VLT® Safety Option MCB 152
The VLT® Safety Option MCB 152 operates the safety functions of a frequency converter via the PROFIsafe fieldbus. It improves flexibility by connecting safety devices within a plant.
The MCB 152 is a preferred choice for highly flexible machines with modular and variable quantity of safety zones in any manufacturing production line. Central and decentral drives located at different machinery cells can easily be interconnected with the PROFIsafe safety fieldbus. This interconnection enables activation of Safe Torque Off (STO) irrespective of where a hazard occurs. The safety functions of the
MCB 152 are implemented according to
EN IEC 61800-5-2.
PROFIsafe
functionality certified by PNO
Fieldbus Safe Torque Off (STO) with VLT® AutomationDrive
The MCB 152 supports PROFIsafe functionality to activate integrated safety functions of the VLT® AutomationDrive from any PROFIsafe host, up to
Safety Integrity Level SIL 2 according to EN IEC 61508 and EN IEC 62061
Performance Level PL d, Category 3 according to EN ISO 13849-1
Fieldbus profiles like PROFIsafe, PROFIdrive and FC-Profile are elements of the PROFINET fieldbus. This permits the transmission of standard and safetyrelated data on a single bus cable.
The existing network infrastructure is optimally utilised, since no separate cabling is required.
PROFIsafe device
The combination of VLT® Safety Option MCB 152, VLT® PROFINET MCA 120 fieldbus option and VLT® AutomationDrive FC 302 constitutes a PROFIsafe device.
Purchase the drive fully-configured from the factory, or retrofit options in the field – whatever is the best fit for your business.

Benefit
–Provides the safety function STO (Safe Torque O )
–Fewer safe I/O cards are required in the PLC
–Reduced wiring due to decentralisation
–Simple selection, confi guration, project planning, and installation
–Easy to confi gure via the MCT 10 safe plug-in
–Connect door switches or emergency stop switches directly to the drive
–Select whether the inputs directly activate the STO, or if the failsafe controller monitors the safe inputs for use in its failsafe program
–Enables control of external devices that are not connected with PROFIsafe
–Usable in a wide range of safety applications
–More advanced functions can be implemented by programming the safety PLC, for example guard interlocking, two-hand control or SS1
–Increased plant availability possible by formation of safe I/O groups
–High level of fl exibility when expanding plants
–Drives already running on PROFINET are easy to upgrade to PROFIsafe
–E cient programming and commissioning

To customise the safety application, adapt the settings of safety parameters. To configure via software, use the
VLT® Motion Control Tool MCT 10 safe plug-in.
Convenient PC-based MCT 10 user interface.
Easy integration
Fail-safe controllers, fail-safe I/O, and fail-safe drives permit the
implementation of safety requirements in every machine. The PROFIsafe device extends the advantages of functional safety to the next level of flexibility.
It enables extension from an isolated safety device to interconnecting and cooperating safety-related devices within a plant.
