The AKD-N is a De-centralised, Slim Line Servo Drive

The Kollmorgen de-centralised drive system consists of a central power supply and robust IP67 rated servo drives which are placed near to the motor. The system offers everything that is needed for the next generation of machine design and does away with anything that obstructs ease of use.

Kollmorgen AKD-NThe power supply, as well as safety features and fieldbus communication, is all combined in one single hybrid cable of only 11mm diameter. With regard to motor connections there is also only one cable needed for power, brake control and feedback. This straightforward approach results in massive cable economies in the machine of more than 80 percent!

The AKD-N is the new distributed servo drive generation from Kollmorgen which comprises of robust IP67-rated controllers which are positioned in close proximity to the motor and supplied by a central power module located in the switchgear cabinet. The 11mm diameter hybrid cable perfectly delivers the power as well as the fieldbus communication to the AKD-N. The controllers can therefore be operated directly in series via DC bus connection without an additional supply, covering power ratings of up to 4 kW. Safe Torque Off is integrated into the range as standard and can be deactivated on an individual or collective basis.

Outside the cabinet and hygienically packaged directly on the machine, the distributed AKD-N servo drives significantly reduce cabinet volumes and cable use. The improved thermal properties of the controllers positioned in parallel but physically separate, prevents the need for de-rating and in contrast to directly combined solutions they therefore offer 100% power. Furthermore, because integrated combinations types are predominantly focused on the motor and this actually restricts the optimum design of an application especially as these units are less flexible in terms of installation as a result of design features. Therefore as the AKD-N is able to connect to rotary servomotors as well as direct drive linear and rotary types, there is maximum scope for design where performance and power are concerned. Indeed the currently distributed servo technology can be combined with the centralised format as easily. Tertiary EtherCAT output and local STO are available as options

The advantages of reduced cabling with a high degree of flexibility through employment of a single standard cable for power and control across all feedback devices, means overall decreased hardware costs as well as greater cleaning permissability for machines. Typical fields of application of the new devices include packaging machines and production systems in the food and beverage industry.
