General residual risks for PDS (Power Drive Systems)

Danger
!
The control and drive components of a power drive system (PDS) are approved
for industrial and commercial use in industrial line supplies. Their use in public line
supplies (public grids) requires a different configuration and/or additional
measures.
These components may only be operated in closed housings or in higher--level
control cabinets and when all of the protective devices and protective covers are
used.
These components may only be handled by qualified and trained technical
personnel who are knowledgeable and observe all of the safety information and
instructions on the components and in the associated technical user
documentation.
When carrying out a risk assessment of the machine in accordance with the EC
machinery directive, the machine manufacturer must consider the following
residual risks associated with the control and drive components of a Power Drive
System.
1. Unintentional movements of driven machine components during
commissioning, operation, maintenance, and repairs caused by, for example:
S Hardware and/or software errors in the sensors, control system, actuators
and connection systems
S Response times of the controller and drive
S Operation and/or environmental conditions outside the specification
S Parameterization, programming, cabling, and installation errors
S Use of radio devices / cellular phones in the immediate vicinity of the control
system
S External influences / damage
2. Exceptional temperatures as well as emissions of light, noise, particles, or gas
caused by, for example:
S Component malfunctions
S Software errors
S Operation and/or environmental conditions outside the specification
S External influences / damage
