AKD-N Installation | 7 Mechanical Installation
7.1 Important Notes
CAUTION
There is a danger of electrical shock by high EMC level which could res-
ult in injury, if the drive (or the motor) is not properly EMC-grounded.
CAUTION
AKD-N Drives may have hot surfaces during operation. The housing can
reach temperatures above 80°C. Risk of minor burns! Measure the tem-
perature, and wait until the housing has cooled down below 40°C before
touching it.
Ensure free space of minimum 50 mm to all sides of the drive.
Protect the drive from impermissible stresses. In particular, do not let any components
become bent or any insulation distances altered during transport and handling. Avoid contact
with electronic components and contacts.
The drive will switch itself off in case of overheating. Ensure that the mounting space
matches the requirements (
➜
p. 24).
Do not mount devices that produce magnetic fields directly beside the drive. Strong magnetic
fields can directly affect internal components. Install devices which produce magnetic field
with distance to the drives and/or shield the magnetic fields.
An optimized thermal strategy is mandatory for AKD-N performance. Observe the inform-
ation given in the
Decentralized System Projecting Guide and in chapter "Temperature Man-
agement" (

p. 44)
7.2 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, please 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:
l
AKD-N 3 A : 240 mm x 240 mm x 10 mm
l
AKD-N 6 A : 500 mm x 500 mm x 10 mm
For a rough overview the three level rating below may help.
1. Optimum cooling situation
Cold plate size definition fulfilled, no additional heat sink required
2. Medium cooling situation
Example: 65% cooling plate available
Use the optional small heat sink (40 mm height) to reach optimum situation
3. 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.
