Module racks for CCU integrated power modules: 1 x 18/36A (FSD) or 24/32A (MSD) and 2 x 6/12A (FSD), internal heat dissipation only
Module rack for the CCU integrated power modules: 2 x 9/18/A (FSD), internal/external heat dissipation 

On the SINUMERIK 810D, the number of axes can be expanded to six axes, including spindles.

There are two possibilities :
either Connect axis expansion plug-in unit and SIMODRIVE 611 power module at axis expansion interface,

or Connect SIMODRIVE 611D control plug-in unit with SIMODRIVE 611 power module on drive bus/device bus.

The axis expansion plug-in units are used whenever no more than six measur- ing channels are required for the SINUMERIK 810D. This plug-in unit is plugged into a SIMODRIVE 611 power module. The axis expansion plug-in units are designed for 1-axis and 2-axis power modules. The ribbon cables are part of the plug-in unit.

If the six measuring channels of the SINUMERIK 810D are insufficient, SIMODRIVE 611 controller plug-ins must be inserted into the SIMODRIVE 611 power modules to connect further measuring systems (connection via drive bus with drive bus terminator). If 611D control modules are used, it may be neces- sary to connect the NCU terminal block to the free drive bus connector of the 611D control.

The CCU can control up to 6 axes onboard. For this purpose there is a new expansion plug-in in addition to the existing axis expansion plug-in modules.
All power modules of the 611D series can be connected as external power modules for axis expansion.

As from SW 6.3, the limitation to six drives applies.
Expansion levels 1 to 6 can be achieved by many combinations. To operate the spindle to the internal power module, connect it to the 24A/32A power module (A1).
