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.

(Safe Torque Off )
– 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

– Effi 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.
