Safe Torque Off Features
Kinetix 5100 servo drives have Safe Torque Off (STO) capability and can safely
turn off the inverter power transistors in response to the removal of the STO
digital inputs, resulting in Stop Category 0 behavior.
2198-Exxxx-ERS (hardwired) servo drives support parallel input terminals for
cascading to adjacent drives over duplex wiring. For applications that do not
require the STO safety function you must install jumper wires to bypass the safe
torque-off feature.
Refer to Safe Torque
Off Feature on page 384 for the STO connector pinout,
installation, and wiring information.
