Protection from damage and downtime

Smooth 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 load monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. These early warnings and safety stops for over- and underloads allow preventive action.

Energy savings and optimised operation

Emotron FDU 2.0 AC Drive regulates flow and pressure by continuously adapting motor speed. Therer is no wasted energy and no unnecessary wear on equipment. A sleep function further reduces energy consumption by pausing the motor when it is not. An automatic pump rinsing function also 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 with the push of a button on the control panel. The built- in programmable logical functions, comparators and timers means that, in many cases, external PLC or relays can be avoided.

Efficient and protective starts and stops

Emotron VFX 2.0 AC Drive ensures efficient and protective starts. Reduced start currents result in smaller fuses, cables – and energy bills. Torque can be boosted to overcome initial peak loads. Integrated vector braking ensures quick and controlled stops, increasing not only productivity but safety as well.

Optimised operation and full control

The direct torque control reacts extremely quickly to eliminate disturbances due to abrupt load changes. 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.

User-friendly and reliable operation

Operation parameters can be set in your own process units – m/sec, tons/hour, cycles/min etc. – making monitoring easier and more reliable. The removable control panel has a copy function for transferring settings to other Emotron VFX units. You can switch between local and remote control by the push of a button on the control panel. The built- in programmable logical functions, comparators and timers mean that, in many cases, external PLC or relays can be avoided.

Available in IP20/21 and IP54 versions

Emotron VFX 2.0 AC Drive is available in IP20/21and IP54 versions. The robust metal construction in IP54 version allows you to install your AC drive close to the application, which saves the cost of cabinets and long motor cables. The 300-3,000 A units (IP20 modules) are also available in compact CG-designed IP54 or IP23 cabinets. IP20/21 series 2.5-365 A are optimised for mounting in control cabinets (IP20) or on electrical room walls (IP21, 25-365A). Emotron VFX has a robust and compact design, with easy access to power terminals and an extended temperature range up to 55 °C.

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.

Options add functionality

A number of options let you customise the functionality of the Emotron VFX and fully utilise the product according to your needs. Up to four different options can be combined.

Crane control

A crane I/O expansion board offers efficient hoist and travel drive, and a safety system which activates the mechanical brakes should dangerous loads be detected. It also provides a load-dependant, field weakening function for hoist drives.

Shorter braking time

For short braking time or continuous braking, chopper is available as a factory-installed option. It is used in combination with brake resistors and is dimensioned according to the specific application demand.

Communication

Communication options include fieldbus communication via Profibus and DeviceNet, CANopen, Industrial Ethernet communication via Modbus/TCP, EtherCAT and Profinet, and serial communication via RS232 or RS485 using Modbus RTU protocol.

Motor protection

PTC and PT100 sensors can be connected to a monitor and protect motor temperature and give process feedback without using a transmitter.
