Kinetix 5100 Safe Torque Off (STO) Feature
Chapter 13
Wire the Safe Torque Off
Circuit
This section provides guidelines for wiring your Kinetix 5100 Safe Torque Off
(STO) drive connections.
Safe Torque Off Wiring Requirements
The Safe Torque Off (STO) connector uses spring tension to secure the wire.
Depress the orange tab along side each pin to insert or release the wire. Wire must
be copper with 75 °C (167 °F) minimum rating.

IMPORTANT
The National Electrical Code and local electrical codes take precedence over the
values and methods provided.
IMPORTANT
To improve system performance, run wires and cables in the wireways as
established in Establish Noise Zones beginning on page 33 .
IMPORTANT
Pins SB+ and SB– are used to disable the safe torque-off function. When
wiring to the STO connector, use an external 24V supply for the external safety
device that triggers the safe torque-off request. To avoid jeopardizing system
performance, do not use pin SB+ as a power supply for the external safety
device.
IMPORTANT
Stranded wires must terminate with ferrules to prevent short circuits, per table
D.4 of ISO 13849-2:2012.
