The future of safety in now

What’s so special about Functional Safety?

Confidential | 7

Key words: Redundancy & Diagnostics

“The system will be able to handle a fault while maintaining the current safety level and

informing the user through self-diagnosis”

Current safety features

Safety

Safety today, more than ever, is and integral part of todays smart factory

How?

Functional Safety is necessary to allow todays technologies to become more efficient, flexible, autonomous & lean while maintain utmost safety

No need to stop the machines operation

No dependency on drive type

Safety function (SLT,SLS…) already approved

INDUSTRY 4.0

Relying on the servo drivefor critical safety functionsis a huge advantage for manufacturing.

Added Machine FunctionalityThrough innovative safety features

Simplified MachineReplace Safety Hardware for motion Software

Less Expensive Replace Power Components for Logic Level

Advanced Functional Safety over the Network:

Achieve More with Smart Safety

Less Hardware

Less Cost

Less Time to Market

Advantages

Doing all of that,

with this…. And much more

Advantages

Safety Level: SIL

SIL: Safety Integrity level (IEC 62061 \ IEC 61508)

A SIL is expressed as a target failure value for the probability of dangerous failure per hour of each safety related function

SIL3: reduction of 1,000 to 10,000 SIL4: reduction of 10,000 to 100,000

Safety Level: CAT & PL

CAT: Category of failure in safety (EN ISO 13849) What is the type of circuit architecture used to achieve

the safety performance level. CAT3, CAT4

PL: Performance level (EN ISO 13849) Probability of dangerous failure per hour Severity of harm Probability of occurrence PLd: >10-7, PLe: >10-8

Platinum Safety: SLSSLS: Safe Limited

Speed With Time Monitoring.

At activation, “t_SLS” counter is started and drive should decelerate*.

After “t_SLS”, Speed is Monitored within ±n_SLS.

Monitoring can optionally start t_L_SLS after speed is within ±n_SLS limits.

* Deceleration itself is not part of the Safety Function !

Platinum Safety: SS!SS1: Safe Stop 1, With

Time Monitoring. At activation, “t_SS1” counter is

started and drive should decelerate*.

After “t_SS1”, STO is engaged.

Platinum Safety: Sensors The following sensors are designed for the functional safety

Platinum Safety

Confidential | 31

Platinum Safety: Error Concept Monitoring errors:

The drive, upon request, monitors predefined threshold values according to the safety function.

If threshold fails a monitoring error is been activated

Diagnostics errors:

Safety components are periodically checked to guarantee that there is no failure along the path of the requested functions. If diagnostics fails (usually) a power up is

required

Safety Over EatherCAT

Confidential | 32

FSoE (Fail/Safe over EtherCAT) Advantages:

Single communication for both control and safety data

Pre-certified solution to simplify safety applications

Powerful diagnostic capabilities for safety functions

Seamless integration of the safety design in the machine design

FSoE allows transferring safety-critical control dataover the standard deterministic EtherCAT channel

Safety Over EtherCAT technology was developed according to IEC 61508, is TÜV certified, and standardized.
