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.
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.
Quick commissioning
Parameter configuration is fully
integrated into the VLT® Motion
Control Tool MCT 10 and enables
simple start-up and easy maintenance.
Visual instructions in MCT 10 ensure
both fault-free wiring and that safety
parameters are correctly transferred
from the PC to the drive.
The software also offers easy diagnosis
and a dynamic commissioning report
which can be used for supplying
certification documentation necessary
for safety acceptance tests.
module is certified according to ISO
13849-1 up to PL d as well as IEC 61508/
IEC 62061 up to SIL 2 and provides
SS1 and SLS (SMS) functionality. The
option can be used in low and high
demand applications. SS1 offers ramp
and time based functionality. SLS can
be configured both with and without
ramp down on activation.

The VLT® Safety Option MCB 152
operates the safety functions of an
AC drive via the PROFIsafe fieldbus in
combination with the VLT® PROFINET
MCA 120 fieldbus option. Central
and decentral drives located at
different machinery cells can easily
be interconnected with the PROFIsafe
