By looking at our ND11, the progress that has been made in automation technology becomes visible, as it is not possible to control today’s highly dynamic drives with this device. But regarding the many machines in which ND11 has been operating for many years, it can be said: they have grown older, yet they are still far from being shut down. That is why ND11 for DC servo motors is still being delivered to our customers. It is available in four versions, either as a compact device or as a 19" module.
