With the SSM function, in the simplest case, a safety door can beunlocked if the speed drops below a non-critical level. Anothertypical example is that of a centrifuge that may be filled onlywhen it is operating below a configured speed limit. 
Customerbenefits西门子中国代理商|模块授权代理商
Unlike SLS, there is no drive-integrated fault reaction when thespeed limit is exceeded. The safe feedback can be evaluated in asafety control unit, allowing the user to respond appropriately tothe situation.
The SDI function ensures that the drive can only move in theselected direction.
Effect西门子中国代理商|模块授权代理商
Deviation from the direction of motion currently being monitored isdetected reliably and the configured drive-integrated faultreaction is initiated. It is possible to select which direction ofrotation is to be monitored.
Application
The SDI function is used when the drive may only move in onedirection. A typical application is to permit the operator accessto a danger zone, as long as the machine is rotating in the safedirection, i.e. away from the operator. In this state, the operatorcan feed material into the work zone or remove material from thework zone without danger.
Customerbenefits西门子中国代理商|模块授权代理商The function saves the use ofexternal components such as speed monitors and the associatedwiring. The release of a danger zone while the machine is movingaway from the operator increases productivity. Without the SDIfunction, the machine must be safely stopped during materialloading and removal.
The SLA function monitors that the drive does not exceed a presetacceleration limit value.
The SLA function monitors that the motor does not violate thedefined acceleration limit (e.g. in setup mode). SLA detects earlyon whether the speed is increasing at an inadmissible rate (thedrive accelerates uncontrollably) and initiates the stopresponse.
The SLA function is used, e.g., for SIMATIC Safe Kinematics. SLAcan only be used in safety systems with an encoder.
Customerbenefits西门子中国代理商|模块授权代理商The function monitors for maximumpermissible acceleration in setup mode and safe monitoring of thetool center point with different kinematics.
The SLP function monitors the axis to ensure that it remains withinthe permissible traversing range.

Application
SOS is an ideal solution for all those applications for which themachine or parts of the machine must be at a safe standstill forcertain steps, but the drive must also supply a holding torque. Itis ensured that despite counter torque the drive remains in itscurrent position. In contrast to SS1 and SS2, the drive does notbrake autonomously in this case. It expects the higher-levelcontroller to ramp down the relevant axes as a coordinated groupwithin an adjustable delay time. This can be used to prevent anydamage to the machine or product. Typical applications for SOSinclude winders, converting and packaging machines and machinetools.
Customerbenefits西门子中国代理商|模块授权代理商
No mechanical components are necessary to keep the axis in positiondespite any counterforce that may occur. Due to the short switchingtimes and the fact that the drive control always remains active,setup and downtimes are reduced. Recalibration of the axis afterexiting the SOS function is not necessary. The axis can immediatelybe moved again after deactivation of the SOS function.
The SBC function permits the safe control of a holding brake. SBCis always activated in parallel with STO.
Effect西门子中国代理商|模块授权代理商
A holding brake which is active in a de-energized state iscontrolled and monitored using safe two-channel technology. Due tothe two-channel control, the brake may still be activated in theevent of an insulation fault in the control cable. Errors of thiskind are detected early by means of test pulses.
Note:西门子中国代理商|模块授权代理商
Safe Brake Control does not detect mechanical faults in the brakeitself, such as worn brake linings. For Motor Modules in booksizeformat, the terminals for the motor brake are integrated. Anadditional Safe Brake Relay is required for Power Modules inblocksize format. An additional Safe Brake Adapter is necessary forPower Modules in chassis format.
Application西门子中国代理商|模块授权代理商
The SBC function is used in conjunction with the functions STO orSS1 to prevent the movement of an axis in the tor state,e.g. because of gravity.
Again, the function saves the use of external hardware and theassociated wiring.
The SBT diagnostic function carries out a brake function test atregular intervals or before personnel enter the danger zone.
Effect
A good way to check the proper functioning of brakes that havebecome worn is to apply a torque to the closed brake. Drive systemsthat have two brakes, e.g. motor brake and external brake, can betested with different torque values.
The SBT diagnostic function is suitable for implementing a safebrake in combination with the SBC function.
Customer benefits
The function detects faults or wear in the brake mechanics.Automatically testing the effectiveness of brakes reducesmaintenance costs and increases the safety and availability of themachine or plant.
The SLS function monitors the drive to ensure that it does notexceed a preset speed or velocity limit.
The SLS function monitors the drive against a parameterized speedlimit. Four different limit values can be selected. As in the caseof SOS, the speed setpoint is not influenced independently. AfterSLS has been selected, the higher-level control must bring thedrive down below the selected speed limit within a parameterizabletime. If the speed limit is exceeded, a customizabledrive-integrated fault reaction occurs.
The SLS limit stage 西门子中国代理商|模块授权代理商1 can be multiplied by afactor that is transferred in 16-bit resolution via PROFIsafe. Thisallows an almost unlimited number of limits to be specified.
The SLS function is used if people are in the danger zone of amachine and their safety can only be guaranteed by reduced speed.Typical application cases include those in which an operator mustenter the danger zone of the machine for the purposes ofmaintenance or setting up, such as a winder in which the materialis manually threaded by the operator. To prevent injury to theoperator, the roller may only spin at a safely reduced speed. SLSis often also used as part of a two-stage safety concept. While aperson is in a less critical zone, the SLS function is activated,and the drives are only stopped safely in a smaller area withhigher potential risk. SLS can be used not only for operatorprotection, but also for machinery protection, e.g. if a maximumspeed must not be exceeded.
The SLS function can contribute to a significant reduction indowntime, or greatly simplify or even accelerate setup. The overalleffect achieved is a higher availability of the machine. Moreover,external components such as speed monitors can be omitted.
The SSM function warns when a drive is working below an adjustablespeed limit. As long as it remains below the threshold, thefunction issues a safety-related signal.
If a speed value drops below a parameterized limit, asafety-related signal is generated. This can, for example, beprocessed in a safety control unit to respond to the event byprogramming, depending on the situation.
