4.4 Integrated power sections: 3-axis CCU box
With the SINUMERIK 810D, three integrated power sections are mounted in the
3-axis CCU box on a heatsink:
S Power section for 2x 6A/12A (FDD)
S Power section for 1x 18A/36A (FDD) or 24A/32A (MSD)
S Heatsink temperature sensor.

current (sine, rms)
A1 (back) 18A/36A (FDD) or 24A/32A /MSD) 24O
A2 (center) 6A/12A (as FDD only) 6O
A3 (front) 6A/12A (as FDD only) 6O
Note
On the integrated power section, the spindle must only be used at “A1”.
All technical data are valid for ambient temperatures up to max. 40 _C. In the
event of ambient temperatures > 40_C currents must be reduced linearly as for
the OI mains supply. At a maximum ambient temperature of 55_C: current
reduction to 60% of the 40_C value.
All the specified load currents are valid up to a site altitude of 1000m. For site
altitudes > 1000m, load currents must be reduced in accordance with the OI
mains supply chart.
For use as an FSD power section (A1 --A3)
