The new edition of the high-precision motors offers three direct advantages in comparison to the predecessor series: Drive is provided by the high efficiency AR stepper motor-driver combination, which, thanks to its high efficiency, is characterised by enormous energy savings, thus providing clear cost advantages. In addition to the pulse inlet type, a version with an integrated controller is also available. In terms of the frame sizes, a type with a frame size of 85 mm has finally been added; an ideal supplement to the previous frame sizes of 60, 130 and 200 mm.
