Область применения

• The frequency converter controls the speed of asynchronous motors steplessly
• The modular, service-friendly concept of the frequency converter is ideally suited to manufacturing processes with high plant standstill costs
• Optimal solutions can be created using several frequency converters combined in one distributed station when drives are operated in the same area or for the same purposes.
• The frequency converter handles frequency control for simple applications as well as vector control for more complex drive tasks. It also handles the optimal control of a motor brake, if used.
• The converter also supports torque control, for example, for applications with mechanically coupled drives.
• The advantages of line-commutated power regeneration are primarily evident in continuous regenerative operation. Examples include unwinding units, lowering of loads, or dynamic braking of large centrifugal masses.
• The integral safety functions significantly reduce the overhead for drive solutions in plant sections where there is a hazard potential. Additional savings can be made thanks to sensorless speed monitoring of standard asynchronous motors.
