Safe Torque Off Connector
Both the Kinetix 350 and Kinetix 5300 drives have a Safe Torque Off (STO)
connector. The STO pinouts are different between the two drives. See
for a comparison of the two connectors. See the Kinetix 350
Single-axis EtherNet/IP Servo Drive User Manual, publication
for information on STO with the Kinetix 350 drive. See the Kinetix 5300 Single-
axis EtherNet/IP Servo Drives User Manual, publication
information on STO with the Kinetix 5300 drive.
The Kinetix 350 drive ships with the 6-pin wiring-plug that connects your
safety circuit to the Kinetix 350 drive safe torque-off (STO) connector.
The Kinetix 5300 10-pin connector consists of two parallel 5-pin rows for
cascading safety connections from drive-to-drive when drives are joined by the
zero-stack feature.
