The SINAMICS G120C frequency converter offers the Safe TorqueOff (STO) function as a standard feature.西门子802C数控系统代理商
The Safety Integrated function is completely integrated into thedrive system. It can be activated via fail-safe digital inputs onthe converter or via PROFINET or PROFIBUS with PROFIsafe.
The Safety Integrated function is implemented electronically andtherefore offers short response times in comparison to solutionswith externally implemented monitoring functions.西门子802C数控系统代理商
The PM240-2 and PM250 Power Modules are already designed for SafetyIntegrated.
In conjunction with a standard Control Unit, the drive provides thesafety function STO.
The PM240-2 Power Modules, frame sizes FSD to FSG additionallyoffer STO acc. to IEC 61508 SIL 3 andEN ISO 13489-1 PL e andCategory 3.西门子802C数控系统代理商
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 orvia 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 Integratedencoderless西门子802C数控系统代理商
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.
Safety Integratedoverview
The availability of Safety Integrated functions depends on the typeof Control Unit. Standard Control Units and fail-safe Control Unitsare available.西门子802C数控系统代理商
The CU240E-2 standard Control Units have STO and the CU250S-2Control Units have STO, SBC, and SS1 as standard.
The fail-safe Control Units offer Extended Functions (SLS, SDI,SSM) in addition to the Basic Functions (STO, SS1). The BasicFunction SBC is currently supported by the CU250S-2.
A license is required for operation of the Extended Functions onthe CU250S-2 Control Unit. It is of no consequence here whichSafety Integrated functions are used and how many.
The license can be ordered as an option with the memory card.Alternatively, a single-user license can also be purchased.
Safe BrakeRelay西门子802C数控系统代理商
The Safe Brake Control (SBC) function requires a Safe Brake Relay.The Safe Brake Relay allows safe control of electro-mechanicalmotor brakes.西门子802C数控系统代理商
The 24 V DC solenoid of the motor brake is directly connected tothe Safe Brake Relay. External surge suppressors are not required.The cable harnesses for connection to the Power Module are includedin the scope of supply.
With the Safe Brake Relay function, the brake is controlled inaccordance with IEC 61508 SIL 2 andEN ISO 13849-1 PL d and Category 3.
