Chapter 4 Connector Data and Feature Descriptions
Safe Torque-off Safety
Features Kinetix 5500 servo drives have safe torque-off (STO) capability and can safely
turn off the inverter power transistors in response to a monitored digital input,
according to Category 0 Stop behavior.
Servo Drives with Hardwired Safety
2198-H
xxx-ERS (hardwired) servo drives support parallel input terminals for
cascading to adjacent drives over duplex wiring. For applications that do not
require the STO safety function you must install jumper wires to bypass the safe
torque-off feature.
Refer to Chapter 9 on page 157 for the STO connector pinout, installation, and
wiring information.
Servo Drives with Integrated Safety
For 2198-H
xxx-ERS2 (integrated safety) servo drives, the 1756-L7xS
GuardLogix safety controller issues the STO command via the EtherNet/IP
network and the 2198-H
xxx-ERS2 servo drives execute the command.
Refer to Chapter 10 on page 167 for integrated safety drive specifications,
configuring motion and safety connections, motion direct commands, and the
STO bypass feature.
