Note
The capacity of the SINAMICS DCM can be expanded by equipping the SINAMICS DCM
with a 2nd CUD (right-hand mounting slot). See Chapter "Expanding the SINAMICS DCM to
include a second CUD (Page 590)".

Computation examples

Example 1:
Project A is a single drive in a control cabinet. An AOP30 is located in the control cabinet
door. The motor has a pulse encoder, which is connected through the pulse encoder input

10.33 CPU time load with SINAMICS DCM
Note
Connection of any combination of TM15, TM31 and
TM150 modules on DRIVE-CLiQ. The connection of
other TM modules (TM17, TM41,..) and of more than
3 TM modules is not permissible.
Sampling in 4 ms cycle (p4099=4000). Faster
sampling increases the CPU time load, and precludes
operation of this maximum configuration
The connection of others (SMC20,..) and of more than
1 external encoder module is not permissible.
The connection of other OMI modules (CBE10) is not
permissible.
