The safety functions are available in all modes and can communicate with the process using safety-oriented input/output signals. They can be implemented for each individual axis and spindle. Safety Integrated drive-based (basic version)- Safe Torque Off (STO)
Suppression of drive pulses, providing safe electronic interruption of the energy supply - Safe Brake Control (SBC)
Safe, 2-channel control of a holding brake – integrated in the SINAMICS S120 Motor Module - Safe Stop 1 (SS1)
Safe shutdown of a drive, with subsequent transition into the STO state
Safety Integrated system-integrated (option)- Safe shutdown
Ensures safe transition of the drive from motion to standstill when a monitoring device or sensor (e.g. light barrier) responds
, optimally adapted to the operating conditions of the machine. - Safe Brake Ramp (SBR)
Monitoring of speed curve – after a stop request, the speed must be reduced - Safe Operating Stop (SBH, SOS)
Monitors drives for standstill – the drives remain fully functional in the position control - Safe standstill (SH, STO)
Suppression of drive pulses, providing safe electronic interruption of the energy supply - Safely Limited Speed (SG, SLS)
Monitoring of configurable speed limits, e.g. in setup mode - Safety-related output n < nx
Safe speed recognition of a drive - Safe software limit switches (SE, SLP)
Variable traversing range limitation - Safe software cams (SN)
Range recognition - Safety-related input/output signals (SGE/SGA)
Interface with process - Safe programmable logic (SPL)
Direct connection of all safety-related signals and their internal logic operation - Safe brake management (SBM)
- Safe Brake Control (SBC)
2-channel braking signal – integrated in the SINAMICS S120 Motor Module - Safe Brake Test (SBT)
Cyclic brake test
- Safety-related communication via standard bus
- Connection of distributed I/O for process and safety signals via PROFIBUS/PROFINET using the PROFIsafe protocol
- Safety-related CPU – CPU communication via PROFIBUS/PROFINET
- Integrated acceptance test with SINUMERIK Operate
Partially automated acceptance test for all safety-related functions. Simple operation of the test process, automatic configuration of trace functions and automatic generation of an acceptance record.
