Sinamics Dcm Commissioning Steps - Siemens SIMOREG DC-MASTER Operating Instructions Manual

Commissioning
7.2.2

SINAMICS DCM commissioning steps

Note
If the basic converter unit has a software release from V 1.2 and higher, the SIMOREG CCP can be
commissioned by selecting p50051=30 (automatic setting of the parameters for SIMOREG CCP).
This optimization run must be performed after commissioning step 4. In this case, commissioning
steps 3, 5 and 6 are not performed. If Fault F60050 occurs during the optimization run (optimization
run interrupted internally) the fault description of the particular fault value (r50047) provides
information about possible causes.
1. Connect SIMOREG CCP according to the recommended connection in Chapter 6.
2. Set p50790=6 (communication with the CCP).
Correct communication is optically displayed using an LED on the Power Interface module
C98043-A7046:
LED flashes slowly (<1 Hz)
LED flashes quickly (approx. 3 Hz)
3. Determining the setting value for parameter p51577 (factory setting = 1600)
Required parameter values:
r50070...MLFB (characteristic number) of the SINAMICS DCM
r51570...MLFB (characteristic number) of the SIMOREG CCP
⇒ Determining the setting value according to the parameter description for p51577
4. Commission the basic converter unit according to the operating instructions SINAMICS
DCM, Chapter 7.
The commissioning must be correctly completed. This also means that the optimization runs
according to commissioning step 8 must be performed.
The optimization run for the pre-control and current controller for the armature and field
(p50051=25) is absolutely mandatory, as the armature inductance is determined in this run
and the value of p50111 is required for the subsequent SIMOREG CCP commissioning.
Notice:
p50351 must not be parameterized more negative than the factory setting. Otherwise, when
the line contactor is closed (or the circuit breaker) then a charging current surge occurs in
the chopper capacitors. This can destroy the CCP power semiconductors.
Comment:
The chopper capacitors are charged via an internal pre-charging circuit. When reaching the
undervoltage threshold defined by p50351, the line contactor (or circuit breaker) is closed,
which means that the pre-charging circuit is bypassed.
Note:
If Fault F60300 occurs when commissioning the basic unit (especially during the
optimization runs), then the commutation monitoring must be deactivated for the
commissioning (p51580=0). After commissioning has been successfully completed, the
commutation monitoring must be reactivated (p51580=7).
Notice:
If an existing drive system was retrofitted with a SIMOREG CCP, then the optimization run
for the pre-control and current controller for the armature (p50051=25) and field
(p50051=24) is absolutely necessary. The value of p50111 determined in this optimization
run is required to commission the SIMOREG CCP. Parameter p50111 can be modified
through manual optimization. This is the reason that before performing the optimization run,
the actual value of p50111 should be noted and only set again after the SIMOREG CCP
commissioning has been completed.
