- Fully digitized 3AC servo controller -

Main features


The new series digiSTAR is the improved successor of the digiVEC servo inverter.
The digiVEC is still available, but for new applications we recommend the digiSTAR.

             3AC 230V ... 400V +/-15%
             (Optional 460V +10%/-15%)
Output frequency:   0 Hz ... 800 Hz
Rated current:     4 A ... 48 A
Overload    1 s:  100 %
Overload  30 s:  50 %
Motors: AC-Asynchronous,
             AC-Synchronous, DC-Servo,
             DC-Spindle incl. field weakening
