Selection of modules and accessories
Danfoss offers a wide range of modules and accesso-
ries for VLT 5000 Series.
Sine-wave filter module
The sine-wave filter reduces the voltage rise time (dU/
dt) and the ripple current (
Δ
I) to the motor, thereby
making current and voltage almost sinusoidal. The
acoustic motor noise is therefore reduced to a mini-
mum.
See also instructions MI.56.DX.51.
LCP control unit
Control unit with display and keypad for programming
VLT frequency converters. Available as an option for
IP 00 and IP 20 units.
Enclosure: IP 65.
Remote-mounting kits for LCP
The remote kit option makes it possible to move the
display from the frequency converter e.g. to the front
panel of an integrated cabinet.
Technical data
Enclosure:
IP 65 front
Max. cable length
between VLT and unit:
3 m
Communication std:
RS 422
Reference is also made to instructions MI.56.AX.51
(IP 20) and MI.56.GX.52 (IP 54).
IP 4x top cover
IP 4x top cover is an optional enclosure element avail-
able for IP 20 Compact units.
If an IP 4x top cover is used, an IP 20 unit is upgraded
to comply with enclosure IP 4x from the top. In practice,
this means that the unit complies with IP 40 on upper,
horizontal surfaces.
A top cover is available for the following Compact
units:
VLT type 5001-5006, 200-240 V
VLT type 5001-5011, 380-500 V
VLT type 5001-5011, 525-600 V
Terminal cover
Using a terminal cover, it is possible to field mount an
IP 20 unit, type VLT 5008-5052.
A terminal cover is available for the following compact
units:
VLT type 5008-5027, 200-240 V
VLT type 5016-5102, 380-500 V
VLT type 5016-5062, 525-600 V
Contactors
Danfoss also manufactures a complete range of con-
tactors.
Brake resistors
Brake resistors are used in applications where high
dynamics are needed or a high inertia load has to be
stopped. The brake resistor is used to remove the en-
ergy, see also Instructions MI.50.SX.YY and MI.
90.FX.YY.
Harmonic filter
Harmonic currents do not directly affect the electricity
consumption but has an impact on following condi-
tions:
Higher total current to be handled by the installations
-
Increases load on transformer (sometimes it
will require a larger transformer, particular at
retrofit)
-
Increases heat losses in transformer and in-
stallation
-
In some cases demands larger cables,
switches and fuses
Higher voltage distortion due to higher current
-
Increase risk for disturbing electronic equip-
ment connected to same grid
A high percentage of rectifier load from eg frequency
converters, will increase the harmonic current, which
must be reduced to avoid the above consequences.
Therefore the frequency converter has as standard,
built in DC coils reducing the total current with about
40% (compared to devices without any arrangement
for harmonic suppression), down to 40-45% ThiD.
In some cases there is a need for further suppression
(eg retrofit with frequency converters). For this pur-
pose Danfoss can offer two advanced harmonic filters
AHF05 and AHF10, bringing the harmonic current
down to around 5% and 10% respectively. For further
details see instruction MG.80.BX.YY.
