NXL

Variable Speed Drives

Description

Variable motor speed drives suitable for a wide range of voltage
and current loads. Convert fixed frequency and voltage from the
mains supply to variable frequency and voltage enabling motors to
be used with maximum efficiency resulting in significant energy
savings. The drive has a built-in PID control application that can be
adjusted from the control keypad.
NXL drives are suitable for mounting in a small space, using back,
side, or DIN rail mounting.
The drives are easily programmed and commissioned by using
the control keypad or PC tools software.

FUNCTIONALITY

The NXL range of variable speed drives provides both three phase to three phase (1 A to 61 A) and single phase to three phase
(2 A to 6A) units. Of particular use in the HVAC environment, they enable fans and motors to regulate delivery of air and water
in variable flow applications. Where flow rates may be reduced, motor energy can be significantly cut as the relationship between
flow rate and power follows a cube law hence reducing flow by 20% reduces power by 50%. The drives also enable saving in
installation costs; switchgear is eliminated, motor cables are reduced from 6 to 3 wires, power factor correction capacitors are
not required, size and cost of cabling and fuses is minimised (as starting current is kept within nominal value).
The sensorless flux vector control gives dynamic precision over most of the speed range. A drive is provided with built-in control
application, which can be set up from the control keypad. It has a slot for an optional I/O expansion board.

HARDWARE

The Trend NXL is an extremely slim, space-saving and
easy-to-use frequency converter for the power range of 0.37
to 30 kW. The installation is flexible and easy using the mounting
components shipped with the unit. Traditional back installation
and side installation, suitable for very limited space, are available,
as well as DIN rail mounting.

An optimal solution is available for most application needs. The
modular design allows the choice of only the functions and
features needed in a specific application. The control keypad is
fitted as standard. The NXOPTAA board (3 x digital inputs, 1 x
digital relay output, and 1 x digital open collector output) is fitted
as standard in the I/O expansion slot of the Ecodrives; it can be

fitted as an optional extra in the Microdrives. At the core of the
Easy programming and commissioning add to overall
user-friendliness. The default control I/O of the Trend NXL includes
the most common control inputs and outputs. For maximum
compatibility, the connector numbers correspond to those of the
Trend NX drives. Parameter setting is carried out in a familiar

NXL is sensorless vector control technology coupled with current

measurements of all three output phases. Fieldbus control using

RS485 Modbus is available as standard. The Trend NXL also

incorporates PID control as standard, enhanced with a host of

special features such as a sleep function.

Control Keypad: The control keypad is used for parameter
setting, reading status data, and giving control commands. It is
detachable and can be operated externally being connected via
a cable to the frequency converter. A PC can be connected and
used to control the frequency converter instead of the control
keypad. (A 1.5 m, 9 way D type male to female extension cable
is available, ACC/NXL/RS232PC. A door mounting kit including a
2m cable is available, NXLDRA.)

The Trend NXL control keypad features a seven-segment display
with seven indicators for the Run status (RUN, READY, STOP,
ALARM, FAULT) and three indicators for the control place
(I/O term/ Keypad/BusComm). The control information, i.e. the
number of menu, the displayed value and the numeric information
are presented with numeric symbols.

The frequency converter is operable through the seven
push-buttons of the control keypad. Furthermore, the buttons
serve the purposes of parameter setting and value monitoring.
