SINUMERIK 810D Manual Hardware Configuration (PHC) -- 11.02 Edition
4.5 Integrated power sections: 2-axis CCU box
With the SINUMERIK 810D, two integrated power sections are mounted in the
2-axis CCU box on a heatsink:
S Power section for 9A/18A (FDD)
S Heatsink temperature sensor.
The 2-axis CCU box can be fitted either with internal cooling or with external
cooling.
Table 4-18 Motor connection and power section assignments
Motor
connection
Power section Continuous current, rated
current (sine, rms)
A1 (back) 9A/18A (as FSD only) 9O
A2 (front) 9A/18A (as FSD only) 9O
Note
The third drive number, “A3”, cannot be used for an axis with CCU1/CCU2, it
must not be assigned. Measuring encoder input X413 can be parameterized for
a direct measuring system.
CCU3: The third drive number, “A3”, can be used for an axis in the “left axis
expansion plug--in unit”.
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 applicable 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 --A2).
