10.1 Notes on installing the control cabinet
All ECODRIVE drive components -- with the exception of the motors --
are designed to be installed into a control cabinet. When planning the
control cabinet, it is necessary to take the technical data of the drive com-
ponents into account.
Power dissipation
Power dissipation is determined by the current load and the continuous
regenerative power. The actual power dissipation is dependent on the re-
spective cycle load. The servomotor implemented has been laid out for
this load cycle.
On the average, the continuous current at standstill
I
dN
will flow through
the drive controller as a maximum value.

See the respective document "ECODRIVE Servomotors MKD" - Proj-
ect Planning - for the continuous current at standstill

.
⇒
Using the

value of the motor selected, find the value in the diagram
in Fig. 10-1 for the current-dependent power dissipation

.
⇒
Convert the continuous regenerative power found in Tab. Fig. 3-2 with
the factor 0.8. as bleeder-dependent power dissipation
P
V, Bleeder
in the
DKC.
⇒
Add both dissipation values (
P
V,DKC
and
P
V,Bleeder
). Use the total (
P
V,ges
)
for planning the control cabinet.
