Siemens SIMOTICS S-1FK2 Service Manual

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. 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 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, including open 󹪞ames, 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 speci󹪝cation
– External in󹪞uences/damage
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
6. In󹪞uence 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.
