SIMOREG DC-MASTER Converter Commutation Protector Operating Instructions
P111 should be noted and only set again after the SIMOREG CCP commissioning has been
completed.
5. Determining the maximum energy in the armature circuit for the turn-off operation
Parameter value required:
n570 MLFB (Order No.) of the SIMOREG CCP
r072i002 Actual rated unit DC current, armature [A]
P101 Rated motor armature voltage [V]
1.)
P111 Armature circuit inductance [mH]
as well as a characteristic diagram according to the following table:

1.) Rated DC voltage according to the motor rating plate (the values are typical rated data
for Siemens DC motors from the product catalog DA12
2.) The characteristic diagrams are provided in the appendix to these operating instructions
If the graphically determined value lies below the limit line W_max, then the energy reduction
in the armature circuit is assured using the SIMOREG CCP.
6. Determining the setting value for parameter U578 (factory setting = 145)
Required parameter values:
n570 MLFB (Order No.) of the SIMOREG CCP
r071 Rated unit supply voltage (armature) [V]
r072i002 Actual rated unit DC current, armature [A]
P078i001 Actual rated converter input voltage, armature [V]
P101 Rated motor armature voltage [V]
P111 Armature circuit inductance [mH]
P351 Threshold for the undervoltage shutdown [%].
⇒ Determining the setting value according to the parameter description for U578
The SIMOREG CCP is now ready to run.
