ND21 is a digital servo converter for brushless servo motors available in a 2,5 kW, 5 kW and 10 kW version. It weighs only 1,150 grams and has a size of 229 x 100 x 71 mm.
Nothing extraordinary from today’s perspective. But in 1992, ND21 was a sensation! It contained in a single device all functions necessary to control a motor, and it thereby offered entirely new opportunities.
We do not produce the ND21 anymore, but since then this all-in-one philosophy has been consequently pursued by us – regarding the subsequent NOVODRIVE ND30 series and, of course, our brand-new NOVODRIVE ND40 series.
