FR-A842-P Parallel Drives for Large Capacity Motors
Using all new technology to seamlessly synchronize two or three sets of inverter sections, the FR-A842-P parallel configuration is a unique solution for controlling large capacity motors up to 1800 horsepower. The FR-A842-P inverter sections are fed by converters in a common DC bus configuration (FR-CC2-P) and utilize balance reactors (FR-POL-H) to slow the rate of current rise on the output side of the drives. Ideal for large pumping systems and artificial lift applications, the FR-A842-P parallel configuration can offer high levels of motor control and performance while being a cost effective alternative to many medium voltage systems.
Intelligent Energy Optimization
As a result of the enhanced optimum excitation control in Mitsubishi Electric variable frequency drives, over current is no longer generated during steep acceleration/deceleration even without limiting the amount of voltage compensation during these operations which ultimately provides improved energy savings.
Specifications & Configuration
In parallel configurations, the capacity of the drives must be the same series in the system. Drive capacities cannot be mixed.
