1 Data Sheet Variable Speed Drives 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. 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.

3 Data Sheet FUNCTIONALITY The NX range of variable speed drives provides both three phase to three phase ( A to A) and single phase to three phase ( A to A) 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 0% reduces power by 50%. The drives also enable saving in installation costs; switchgear is eliminated, motor cables are reduced from to 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 is an extremely slim, space-saving and easy-to-use frequency converter for the power range of 0.7 to 0 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. Easy programming and commissioning add to overall userfriendliness. The default control I/O of the Trend includes the most common control inputs and outputs. For maximum compatibility, the connector numbers correspond to those of the Trend NX drives. setting is carried out in a familiar way, either via the control panel or by means of the PC tools for the. 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. An optional NXOPTAA board ( x digital inputs, x relay output, and x digital open collector output) can be fitted into the I/O expansion slot. At the core of the 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 also incorporates PID control as standard, enhanced with a host of special features such as a sleep function.

7 Data Sheet FIRMWARE Applications The Multicontrol Application for Vacon uses direct frequency reference from the analogue input as a default. However, a PID controller can be used e.g. in pump and fan applications, which offers versatile internal measuring and adjusting functions. This means that external devices are not necessary. When the drive is commissioned, the only visible parameter group is B (Basic parameters). The special parameters can be browsed and edited after changing the value of par.. ( conceal). The direct frequency reference can be used for the control without the PID controller and it can be selected from the analogue inputs, fieldbus, keypad, preset speeds or motor potentiometer. The PID controller reference can be selected from the analogue inputs, fieldbus, PID keypad reference or by enabling the PID keypad reference via digital input. The PID controller actual value can be selected from the analogue inputs, fieldbus or the actual values of the motor. PID controller can also be used when the frequency converter is controlled via fieldbus or the control keypad. Digital inputs DIN, DIN, (DIN4) and optional dig. inputs DIE, DIE, DIE are freely programmable. Internal and optional digital/relay and analogue outputs are freely programmable. Analogue input can be programmed as current input, voltage input or digital input DIN Additional functions: The PID controller can additionally be used from control places I/O, keypad and fieldbus Sleep function Actual value supervision function: fully programmable; off, warning, fault Programmable Start/Stop and Reverse signal logic Reference scaling Preset speeds Analogue input range selection, signal scaling, inversion and filtering Frequency limit supervision Programmable start and stop functions DC-brake at start and stop Prohibit frequency area Programmable U/f curve and U/f optimisation Adjustable switching frequency Autorestart function after fault Protections and supervisions (all fully programmable; off, warning, fault): Variable Speed Drives Data Sheet TA000 Issue /C /05/0 7

9 Data Sheet INSTALLATION The Trend drive must be installed in a vertical position. It can be mounted on a wall or in an enclosure using four screws or bolts. The cooling method for 000, 000, and 000C is convection type. Forced air cooling is used for 000C to 000C and 000 (C or C5) to 000(C or C5). The cooling airflow to the drive must not be blocked in any way, recirculation of air inside the enclosure should be avoided. Enough free space should be left above and below the frequency converter to ensure sufficient circulation and cooling.the following table gives the required clearance dimensions.
