4.5 Integrated power modules: 2-axis CCU box
On the SINUMERIK 810D, 2 integrated power modules are fitted on one heat
sink in the 2-axis CCU box:
Power module for 9A/18A (FSD)
Heat sink temperature sensor
The 2-axis CCU box can be mounted with internal or external heat dissipation.
Table 4-17 Assignment between motor connection and power module
Motor connection
Power module Rated current
(sine, rms)
A1 (rear) 9A/18A (only as FSD) 9 A
A2 (front) 9A/18A (only as FSD) 9 A
Note
The 3rd drive number “A3” can be used for an axis in “Axis expansion plug-in
unit left”.
All the technical details apply for ambient temperatures up to max. 40 C. At
ambient temperatures > 40, linear current derating is necessary, as in the case
of the OI power supply. At maximum ambient temperature 55 C: Current
derating to 60 % of the 40 C value.
All power ratings apply up to an installation altitude of 1000 m. At an installation
altitude > 1000 m, the load currents must be derated according to the diagram
for the OI power supply.
The diagram is given in Subsection 4.3.3 Installation altitude
