Does Altivar 71/61 drive with Passive filter draw high input current during no load.


Passive filters are adjusted for nominal load. In case of no load or low load, reactive power (from passive filter capacitors) increases. That is why,Altivar 71/61 drive with Passive filter draws high input current during no load
 
A solution, to avoid this behavior, is to disconnect the passive filters by using contactors for passive filter.

Refer to attached scheme for controlling the filter via the drive according to the load.
