High dynamics for demanding applications


Emotron VFX 2.0 AC drive optimizes the operation of your cranes, crushers, mills and mixers. Your process is protected from damage and downtime and you will benefit from reduced installation, energy and maintenance costs.

Efficient and protective starts and stops

Efficient and protective starts are ensured with Emotron VFX. 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 productivity and safety.

 

Optimized operation and full control

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

 

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 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.
