Safe Torque-off Connector Pinout
The Kinetix 350 drive ships with the (6-pin) wiring-plug header that connects
your safety circuit to the Kinetix 350 drive safe torque-off (STO) connector. If
your system does not use the safe torque-off feature, follow instructions in
to wire the drive with motion-
allowed jumpers.

IMPORTANT
Use only pins STO-1 (+24V DC Control) and STO-2 (Control COM) of the motion-
allowed jumpers to enable the drive when the safe torque-off function is not
used. When the safe torque-off function is in operation, the 24V supply must
come from an external source.
