VACON® Advanced Safety Options
Improve flexibility with integrated safety

The VACON® Advanced Safety
Options operate the safety functions
of an AC drive via the PROFIsafe
fieldbus or I/O control. They improve
flexibility by connecting safety de­vices within a plant.

The Advanced Safety Options are 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 or with I/O inputs. These safety
functions are implemented and tested
according to:

- EN 61800-5-2

- IEC 61508

- EN ISO 13849-1

- IEC 61511-1

- EN 62061

Advanced Functional Safety
with VACON® NXP

The VACON® Advanced Safety Options
expand the capabilities of the VACON®

Advanced safety functions

The VACON® Advanced Safety Option
adds a total of nine additional safety

functions to the VACON® NXP family.
NXP air and liquid cooled AC drives
by integrating nine advanced safety
functions into the AC drives including
both safe speed functions as well as a
PROFIsafe interface.

n OPT-BL – Advanced safety with

Safe Stop functions

n STO – Safe Torque Off

n SS1 – Safe Stop 1

n SS2 – Safe Stop 2

n SBC – Safe Brake Control

n SQS – Safe Quick Stop

proximity switch and PROFIsafe

n OPT-BM – Advanced safety with

HTL/TTL encoder and PROFIsafe

n OPT-BN – Advanced safety with

SIN/COS encoder and PROFIsafe

Safe Speed functions

n SLS – Safely-limited Speed

n SSM – Safe Speed Monitor

n SSR – Safe Speed Range

n SMS – Safe Maximum Speed

Fieldbus profiles like PROFIsafe and
PROFI drive are elements of the
PROFIBUS and PROFINET fieldbus
protocols. This permits the transmission
of standard and safety-related data on
a single bus cable. The existing network

inside the AC drive
– Reduced wiring and components
– Simple selection, configuration, project

planning, and installation
– Easy to configure via VACON® Safe

– 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

– Increased plant availability possible by

formation of safe I/O groups
– High level of flexibility when expanding plants

– Drives already running on PROFINET or

PROFIBUS are easy to upgrade to PROFIsafe
– Closed-loop control, without additional encoder

board, possible when installed in slot C

– Efficient programming and commissioning

Easy configuration

To customize the safety application,
adapt the settings of safety parameters.
To configure via software, use the
VACON® Safe PC tool.

Convenient PC-based VACON® Safe 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.
