1.4 Residual risks of power drive systems
When assessing the machine- or system-related risk in accordance with the respective local
regulations (e.g. EC Machinery Directive), the machine manufacturer or system installer
must take into account the following residual risks emanating from the control and drive
components of a drive system:
1.
Uncontrolled motion of the driven machine or system components during commissioning,
operation, maintenance and repair caused by, for example:
–
Hardware and/or software errors in the sensors, control system, actuators and cables
and connections
– Response times of the controller and drive
– Operation and/or environmental conditions outside the specification
– Condensation/conductive pollution
– Parameterization, programming, cabling, and installation errors
– Use of wireless devices/mobile phones in the immediate vicinity of electronic
components
– External influence/damage
– X-ray, ionizing radiation and cosmic radiation
2. Unusually high temperatures - including open flames - as well as the emission of light,
noise, particles, gases, etc. can occur inside and outside the components under fault
conditions caused by, for example:
–
Component malfunctions
– Software errors
– Operation and/or environmental conditions outside the specification
– External influence/damage
3. Hazardous shock voltages caused by, for example:
–
Component malfunctions
– Influence of electrostatic charging
– Induction of voltages in moving motors
– Operation and/or environmental conditions outside the specification
– Condensation/conductive pollution
– External influence/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 correctly
6. Influence of network-connected communication systems, e.g. ripple-control transmitters
or data communication via the network

relevant sections in the technical user documentation.
