Allen-Bradley 2094-AC05-MP5 - Wiring the Safe Torque-Off (STO) Connector

104 Rockwell Automation Publication 2094-UM001J-EN-P - March 2017
Chapter 5 Connect the Kinetix 6000 Drive System
Wiring the Safe Torque-off (STO) Connector
This example applies to any IAM or AM module equipped with the torque-off
(STO) connector.
Figure 53 - IAM/AM Module (STO connector)
Each IAM and AM module ships with the (9-pin) wiring-plug header and
motion-allowed jumper installed in the safe torque-off connector. With the
motion-allowed jumper installed, the safe torque-off feature is not used.
Pinouts for the torque-off (STO) connector are shown on page 60
.
Table 69 - Safe Torque-off (STO) Connector
To wire the safe torque-off connector in single axis or multi-axis
configurations, refer to the Kinetix Safe Torque-off Feature Safety Reference
Manual, publication GMC-RM002
