Disable the Safe Torque-off Feature
The safe torque-off circuit is designed to safely turn off all of the output-power transistors. Each Kinetix 5500
drive ships with two 5-pin wiring plugs for wiring to safety devices. If your application, for example, the one used
in this quick start, does not include safety devices, you must disable the safe torque-off feature.
The safe torque-off (STO) connector uses spring tension to secure the wire. Depress the tab, along side each pin,
to insert or release the wire. Two rows of pins are provided for drive-to-drive connections.
Safe Torque-off (STO) Terminal Plug Wiring
To bypass the safety function, these signals
should be wired as shown. With the jumper
wires installed, the safe-off feature is not used.
IMPORTANT Stranded wires must terminate with ferrules to prevent short circuits, per table D7 of EN 13849.
