Wiring Your Kinetix Safe Torque-off Drive Chapter 3
Safe Torque-off Wiring Examples for SIL 3 Applications
The following illustrations show typical wiring diagrams for the Kinetix 6000
and Kinetix 7000 safe torque-off drives:
• Typical single drive (stop category 0) configuration
• Typical single drive (stop category 1) configuration
Figure 16 - Single Drive (Stop Category 0) with Safety Relay Configuration
ATTENTION: Category 1 (controlled stop) must be used and zero speed verified,
prior to engaging the motor holding (parking) brake. Disabling the output by
any means and engaging the holding brake with the motor in motion will result
in premature failure of the brake.

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.
