Secure the flow and save energy
Emotron FDU 2.0 AC drive optimizes the operation of your pumps, fans, compressors and blowers. Your process is protected from damage and downtime, and you will benefit from reduced installation, energy and maintenance costs.
Protection from damage and downtime
A built-in load monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. Early warnings and safety stops for over- and underloads allow preventive action.
Energy savings and optimized operation
Emotron FDU regulates flow and pressure by continuously adapting motor speed. No energy wasted and no unnecessary equipment wear. A sleep function further reduces energy consumption by pausing the motor when it is not needed to be run. An automatic pump rinsing function increases efficiency.
Multiple pump or compressor control is a reliable and cost-efficient method of keeping a constant flow or pressure despite varying demands. Emotron FDU controls up to seven drives.
User-friendly and reliable operation
Operation parameters can be set in your own process units – m3/min, bar, Pascal, Celsius etc. – making monitoring easier and more reliable. The removable control panel has a copy function for transferring settings to other Emotron FDU units. You can switch between local and remote control by the push of a key on the control panel. The built- in programmable logical functions, comparators and timers means that external PLC or relays in many cases can be avoided.
Available in IP20/21 and IP54 versions
Emotron FDU is available in IP20/21and IP54 versions. The robust steel construction in IP54 version means that you can install your AC drive close to the application, which saves the cost of cabinets and long motor cables.The 300-1,500 A units (IP20 modules) is also available in compact CG-designed IP54 cabinets. IP20/21 series 25-244 A are optimised for mounting in control cabinets (IP20) or on electrical room wall (IP21). Robust and compact design, easy access to power terminals. Extended temperature range up to 55 °C.
Should a process or drive problem occur a full status report will be generated for each event in fault logger. You can quickly identify the cause and take corrective measures. Maintenance is simplified thanks to a minimum of easy accessible mechanical parts and by using fold-out power modules in bigger powers.
Options add functionality
A number of options let you customize the Emotron FDU 2.0 functionality and fully utilize the product according to your needs. Four different options can be combined.
Multiple pump or compressor control
Up to three I/O boards can be connected. This opens for multiple control of up to seven pumps or compressors without PLCs or other equipment.
Communication options include fieldbus communication via Profibus and DeviceNet, Industrial Ethernet communication via Modbus/TCP, EtherCAT and Profinet, and serial communication via RS232 or RS485 with Modbus RTU.
PTC and PT100 sensors can be connected to control motor temperature and give process feedback without using a transmitter.
This option board offers protection from unexpected start during mechanical maintenance, in accordance to the EN954-1 Category 3 standard. No contactor is required.
Units from 90 A can be provided with liquid cooling. This allows you to reduce operating and maintenance costs, and the cabinet can have a protection class higher than IP54.
A 1st environment category 2 EMC filter is available as a factory-mounted option.
Reduced harmonic distortions
A 12-pulse rectifier offers a cost-efficient reduction of harmonic current distortions. It reduces power losses in equipment such as transformers and conductors, and eliminates the need to over-dimension these components.
Makes it possible to supply the control circuits via an external 24 V AC/DC supply to maintain communication and set up the system when 3-phase mains is not connected. Provides communication backup if 3-phase main power supply fails.
IP21 Top cover
A top cover drip protection available for IP 20 units 11-132 kW if units are wall mounted in electrical room.
