Plant and Machine Safety

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

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

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

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

This safety function

disconnects the power supply to the brake
prevents the brake from releasing

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

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

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

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

This safety function

facilitates a safe jog mode
signals an error if the jog range is violated, and safely switches off the drive if required

SBA – Safe Brake Actuation

This safety function

brings a drive movement to a safe standstill mechanically. This procedure is not the standard braking procedure, but rather the braking procedure for emergencies.

SBH – Safe Brake Hold

This safety function

holds the current position mechanically when it is activated. The drive is already at a standstill when the function is activated.

SAR – Safe Acceleration Range

This safety function

prevents the drive acceleration from exceeding a specified range
deactivates the safety function when the permitted acceleration range is exceeded or undercut and triggers an error message

SLP – Safely Limited Position

This safety function

monitors the drive to ensure that it does not exceed the defined limits
signals an error if the limits are exceeded, and safely switches off the drive if required

SSM – Safe Speed Monitor

This safety function

facilitates speed monitoring
signals the status with no error response

SCA – Safe CAM

This safety function

facilitates the monitoring of a position range
signals the status with no error response

SSR – Safe Speed Range

This safety function

prevents the drive speed from exceeding a specified range
deactivates the safety function when the permitted speed range is exceeded or undercut and triggers an error message
