EMC norm EN 55011 Class 1A and 1B
(with RFI filter).
Short circuit resistant
The VLT® 2800 will survive even short
circuit of motor cables and short
circuit of signal cables.
No derating at 40o
The VLT® 2800 will operate normally
(no need for derating) in environment
temperatures up to 40o C
Cold plate technology
Die-casted chassis
Various coded plugs
Hot pluggable display incl copy function.
SUB-D9 plug
Dry run detection
New features improve pump operation significantly and result in
improved energy savings as well as
pump protection in case of dry run
situations.
This new feature will protect the
pump in case the well runs dry, by
shutting down before damaging the
pump.
Important features are:
• Automatic or manual restart after
shut down
• Programmable restart delay up to
one hour.
• Shut down at low or no flow
• Operates in either open or closed
loop
Flexible mounting
VLT® 2800 is designed for flexible
mounting. A ventilated heatsink
allows for side by side mounting and
even horisontal mounting.
Quick Menu Button
Real side-by-side mounting
Integrated heat control in IGBT
User friendly
Enhanced sleep mode
Entering motor data in the quick
menu via the Local Control Panel is all
you need to be up and running.
When using pumps with flat pump
curves or when the suction pressure
varies, this feature provides excellent
control for shutting down the pump
at low flow, thus saving energy.

• Operates in closed loop
Single-phase
VLT® 2800 provides three-phase
power from a single-phase line outlet.
When a VLT® 2800 single-phase is
used, it’s just like getting three-phase
power from a standard power socket
– for pumps, fans, blowers etc. Now
up to 3.7 kW (5 HP).

Precise stop
Counter Precise Stop
Conventional units rely on a periodic
scan of the digital inputs, which
initiates the Stop command. This can
result in uneven delays while the
drive scans all the other parts of the
program taking up to perhaps 10 ms.
This is a disadvantage in typical
packaging applications.
After the start signal is received, the
VLT® 2800 operates until the user
programmed number of pulses is
seen at terminal 33. A Stop signal is
generated and the normal stop ramp
is used. The counter stop signal is
then re-armed and ready again for a
new start command. The pulse input
is designed to handle 24 V push-pull
pulses from an encoder with up to
1024 ppr. The maximum pulse rate is
67,600 Hz.
The wobble function is used for the
traverse function on a textile winder.
VLT 2800 operates a motor, which
turns a grooved drum. During
winding, the grooved drum places
the thread in the correct position on
the bobbin, in a diamond pattern.
If the traverse (grooved) drum was
operating at a constant speed, the
thread would tend to cross at the
same position for each pass, which
would give a very loose and less
compact winding on the bobbin.
For a conveyor operating at a speed
of 1 metre/second, that gives a
devia­­­­tion of ±10 mm. In the VLT®
2800, the Stop command is an
interrupt rather than part of the scan.
The repeating precision is improved.
The deviation is only ±1 mm in the
example used above.
