10.35 CPU time load with SINAMICS DCM
SINAMICS DCM DC Converter
Operating Instructions, 12/2018, A5E34763375A
659
Note
The additional CPU time load listed above for TM15, TM31 and TM150 apply for a sampling
time of 4
ms (p4099 = 4000). Setting faster sampling rates in the TM modules increases the
CPU time load in the SINAMICS DCM to values considerably higher than those st
ated
previously.
Note
The stated computing rules are to be understood as support during configuring and
commissioning. The theoretical CPU time load computed from these rules can deviate from
the CPU time load actually measured on the r9976[1] by sever
al percentage points.
10.35.1
Maximum configuration
The following configuration can be operated as the maximum on one CUD.

Number
Component
Note
3 TM15, TM31, TM150 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
1 SMC10, SMC30 The connection of others (SMC20,..) and of more than
1 external encoder module is not permissible.
1 CBE20 The connection of other OMI modules (CBE10) is not
permissible.

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 628)".
