2.1.4 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 integrator 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 faults and/or software errors in the sensors, control system, actuators, and
connections
– Response times of the control system and of the drive
– Operation and/or environmental conditions outside the speci󹪝cation
– Condensation/conductive contamination
– Parameterization, programming, cabling, and installation errors
– Use of wireless devices/mobile phones in the immediate vicinity of electronic components
– External in󹪞uences/damage
– X-ray, ionizing radiation and cosmic radiation
2. Unusually high temperatures inside and outside the components, including open 󹪞ames, as
well as emissions of light, noise, particles, gases, etc. due to fault conditions, e.g.:
– Component failure
– Software errors
– Operation and/or environmental conditions outside the speci󹪝cation
– External in󹪞uences/damage
– Short circuits or ground faults in the intermediate DC circuit of the converter
3. Hazardous shock voltages caused by, for example:
– Component failure
– In󹪞uence during electrostatic charging
– Induction of voltages in moving motors
– Operation and/or environmental conditions outside the speci󹪝cation
– Condensation/conductive contamination
– External in󹪞uences/damage
4. Electrical, magnetic and electromagnetic 󹪝elds 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
