Definitions and Warnings
Residual risks of Power Drive Systems (PDS)
The components for the controller and drive of a Power Drive System (PDS) are
DANGER
authorized for industrial and commercial use in industrial networks. Their use in
public networks requires a different planning and/or additional measures.
It is only permissible to operate these components in enclosed housings or in
superordinate control cabinets and when all protective devices and protective
covers are used.
These components may only be handled by qualified and trained specialist
persons who are familiar with and observe all the safety instructions on the
components and in the relevant technical user documentation.
The machine manufacturer must take into account the following residual risks resulting from the
components for the controller and drive of a Power Drive System (PDS) when evaluating the
risk of his machine in accordance with the EC machinery guideline.
1. Undesired movements of driven machine components during commissioning, operation,
maintenance and repair, e.g. as a result of
• HW and/or SW errors in the sensors, controller, actuators and connection system
• Reaction times of the controller and the drive
• Operation and/or ambient conditions not compliant with the specification
• Errors in parameterization, programming, wiring and installation
• Use of radio units/mobile phones in the direct vicinity of the controller
• External influences/damage.
2. Extraordinary temperatures and emissions of light, noises, particles and gases, e.g. as a
result of
• Component failure
• Software errors
• Operation and/or ambient conditions not compliant with the specification
• External influences/damage.
3. Dangerous contact voltages, e.g. as a result of
• Component failure
• Influence upon electrostatic charging
• Induction of voltages in the case of moving motors
• Operation and/or ambient conditions not compliant with the specification
• Condensation/conductive contamination
• External influences/damage.
4. Operational electrical, magnetic and electromagnetic fields that may pose a risk to people
with a pacemaker, implants or metallic items if they are too close.
5. Release of pollutants and emissions if components are not operated or disposed of properly.
For additional information on the residual risks emanating from the components of the PDS,
please refer to the relevant chapters of the technical user documentation.
