■ Enclosure
All VLT 2800 units are supplied with IP 20
enclosure as standard.
This enclosure level is ideal for panel mount ing
in areas where a high degree of protection is
required; at the same time IP 20 enclosures
allow side-by-side installation with
out any need
for extra cooling equipment.
IP 20 units can be upgraded with IP 21 / top
coverand/orNEMA1byfittingatermin
al cover.
See ordering number for terminal cover under
Accessories for VLT 2800 .
In a ddition, VLT 2880-82 units are supplied with
Nema 1 enclosure as standard.
■ Brake
VLT 2800 is available with or without an integral
brake module. See also the section entitled Brake
resistors for ordering a
Brake resistor.
■ Wobble function
The wobble funct ion is used for winding applications
in the textile industries. All VLT 2800 frequency
converters are suppl
ied with a wobble function as a
standard feature. The frequency converter is able to
operate a m otor, which turns a grooved drum. During
winding, the gro
oved drum places the thread in the
correct posit ion on the bobbin, in a d iamond pattern.
For further information, see VLT 2800 Wobble
Instruction MI
50JXYY.
■ RFI filter
VLT 2800 is available with or without an integral
1A RFI-filter. The integral 1A RFI filter complies
with EMC standards EN 55011-1A.
With an integral RFI filter there is com p liance with EN
55011-1B with a max. 15-metre screened/armoured
motor cable on VLT 2803-2815 1 x 220-240 Volt.
VLT 2880-82 with integral 1B filter comply with
EMC standard EN 50011 - 1B
■ Harmonic filter
The harmonic currents do not affect power
consumption directly, but they increase the heat losses
in the installation (transformer, cables). That is why, in
a system with a rela tively high percentage of rectifier
load, it is important to keep the ha rmonic currents at
a low level so as to a void a transformer overload and
high cable temperature. For the purpose of ensuring
low harmonic currents, VLT 2822-2840 3 x 200-240
V and VLT 2805-2882 380-480 V are fitted with coils
in their intermediate circuit as standard. This reduces
the input current I
RMS
by typically 40 %.
Please note that 1 x 220-240 V units are not supplied
with coils in their intermediate circuit.
■ FC protocol
Danfoss frequency co nverters are able to fulfill
many different functions in a monitoring system.
The frequency converter can be integrated directly
in an overall surveillance system, which will
allow detailed process data to be transferred
via serial communication.
