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® 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.

nOPT-BL – Advanced safety with proximity­ switch and PROFIsafe

nOPT-BM – Advanced safety with HTL/TTL encoder and PROFIsafe

nOPT-BN – Advanced safety with SIN/COS encoder and PROFIsafe

Fieldbus profiles like PROFIsafe and PROFIdrive­ 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 infrastructure is optimally utilised, since no separate cabling is required.

Advanced safety functions

The VACON® Advanced Safety Option adds a total of nine additional safety functions to the VACON® NXP family.

Safe Stop functions

nSTO – Safe Torque Off

nSS1 – Safe Stop 1

nSS2 – Safe Stop 2

nSBC – Safe Brake Control

nSQS – Safe Quick Stop

Safe Speed functions

nSLS – Safely-limited Speed

nSSM – Safe Speed Monitor

nSSR – Safe Speed Range

nSMS – Safe Maximum Speed

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.
