Configuring a product
The decentralized motor controls DMS 300 and
FCD 300 series are configured with a type code
string (
see also Ordering
):
DMS 330 P T4 P66 XX D0 Fxx Txx C0
FCD 3xx P T4 P66 R1 XX Dx Fxx Txx C0
Electrical voltage
DMS 300/FCD 300 are available for connection to
electrical voltage 3 phase 380-480 V.
Choice of motor starter
The motor starter DMS 300 covers the whole power
range from 0.18-3 HP (kW) in one unit.
Choice of adjustable frequency drive
The adjustable frequency drive must be chosen on
the basis of the present motor current at maximum
loading of the unit. The adjustable frequency drive
’
s
rated output current I
INV.
must be equal to or greater
than the required motor current.

Enclosure
DMS 300 / FCD 300 units are protected against
water and dust as standard.
See also the section entitled
Technical data
for further details.
■
Brake
FCD 300 is available with or without an integral
brake module. See also the section entitled
Brake
resistors
for ordering a brake resistor.
EB version including mechanical brake control/supply.
■
24 V external supply
Back up of control supply with 24 V DC is
available in EX and EB versions.
■
RFI filter
FCD 300 has an integral 1A RFI-filter. The integral
1A RFI filter complies with EMC standards EN
55011-1A. See the sections
Cable lengths
and
Cross section
for further details.
■
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 relatively high percentage of rectifier
load it is important to keep the harmonic currents at
a low level so as to avoid a transformer overload and
high cable temperature. For the purpose of ensuring
low harmonic currents, the FCD 300 units are fitted
with coils in their intermediate circuit as standard. This
reduces the input current I
RMS
by typically 40 %.
■
Display unit
On the FCD 300 unit there are 5 LEDs for voltage
(ON), warning, alarm, status and bus.
In addition, a plug for connecting an LCP control panel
is available as an option. The LCP control panel can be
installed up to 9 feet away from the variable frequency
drive, e.g. on a front panel, by means of a mounting kit.
All displays of data are via a 4-line alpha-numerical
display, which in normal operation is able to show
4 operating data items and 3 operation modes
continuously. During programming, all the information
required for quick, efficient parameter Setup of the
variable frequency drive is displayed. As a supplement
to the display, the LCP has three LEDs for voltage
(ON), warning (WARNING) and alarm (ALARM).
