SIMOREG DC-MASTER commissioning steps

Note
The parameter values to be set when commissioning the SIMOREG CCP must be graphically
determined using the characteristic diagram (Appendix).
Alternatively, an existing commissioning script for the DriveMonitor can be used (script fileccp.ssc
and database filesimoreg-ccp-mlfb.xml).
If the basic converter unit has a software release from V 3.1 and higher, SIMOREG CCP can be
commissioned by selecting P051=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 F050 occurs during the optimization run (optimization run cannot
be performed) the fault description of the particular fault value (r047.001) provides information about
possible causes.
1. Connect SIMOREG CCP according to the recommended connection in Chapter 6.
2. Set P790=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 U577 (factory setting = 1600)
Required parameter values:
r070...MLFB (characteristic number) of the SIMOREG DC-MASTER
n570...MLFB (characteristic number) of the SIMOREG CCP
⇒ Determining the setting value according to the parameter description for U577
4. Commission the basic converter unit according to the operating instructions SIMOREG DC-
MASTER, 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
(P051=25) is absolutely mandatory, as the armature inductance is determined in this run and
the value of P111 is required for the subsequent SIMOREG CCP commissioning.
Notice:
P351 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 P351, the line contactor (or circuit breaker) is closed,
which means that the pre-charging circuit is bypassed.
Note:
If Fault F030 occurs when commissioning the basic converter unit (especially during the
optimization runs), then the commutation monitoring should be deactivated for the
commissioning (U580=0). After commissioning has been successfully completed, the
commutation monitoring must be reactivated (U580=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 and field (P051=25) is absolutely
necessary. The value of P111 determined in this optimization run is required to commission
the SIMOREG CCP. Parameter P111 can be modified through manual optimization. This is
the reason that before performing the optimization run with P051=25, the actual value of
