Kinetix 300 Drive Safe Torque-off Feature Chapter 8
Safe Torque-off Wiring Requirements
These are the safe torque-off (STO) wiring requirements. Wire should be copper
with 75 °C (167 °F) minimum rating.
Safe Torque-off (STO) Terminal Plug
IMPORTANT The National Electrical Code and local electrical codes take precedence over the
values and methods provided.
IMPORTANT Stranded wires must terminate with ferrules to prevent short circuits, per table
D7 of EN 13849.

IMPORTANT Pins STO-1 (+24V DC Control) and STO-2 (Control COM) are used only by the
motion-allowed jumpers to defeat the safe torque-off function. When the safe
torque-off function is in operation, the 24V supply must come from an external
source.
IMPORTANT To be sure of system performance, run wires and cables in the wireways as
established in the user manual for your drive.
