Residual risks of power drive systems
When carrying out a risk assessment of the machine/plant in accordance with the EU
Machinery Directive, the machine manufacturer/plant operator must consider the following
residual risks associated with the control and drive components of a power drive system
(PDS).
1. Unintentional movements of driven machine components during commissioning,
operation, maintenance, and repairs caused by, for example:
Hardware defects and/or software errors in the sensors, controllers, actuators, and
connection technology
Response times of the controller and drive
Operating and/or ambient conditions not within the scope of the specification
Parameterization, programming, cabling, and installation errors
Use of radio devices / cellular phones in the immediate vicinity of the controller
External influences / damage
2. Exceptional temperatures as well as emissions of light, noise, particles, or gas caused by,
for example:
Component malfunctions
Software errors
Operating and/or ambient conditions not within the scope of the specification
External influences / damage
3. Hazardous shock voltages caused by, for example:
Component malfunctions
Influence of electrostatic charging
Induction of voltages in moving motors
Operating and/or ambient conditions not within the scope of the specification
Condensation / conductive contamination
External influences / damage
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
risk to people with a pacemaker, implants or metal replacement joints, etc. if they are too
close.
5. Release of environmental pollutants or emissions as a result of improper operation of the
system and/or failure to dispose of components safely and corre
ctly.
For more information about residual risks of the Power Drive System components, see the
relevant chapters in the technical user documentation.
