Increased occupational safety and reduced idling times

System controls that monitor the production process instead of switching it off can be installed in the system in accordance with the EC Machinery Directive 2006/42/EC and EN ISO 13849-1 standard, which are intended to minimize the risk posed to people by technical equipment. The control systems applied must satisfy the relevant requirements regarding safety and performance level.

Not only is the concept of “functional safety” significant for employee safety, but it can also significantly increase the productivity of the machines and systems. This is why SEW‑EURODRIVE is investing in flexible solutions with safetyDRIVE. Flexibility is key: the modular safety technology components or the safety technology integrated directly into the drive technology are individually selected and adapted according to the application and task.

CE conformity in accordance with the Machinery Directive

Machinery Directive 2006/42/EC for increased machine and plant safety

CE Conformity: Machinery Directive 2006/42/EC
CE Conformity: Machinery Directive 2006/42/EC

On December 29, 2009, the new Machinery Directive 2006/42/EC came into force, stipulating important new conditions for machine and plant engineering. The harmonized standards for Machinery Directive 2006/42/EC include the standards EN ISO 13849-1+2 and EN 62061, which govern the functional safety of electrical/electronic/programmable electronic safety-related systems. They also include the standard IEC 61508 for functional safety management that stipulates the necessary requirements for processes, responsibilities and organizational principles.

The CE marking is the external indication for the compliance of a product with the requirements of the Machinery Directive.

With the CE marking, the responsible party declares that:

  • The product complies with all of the applicable European Community provisions
  • The prescribed conformity evaluation procedures have been carried out

The CE marking enables the unrestricted movement of goods within the European Economic Area.

safetyDRIVE: Drive Safety Functions

Benefit from our drive safety functions from the safetyDRIVE program

SS1 – Safe Stop 1
SS1 – Safe Stop 1

SS1 – Safe Stop 1

This safety function

  • triggers the controlled deceleration of the drive; the power supply to the motor is then safely disconnected
  • prevents dangerous movement of the drive when it is at a standstill
  • corresponds to stop category 1 according to IEC 60204-1
SS2 – Safe Stop 2
SS2 – Safe Stop 2

SS2 – Safe Stop 2

This safety function

  • triggers the controlled deceleration of the drive; safe standstill monitoring is then initiated
  • ensures the complete availability of the drive control functions (motor stays energized)
  • corresponds to stop category 2 according to IEC 60204-1
SBC – Safe Brake Control
SBC – Safe Brake Control

SBC – Safe Brake Control

This safety function

  • disconnects the power supply to the brake
  • prevents the brake from releasing
SDI – Safe Direction
SDI – Safe Direction

SDI – Safe Direction

This safety function

  • allows the drive to move in one defined direction of rotation only
  • signals an error if the defined direction of rotation is violated, and safely switches off the drive if required
SLS – Safely Limited Speed
SLS – Safely Limited Speed

SLS – Safely Limited Speed

This safety function

  • monitors the speed and ensures that the defined velocity limit is not exceeded
  • signals an error if the speed threshold is exceeded, and safely switches off the drive if required
SOS – Safe Operating Stop
SOS – Safe Operating Stop

SOS – Safe Operating Stop

This safety function

  • monitors the stop position that has been reached and prevents the drive from leaving the stop position
  • ensures the complete availability of the drive control functions
  • signals an error if the drive leaves the stop position, and safely switches it off if required
SLA – Safely Limited Acceleration
SLA – Safely Limited Acceleration

SLA – Safely Limited Acceleration

This safety function

  • monitors the speed and ensures that the defined acceleration is not exceeded
  • signals an error if the speed threshold is exceeded, and safely switches off the drive if required
SLI – Safely Limited Increment

Evaluation of safety-related machine controllers according to DIN EN ISO 13849

The SISTEMA software wizard assists with evaluating the safety of controllers and drive systems with respect to DIN EN ISO 13849-1. The windows tool simulates the structure of the safety-related parts of a controller based on the so-called intended architectures and calculates reliability values on several detail levels including the achieved performance level (PL).

The latest version of the SISTEMA software wizard is available on the website of the Institute for Occupational Safety and Health of the German Social Accident Insurance: www.dguv.de

SEW-EURODRIVE offers a component library for the SISTEMA software wizard. This library includes the respective MTTF, B10d or PFH values for the components used. The library can be used in SISTEMA version 1.1.6. or later.
