PRODUCT DESCRIPTION
2 Product Description
The COMBIVERT P6 series are drive controllers that have been developed for use as
pitch controllers in wind turbines. They are used to actively adjust the rotor blades of the
wind turbine, which therefore allows controlling the rotor speed and the turbine output
power.
As part of the safety system, the COMBIVERT P6 drive controllers can protect the wind
turbine from a dangerous overspeed or bring it to a standstill in case of a turbine fault by
quickly turning the rotor blades "out of the wind".
In order to be able to perform this safety function even in case of a power failure, energy
storage devices (rechargeable batteries or ultracapacitors) are connected to the P6 as
a backup supply.
The COMBIVERT meets the requirements of the Low-Voltage Directive. The harmo-
nized standards of the series
The COMBIVERT is a product of limited availability in accordance with
product may cause radio interference in residential areas. In this case the operator may
need to take corresponding measures.
The machine directive, EMC directive, Low Voltage Directive and other guidelines and
regulations must be observed depending on the version.
2.1 Specified application
The COMBIVERT is used exclusively for the control and regulation of three-phase mo-
tors or DC motors. It is intended for installation in wind turbines.
Technical data and information for connection conditions shall be taken from the type
plate and from the instruction manual and must be strictly observed.
The used semiconductors and components of the KEB Automation KG are developed
and dimensioned for the use in industrial products.
Restriction
If the product is used in machines, which work under exceptional conditions or if essen-
tial functions, life-supporting measures or an extraordinary safety step must be fulfilled,
the necessary reliability and security must be ensured by the machine builder.
2.1.1 Residual risks
Despite intended use, the drive controller can reach unexpected operating conditions
in case of error, with wrong parameterization, by faulty connection or unprofessional
interventions and repairs. This can be:
•
•
•
•
•
2.2 Unintended use
The operation of other electric consumers is prohibited and can lead to the destruction of
the unit. The operation of our products outside the indicated limit values of the technical
data leads to the loss of any liability claims.
