Residual Risks Of Power Drive Systems - Siemens SINAMICS S 1PH7 Configuration Manual

Residual risks of power drive systems

When carrying out a risk assessment of the machine in accordance with the EU Machinery
Directive, the machine manufacturer 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
More extensive information concerning the residual risks associated with the PDS is
provided in the relevant chapters of the technical user documentation.

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
