8.2 Temperature Management
The possible continuous output current and output power depends on the cooling situation for
the AKD-N. For a detailed calculation of temperature behavior of the decentralized drive sys-
tem based on the special machinery architecture, contact the Kollmorgen customer support.
Optimum cooling situation to reach rated power:
Cold plate requirements with 40°C surrounding temperature at 680 VDC supply voltage:
AKD-N 03 A : cold plate 350 mm x 350 mm x 10 mm
AKD-N 06 A : cold plate 500 mm x 500 mm x 10 mm
AKD-N 12 A : heat sink 480 mm x 400 mm x 84 mm, 31 fins
For a rough overview the three level rating below may help.
1. Optimum cooling situation: Cold plate / heat sinksize definition fulfilled,
no additional heat sink required
2. Bad cooling situation: Example: 50% cooling plate available
Use the optional big heat sink (50 mm height) to reach optimum situation.
The heat sink variants are described in the regional accessories manual.
