VFX Variable Frequency Drive

The VFX uses Direct Torque Control technology, which is an ideal cost and technical alternative to Servo and DC systems.

VFX features unique protection for the driven equipment. Many of today's budget VFDs are supplied in plastic enclosures that are subsequently required to be installed inside another NEMA rated panel. The VFX is offered in both IP20/21 (NEMA 1) and IP54 (NEMA 12) configurations. The NEMA 12 model offers the customer the opportunity to significantly reduce installation costs.

Efficient and Protective Starts and Stops

Efficient and protective starts are ensured with 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 distrubances 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 preventative action.

User-friendly and Reliable Operation

Operation paratmeters 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 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 - 250A units are IP54 (NEMA 12) classified. The robust all metal construction can be installed close to the application, which saves the cost of cabinets and long motor cables.

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 easily accessible mechanical parts and foldout power modules.
