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
– 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
