1.4 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,
2. Exceptional temperatures as well as emissions of light, noise, particles, or gas caused by,
3. Hazardous shock voltages caused by, for example:
4. Electrical, magnetic and electromagnetic fields generated in operation that can pose a
5. Release of environmental pollutants or emissions as a result of improper operation of the

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
for example:
– Component malfunctions
– Software errors
– Operating and/or ambient conditions not within the scope of the specification
– External influences / damage
– 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
