Replacement of the CUD: When replacing the left or right-hand (optional) CUD, the
parameters must be loaded to the replacement module e.g. using the STARTER or memory
card. Alternatively, system-specific parameters can be entered via the BOP20 or AOP30 at
the left-hand CUD or with the AOP30 at the right-hand CUD.
Once the parameters have been loaded, "copy from RAM to ROM" must be performed.
When using the DCC, the memory card of the old module must be inserted in order to load
the DCC plan and the program library into the CUD.
Note:
If a memory card is inserted in the CUD during the copy RAM to ROM procedure, the
parameter is not only saved in the ROM of the module but also on the memory card. This
memory card can now be inserted into the replacement module. In the case of a subsequent
"Power ON", the parameters are then loaded from the memory card into the RAM of the
module.
Note:
If the parameter assignment is loaded to a drive with a different MLFB 6RA80..., the
software is able to detect that the parameter assignment does not match the drive. In this
case, the device remains in power up with "33" displayed at the BOP20, as the device and
motor-related parameters are no longer applicable. The user must confirm that this data
should be accepted. Set p9905=2 to continue powering up.
Note:
Before replacing the modules, all the inputs and outputs of the SINAMICS DCM,
including those of the electronics voltage supply, must be de-energized.
Replacing a device:
Same procedure as replacing the CUD.
Note:
Prior to returning the faulty CUD or device, remove the memory card and use this in
the replacement product for loading the parameters.
Distribution of functions to the modules in the SINAMICS DCM:
The purpose of this list is to show which modules are involved in the various actual value
acquisitions, to help ascertain which modules need to be replaced if a fault occurs. You will
find the part number of the module in the screen print on the module. It is C98043-A.....
You will find the order number for spare part orders in spare part list on Spares on Web.

: See block diagram in Section 6.3 of the Operating Instructions.
Processor electronics for open-loop and closed-loop control; part number:
C98043-A7100-L1/L3 (Standard CUD), C98043-A7100-L2/L4 (Advanced CUD).
Evaluation of the analog and binary inputs and outputs
Evaluation of motor temperature sensor KTY84 / PTC / PT100 / NTC
Serial interfaces, parallel connection interface,
Pulse encoder evaluation: For possible pulse encoders, see the parameter description for
P00400.
Note
: Evaluation of the tracks of the pulse encoder is performed by means of differential
amplifier for evaluating the push-pull tracks of pulse encoders. A-A/, B-B/. If only signals A,
B, and not cross-signals A/ and B/ exist, the negative signal inputs of the differential
amplifiers, terminals: X177.44, 46, 48 are to be connected to the electronics ground.
