Safety Technology Integrated In The Drive - Siemens SINUMERIK 840D sl Function Manual

Brief description

3.3 Safety technology integrated in the drive

● Safe Operating Stop (SBH)
Monitors the drives during standstill (to ensure that they remain stationary). The drives
remain fully functional in closed-loop control.
● Safely reduced speed (SG) including override
Configured speed limits are monitored, e.g. when setting-up without using an agreement
button.
● Safe speed range detection "n<n
This is used to detect the velocity range of a drive in a safety-related fashion.
● Safe software limit switches (SE)
Variable traversing range limits
● Safe software cams and Safe Cam Track (SN)
Range detection
● Safety-relevant input/output signals (SGE/SGA)
Interface to the process
● Safety-related communication via standard bus
Distributed I/O for process and safety signals are connected via PROFIBUS and
PROFINET using the PROFIsafe profile.
● Safety-related CPU-CPU communication
Safety-relevant communication between safety-relevant controls to implement hierarchic
systems, e.g. transfer lines.
● Safe programmable logic (SPL)
Direct connection of all safety-related signals and their internal logical interconnection.
● Safe brake management (SBM)
Safety-related two-channel brake control (SBC) and cyclic brake test (SBT).
● Integrated acceptance test
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.
3.3 Safety technology integrated in the drive
SINAMICS Safety Integrated
The SINAMICS S120 drive system provides the Safety Integrated Basic Functions and the
Safety Integrated Extended Functions.
Under certain limitations and constraints (refer to the system prerequisites), the Safety
Integrated Basic Functions can be used together with SINUMERIK 840D sl.
They can be activated via terminals at the power unit and at the NCU or at the NX module.
