4.4 Integrated power modules: 3-axis CCU box
On the SINUMERIK 810D, three integrated power modules are fitted on one
heat sink in the 3-axis CCU box:
Power module for 2 x 6A/12A (FSD)
Power module for 1 x 18A/36A (FSD) or 24A/32A (MSD)
Heat sink temperature sensor
Table 4-16 Assignment between motor connection and power module
Motor connection
Power module Rated current
(sine, rms)
A1 (rear) 18A/36A (FSD) or 24 A/32A /MSD) 24 A
A2 (center) 6A/12A (only as FSD) 6 A
A3 (front) 6A/12A (only as FSD) 6 A
Note
The spindle can only be used on “A1” on the integrated power module.
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 of > 1000 m, the load currents must be reduced according to the
derating factor.
The diagram is given in Subsection 4.3.3 Installation altitude
