inverter power
transistors in response to a monitored digital input, in accordance with Stop
Category 0 behavior. Hardwired and integrated safety options are available on
all Kinetix 5700 servo drives.
Hardwired STO Mode
Hardwired safe torque-off (STO) mode supports parallel input terminals for
cascading to adjacent drives over duplex wiring. For applications that do not
require the safety function you must install jumper wires to bypass the safe
torque-off feature. This applies to 2198-xxxx-ERS3 and 2198-xxxx-ERS4
inverters.
Refer to Hardwired Safe Torque-off
on page 314 for the STO connector
pinout, installation, and wiring information.
Integrated Mode
For 2198-xxxx-ERS3 inverters in integrated STO mode, when any
GuardLogix® or Compact GuardLogix safety controller issues the safe torque-
off (STO) command over the EtherNet/IPâ„¢ network and the Kinetix 5700
drives execute the STO commands.
Refer to Integrated Safe Torque-off
on page 323 for integrated safety drive
specifications, configuring motion and safety connections, direct motion
commands, and the STO bypass feature.
For 2189-xxxx-ERS4 inverters in integrated mode, the GuardLogix 5580 or
Compact GuardLogix 5380 safety controller activates the Monitored SS1
stopping function or any of the Drive Safety instructions providing controller-
based safety functions over the EtherNet/IP network.
For 2189-xxxx-ERS4 and 2189-xxxx-ERS3 (series B) drives, Timed SS1 and
STO are drive-based safety functions that are activated by the
GuardLogix 5580 or Compact Guardlogix 5380 controller over the
EtherNet/IP network.
Refer to the Kinetix 5700 Safe Monitor Functions Safety Reference Manual,
publication 2198-RM001
, for a description and configuration examples of the
integrated stopping functions in the Studio 5000 Logix Designer® application.
