efficient and protective starts and stops

Efficient and protective starts are ensured with Emotron VFX. Reduced start currents, thanks to direct torque control 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 load monitor and a unique Load Curve Protection function protect your process by immediately detecting any situation that could cause inefficiency or damage. Early warning and safety stops for over- and underloads allow preventative action.

 

cost-effective and flexible installation

The compact standalone 2.5 - 250A units are NEMA 12 (IP54) classified. The robust, all-metal construction can be installed close to the application, which eliminates the cost of cabinets and long motor cables.

 
 

Simplified maintenance

Should a process problem occur, a full status report will be generated for each event in the fault logger. You can quickly identify the cause and take corrective measures. Maintenance is simplified thanks to a small number of easily accessible mechanical parts and by using fold-out modules in larger units.

 

User-friendly and reliable operation

Operation parameters can be set in your own process unit - 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 VFX units. You can switch between local and remote control with the push of a single key on the control panel. The built-in programmable logical functions, comparators, and timers, means that external PLCs or relays can be avoided in many cases.

Maximum Power Under Full Control

In 1977, Emotron was the first company to introduce an AC Drive based on Pulse Width Modulation (PWM). Further developments led to one of the first market launches of AC Drives with direct torque control in 1998. The Emotron technology has an extremely fast response time, since actual and required torque is compared 40,000 times per second.

Emotron AC Drives can provide the highest possible torque per ampre from a normal industrial motor, offering the option of controlling a motor without a rotor sensor while still maintaining control of torque and speed.
