Safety Integratedoverview
The availability of Safety Integrated functions depends on the typeof Control Unit. Standard Control Units and fail-safe Control Unitsare available.
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重庆西门子802D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.
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.重庆西门子802D数控系统代理商
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.
The SINAMICS G120C frequency converter offers the Safe TorqueOff (STO) function as a standard feature.
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 withPROFIsafe.重庆西门子802D数控系统代理商
The Safety Integrated function is implemented electronically andtherefore offers short response times in comparison to solutionswith externally implemented monitoring functions.
