1.5 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. Unintentional movements of driven machine or system components during
commissioning, operation, maintenance, and repairs caused by, for example,
Hardware and/or software errors in the sensors, control system, actuators, and cables
and connections
Response times of the control system and of the drive
Operation and/or environmental conditions outside the specification
Condensation/conductive contamination
Parameterization, programming, cabling, and installation errors
Use of wireless devices/mobile phones in the immediate vicinity of electronic
components
External influences/damage
X-ray, ionizing radiation and cosmic radiation
2. Unusually high temperatures, including open flames, as well as emissions of light, noise,
particles, gases, etc., can occur inside and outside the components under fault conditions
caused by, for example:
Component failure
Software errors
Operation and/or environmental conditions outside the specification
External influences/damage
3. Hazardous shock voltages caused by, for example:
Component failure
Influence during electrostatic charging
Induction of voltages in moving motors
Operation and/or environmental conditions outside 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 correctly
6. Influence of network-connected communication systems, e.g. ripple-control transmitters
or data communication via the network
For more information about the residual risks of the drive system components, see the
relevant sections in the technical user documentation.
