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

Soft starts and stops protect your equipment. Reduced start currents result in smaller fuses, cables and energy bills. Controlled stops eliminate the risk of water hammer and other costly damage.

A built-in shaft power 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 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 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 virtual connection of logical functions, comparators and timers means no cables or external I/Os are required.

Cost-efficient and flexible installation

The compact standalone 2.5-250 A units are IP54 classified. The robust steel construction can be installed close to the application, which saves the cost of cabinets and long motor cables. The 300-1,500 A units can be mounted in compact Emotron-designed IP54 cabinets.

Simplified maintenance

Should a process problem occur a full status report will be generated. You can quickly identify the cause and take corrective measures. Maintenance is simplified thanks to a minimum of easy accessible mechanical parts and fold-out power modules.

Main features


• Robust and certified IP54 metal construction as standard offers
cost-efficient installation close to the application.
• All drive sizes are delivered with built-in Category C3 EMC-filter as
standard. C3 requirements are fullfilled with 80 m motor cable.
• Soft starts minimize start currents and linear stops prevent water
hammer.
• One Emotron FDU can control up to seven units without external control
systems.
• Energy saving function pauses the motor when it is not required to run to
maintain pressure.
• Efficiency is increased by setting the pump to run at full speed at certain
intervals to rinse out sludge.
• Speed controlled fans assures less noise, a more even drive temperature
and higher efficiency.
• Module fuses included as standard for sizes 300 - 3750 A (480 V) and
210 - 3000 A (690 V).
• Operation parameters can be set in your process units, for example
m3/min. and bar.
• Removable control panel with own memory means it is easy to transfer or
copy settings.
