STO (Safe Torque Off) conventionally wired
High wiring time & costs as a result of the safety relay and contactors. No protection against manipulation of the safety functions. Intensive service is required due to the mechanical shutdown (contact us). The power-on cycles of the converter have to be taken into consideration as it is disconnected from the line supply. No diagnostics of the converter as the status display is no longer available after shutdown.
After the Emergency Stop button has been pressed, the contactor safety combination opens the two line contactors K1 and K2 and the motor coasts down unbraked.

STO (Safe Torque Off) using the safety digital inputs of SINAMICS G120
After the Emergency Stop pushbutton has been pressed, the firing pulses of the power unit are cancelled in SINAMICS G120 in a safety-relevant fashion and the drive coasts down unbraked. Caution! The motor is not electrically isolated from the line supply.
Cost saving as a result of minimized wiring costs and space-saving as the Emergency Stop pushbutton is directly connected to the SINAMICS G120 digital inputs without using a safety contactor combination.
Risks are minimized for the plant construction company by using password-protected safety parameters in SINAMICS G120.
No wearing parts as the shutdown is electronic. SINAMICS G120 remains connected to the line supply and its full diagnostics capability is retained.

SS1 (Safe Stop 1) using conventional wiring
While the drive is stopped using OFF3 motion is not monitored. -> If a fault condition develops the drive can accelerate and is only shut down after the time delay has expired (typ. 3s).
High wiring costs as a result of the safety relay and contactors. It is easy to change the value of the time delay without any specific authorization.
After pressing the Emergency Stop pushbutton a fast stop is activated in the converter via OFF 3 and the drive then brakes.
The contactor safety combination opens the two line contactors K1 and K2 after a time delay (typ. 3s) (controlled stopping with a safely monitored deceleration time).

SS1 (Safe Stop 1) using the safety digital inputs of the SINAMICS G120
While the drive is stopping, motion is continually monitored. If the drive does not follow/track the parameterized ramp then STO is immediately initiated.
Speed feedback is not required using an encoder for the safety function. Cost saving as a result of minimized wiring costs and space saving as the Emergency Stop pushbutton is directly
connected to the SINAMICS G120 via the safety digital inputs without safety contactor combination. Risks are minimized for the plant construction company by using password-protected safety parameters in G120.
After pressing the Emergency Stop button the Safe Stop 1 safety function in the SINAMICS G120 is activated and the drive is decelerated using the safety ramp function. At zero speed (from 2 Hz and below) STO is activated (controlled stopping with safely monitored braking ramp). Caution ! The motor is not electrically isolated from the line supply.

SLS (Safely Limited Speed) using conventional wiring
Extremely high wiring costs as a result of several safety relays and contactors. A speed encoder, two initiators and a safety-relevant speed monitor are required to sense the speed.
There is no protection against the safety functions being manipulated. Intensive maintenance & service required as there are many independent monitoring devices and mechanical shutdown.
The converter is shut down if the speed is exceeded.

SLS (Safely Limited Speed) using the safety digital inputs of the SINAMICS G120
After SLS is activated - depending on the parameterized mode - the drive is decelerated to the parameterized SLS (Safety Limited Speed) or, if the speed is exceeded, STO is activated. In addition, there is still a second safety function available – such as STO or SS1. Caution! It is not possible to accelerate to the SLS (Safely Limited Speed) from standstill (zero speed).
Neither external monitoring devices nor speed encoder required as the safety function is integrated in SINAMICS G120 without any encoder (sensorless).
When SLS is activated, the deceleration ramp is immediately monitored and the speed limited. STO is immediately initiated if the drive does not follow/track the parameterized ramp or the parameterized SLS speed is exceeded.
Cost saving through minimum wiring costs and space saving as the safety sensors (Emergency Stop pushbutton, light curtains etc.) are directly connected to G120 via the safety digital inputs without requiring a safety contactor combination.
Risks are minimized for the plant construction company by using password-protected safety parameters in the G120.
