Connector Data and Feature Descriptions
Safe Torque-off Connector Pinout
Each 2094-
xCxx-Mxx-S IAM module and 2094-xMxx-S AM module ships with
the (9-pin) wiring-plug header and motion-allowed jumper installed in the safe
torque-off (STO) connector. With the motion-allowed jumper installed, the safe
torque-off feature is not used.
Figure 25 - Motion-allowed Jumper
Headers in this table extend the 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 feature.

IMPORTANT
Pins STO-8 and STO-9 (24V+) are used by only the motion-allowed jumper.
When wiring to the wiring-plug header, the 24V supply must come from an
external source.
