9.3 Option K82 (Terminal module for controlling the “Safe Torque Off” and “Safe Stop1”
functions)
This option is available for SINAMICS G150, SINAMICS S120 Cabinet Modules (only for air-cooled units, but not
currently for liquid-cooled units), SINAMICS S150.
The Safe Torque Off (STO) function prevents a motor from starting unexpectedly from standstill. The Safe Stop1
(SS1) function is braking the rotating motor along a deceleration ramp followed by the transition to STO and thus
reliably preventing the motor from restarting. These two safety functions are a standard feature of SINAMICS G150
converter cabinet units, S120 Cabinet Modules and S150 converter cabinet units.
