Preconditions For Safety Integrated Basic Functions - Siemens SINAMICS G130 Manual

General information about SINAMICS Safety Integrated

2.2 Preconditions for Safety Integrated Basic Functions

● Safety Integrated Extended Functions
2.2 Preconditions for Safety Integrated Basic Functions
The following prerequisites apply for operation of the Safety Integrated Basic Functions:
● For G150, S120 Cabinet Modules and S150: Option K82 (terminal module for activation
● An activated speed controller in the drive
36
These functions require an additional safety license:
– Safe Torque Off (STO)
STO is a safety function that prevents the drive from restarting unexpectedly, in
accordance with EN 60204-1, Section 5.4.
– Safe Stop 1 (SS1, time and acceleration controlled)
The SS1 function is based on the "Safe Torque Off" function. This means that a
Category 1 stop in accordance with EN 60204-1 can be implemented.
– Safe Stop 2 (SS2)
The SS2 function brakes the motor safely with a subsequent transition to "Safe
Operating Stop" (SOS). This means that a Category 2 stop in accordance with EN
60204-1 can be implemented.
– Safe Operating Stop (SOS)
SOS protects against unintentional movement. The drive is in closed-loop control
mode and is not disconnected from the power supply.
– Safely-Limited Speed (SLS)
The SLS function ensures that the drive does not exceed a preset speed limit.
– Safe Speed Monitor (SSM)
The SSM function safely monitors the speed limit and issues a safe output signal, but
without initiating a response function.
– Safe Acceleration Monitor (SBR)
The function monitors the safe braking of the drive during the ramp down. An
unintentional "reacceleration" is reliably prevented.
This is part of the SS1 and SS2 functions.
– Safe Brake Ramp (SBR)
The Safe Brake Ramp function safely monitors a braking ramp.
This is part of the SS1 functions without encoder and SLS without encoder.
of the safety functions "Safe Torque Off" and "Safe Stop 1"), at activation signals of 230 V
and/or cable lengths of more than 30 m
