The new U1000 Matrix converter from Yaskawa represents the next generation in variable speed drive technology. It provides users with a reliable, low harmonic, fully regenerative solution without the addition of costly filters. The U1000 functions without a DC bus, using Yaskawa’s pioneering Matrix technology. This makes it unique compared to other variable speed drive technologies. The result is that the mains supply currents during operation are virtually sinusoidal, both in motor and regenerative operation.
Clean and efficient power usage
The Matrix technology reduces harmonics to a minimum, resulting in a total current harmonic distortion of less than 5%. Another benefit is the impressive near unity power factor, which means that losses in network components such as transformers, cables and lines are reduced and the efficiency of the system is increased further.
The U1000 also offers an integrated EMC filter. Unlike older technologies, components such as input or DC reactors and LC filters are no longer required. The result is a space requirement up to 50% less than conventional integrated solutions, with reduced harmonic distortion for regenerative loads. Eliminating external components not only simplifies the system structure but also makes the solution extremely simple to install for both new and retrofit requirements. Fewer system components mean improved system reliability and efficiency.
Integrated energy recovery
As the U1000 operates without a DC bus, it automatically has built-in energy recovery capability. The recovery function means that excessive braking energy can be re-used elsewhere on the network, directly reducing the energy requirements of the system. As a result of the inherent regenerative functionality, resistors and choppers are no longer required, resulting in less ventilation or cooling requirement compared to conventional systems.
Safety
The U1000 features a built-in SIL3 STO input and therefore aids the simple implementation of machine safety requirements. User installable and configurable option boards are available for all common fieldbuses and closed loop installations, allowing easy integration into new and existing systems. Varispeed has been the local agent for Yaskawa since 1992 and is also the only authorised drives repair partner for Yaskawa Europe for the southern African region. Stockholding of new units and spare parts results in competitive turnaround times, with service to match.
