■ Why choose Danfoss?
Danfoss manufactured the world's first mass-pro-
duced frequency converter back in 1968. We have
set the standard for quality drives ever since. That
is why our VLT frequency converters are today sold
and serviced in more than 100 countries covering
six continents.
With the new VLT 5000 Series, we are introducing
V V C
PLUS
. This is our new Sensorless Vector Drive
System for torque and speed control of induction
motors.
If compared with a standard voltage/frequency
ratio control, V V C
PLUS
offers improved dynamics
and stability, both when the speed reference and
the load torque are changed. In addition, we have
implemented a fully digitalised protection concept,
which ensures reliable operation, even under the
worst possible operating conditions. Naturally, the
VLT 5000 Series also offers full protection against
short-circuiting, earthing fault and overload.
Danfoss drives with the V V C
PLUS
control system
tolerate shock loads throughout their speed range
and react swiftly to changes in reference.
However, it must also be easy to reach this perfor-
mance. Danfoss is convinced that high-technology
drives can be made user-friendly. The VLT 5000
Series proves us right. In order to make program-
ming simple and easy-to-grasp, we have divided
the parameters into different groups. The Quick
menu guides users quickly through the program-
ming of the few parameters that must be set to get
started. The control panel is detachable. It features
a four-line alpha numeric display, enabling four
measurements to be displayed at the same time.
Via the detachable control panel, the programmed
settings can be copied from one VLT to the next.
This means that there is no time to be spent on
programming when changing drives or integrating
an extra drive in the installation.
The entire programming process is easier than ever
before. The VLT 5000 Series makes most adjust-
ments automatically.
If you have any questions concerning VLT fre-
quency converters, please call us. We have drive
specialists all over the world ready to advise you
on applications, programming, training and service.
