Frequency inverters
vector frequency inverters
Application
With their sensorless vector control, the DV51 frequency inverters offer excellent
torque levels for three-phase motors with cage rotors. They are especially suitable
for demanding applications in which maximum torque and smooth running are
required at the lower speed range.
The assigned performance range for four-pole three-phase asynchronous motors
ranges from:
• 0.25 to 2.2 kW with single-phase power supply (230 V)
• 0.25 to 7.5 kW with three-phase power supply (230 V)
• 0.37 to 7.5 kW with three-phase power supply (400 V)
The vector frequency inverters DV51 can be used as a stand-alone drive or
incorporated in automation systems. The adaptable modules allow flexible
communication. With the sensorless vector control, applications in the plastics and
metal processing, textile, paper and printing industries and in crane and lift
installations are possible.

Documentation
• Each vector frequency inverter DV51 is supplied with an installation instruction
(AWA) and a CD.
• The installation instruction contains a short description with illustrations and
information about correct handling, installation and electrical connection of the
device. The information supplied is printed in seven languages (English,
Chinese, French, German, Italian, Russian, and Spanish).
• The CD contains a detailed manual (at least English, German) and configuration
software with help text.
• Documentation and parameterization software are also available for download
from the Internet:www.moeller.net/support
Note:
The software on the CD can be run on PCs with the current Windows operating
systems (from 98 to XP). For connecting a PC (RS 232) to a vector frequency inverter
DV51, you will need the connection cable DEX-CBL-2M0-PC (with integrated
interface converter).
