Safety Integrated for SINAMICS G120D
The PM250D Power Modules are generally prepared for SafetyIntegrated.
In conjunction with a standard Control Unit, the drive provides thesafety function STO.
In conjunction with a fail-safe Control Unit, the drive can beturned into a Safety Integrated Drive with comprehensive safetyfunctions.
The Safety Integrated functions are completely integrated into thedrive system. They can be activated via fail-safe digital inputs onthe Control Unit or via PROFINET or PROFIBUS with PROFIsafe.
The Safety Integrated functions are implemented electronically andtherefore offer short response times in comparison to solutionswith externally implemented monitoring functions.
Safety Integrated encoderless
The safety functions do not require a motor encoder; theimplementation effort is minimal. Existing machines in particularcan be updated with integrated safety technology without the needto change the motor or mechanical system.
The STO function can be used without any restrictions for allapplications.
The SS1, SLS, SSM and SDI functions are only permissible forapplications where the load can never cause acceleration. Anencoder that is used for the purposes of motor control has nosignificance for the safety functions here.
Control Units
The availability of Safety Integrated functions depends on the typeof Control Unit. Standard Control Units and fail-safe Control Unitsare available. All standard Control Units have STO.
The fail-safe Control Units offer Extended Functions (SLS, SDI,SSM) in addition to the Basic Functions (STO, SS1).
优势
Comparison between conventional and integrated safety systemsThe safety functions integrated into the drive can greatly reducethe effort required to implement safety concepts.
The integrated safety functions provide support when setting uptailored safety concepts. Configurations of safety concepts aregiven below based on the example of the SINAMICS G120D.
