JANCD-MEW01-1 YASKAWA

Each time the drive 

generates a pulse to the motor using the input voltage 

a corresponding current draw occurs. Current is drawn 

from the line during each and every step of the variable 

three level output. 

Description:

The U1000 can be used for standard and 

regenerative applications with the unique 

advantage of direct AC-to-AC power 

conversion. This unique design offers the 

best choice for induction motors (IM) and 

permanent magnet motors (PM). Benefits include low 

input current harmonics with near unity power factor 

allowing for increased energy efficiency. The bidirectional

 switching technology allows for continuous 

motoring or continuous regeneration. This means that 

fewer parts are required, leading to higher machine 

reliability. Moreover, the U1000 can automatically 

switch into across-the-line operation through the 

drive, eliminating drive generated harmonics, drive 

losses, and motor noise.

Thanks to matrix technology, the 

U1000 can operate in full, continuous 

regeneration. It is your best drive for 

applications like conveyor, winder, 

escalator, lift or test bench, where 

braking energy needs to be considered. The 

AC-to-AC design does not require any braking 

resistor which takes space in the cabinet and 

creates additional heat during regeneration. 

Best of all, no parameter settings are needed to 

enable the U1000‘s regeneration. The U1000 can 

instantaneously and automatically switch from full 

motoring operation to full regenerative operation.
