9300 vector – flexibility from design

The 9300 vector is a vector-controlled frequency inverter, that is best suited for demanding applications as for example filling plants, dosing and feed systems, as well as winding drives. Excellent drive behaviour - even without speed feedback - and undreamt- of possibilities for solving control tasks are only a few outstanding features provided by this frequency inverter.

Function blocks integrated into the 9300 vector software enable the 9300 vector to carry out control functions in addition to its drive task, similar to a PLC.
