3 Product Overview

3.1 Product Characteristics

The VACON® 1000 medium-voltage drive is an alternating current speed regulating device from Danfoss. The drive features include
excellent performance, easy and convenient operation, and a wide range of applications using IGBT power devices and complete digital
control.
High efficiency and low distortion
The used multi-pulse input rectification transformer technology efficiently lowers the content of the input side distortion current
l
to less than 5%. It meets the IEEE 519-1992 standard and the strict requirements of electric grids for distortion, and enhances the
power factor to more than 0.96 lagging.
With the used cell-cascaded multilevel technology, there is normally no need for an output filter, and the output voltage waveform
l
is similar to a sine-wave.
System efficiency >98.5% (at rated frequency, excluding transformer).
l
Tolerant to power disturbances and wide applicable scope
When the input voltage is as low as 70%, the system can still continue derated operation.
l
With automatic output voltage adjusting function, when the input voltage fluctuates between 90–110%, the output voltage can still
l
be kept steady. Thus, safe and steady operation of the motor is possible.
High reliability
SOA (Service-oriented architecture) design ensures that the system operates in a wide safe range:
l
Sufficient design margin makes sure that each device operates in the middle area of the safe operating area.
¢
Optimized thermal design ensures temperature margin for the devices.
¢
The DC-link capacitors are designed for long lifetime service.
¢
Redundant auxiliary control power.
l
The system provides a self-diagnosis function to show the position and type of failure and warn the user about the fault occurrence.
l
Automatic detection and warning function for cooling fan failure or excessive dust in the inlet air filter notifying the user to conduct
l
maintenance.
Production quality management, control of the process flow, and perfect test equipment and methods ensure the effective
l
implementation of each test item for devices, components, and units during the manufacturing process at Danfoss.
Site flexibility
The compact structure and high power density of VACON® 1000 can reduce the space requirements on site.
l
The electric connections between the cabinets use highly reliable connectors which are easy to install and maintain.
l
Easy-to-operate human-machine interface.
l
Sufficient communication interfaces, which can be professionally configured in accordance with the application requirements.
l
All PCBs are coated to avoid problems with pollution and corrosive environments.

3.2 Applications

VACON® 1000 is used for the speed control of square torque loads such as fans, pumps, and compressors, as well as for mills, crushers,
and conveyor belts that require constant torque operation over the entire speed range. Accurate speed and torque controls result in
better energy saving, improved process quality, and prolonged equipment lifetime. Various industries that require reliable and stable
operation can benefit from the high performance of VACON® 1000 .
Power generation: Coal mills, blower fans, and water pumps.
