Safe Torque-off Connector Data
This chapter provides safe torque-off (STO) connector, header, and interface
cable information for the Kinetix 6000 and Kinetix 7000 safe torque-off drives.
Safe Torque-off Connector
Pinout
Headers are available to extend the 9-pin safe torque-off (STO) connector
signals for use in wiring single and multiple safe torque-off drive configurations,
or to defeat (not use) the safe torque-off function.

Description Signal
1
• Wiring plug header used in
single-drive applications
• First-drive wiring header
(2090-XNSM-W) used in
multiple-drive applications
One side of the normally-closed monitoring contact of relay 2 FDBK2+
2 Other side of the normally-closed monitoring contact of relay 2 FDBK2-
3 One side of the normally-closed monitoring contact of relay 1 FDBK1+
4 Other side of the normally-closed monitoring contact of relay 1 FDBK1-
5 Safety enable 2 input SAFETY ENABLE2+
6 Return for safety enable power (both inputs) SAFETY ENABLE-
7 Safety enable 1 input SAFETY ENABLE1+
8
• Wiring plug header
• Motion-allowed jumper
Output power for continuous enable of the safety function, 500 mA, max 24V+
9 Output power return used for continuous enable of safety function 24V_COM
IMPORTANT
Pins STO-8 (internal 24V+ supply) and STO-9 (24V_COM) are used only by the
motion-allowed jumper 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.
