10.1 Notes on installing the control cabinet
When planning the control cabinet, it is necessary to take the technical
data of the drive components 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 AC motor implemented has been laid out for this
load cycle.
On the average, the maximum continuous current at standstill
I
dN
of the
AC motor will flow through the drive controller.
⇒
See the motor documentation for the continuous current at standstill
I
dN
(see "MKD Digital AC Motors"- Project Planning -).
⇒
Using the
I
dN
value of the motor selected, find the value in the diagram
in Fig. 10-1 for the power dissipation
P
V, DKC
.
⇒
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.
