5. Determining the maximum energy in the armature circuit for the turn-off operation
Parameter value required:
p51570
MLFB (Order No.) of the SIMOREG CCP
r50072[1] actual rated unit DC current, armature [A]
r50101 rated motor armature voltage [V]

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 p51578 (factory setting = 145)
Required parameter values:
p51570
MLFB (Order No.) of the SIMOREG CCP
r50071 Rated unit supply voltage (armature) [V]
r50072[1] actual rated unit DC current, armature [A]
r50078[0] actual rated converter input voltage, armature [V]
r50101 rated motor armature voltage [V]
p50111 armature circuit inductance [mH]
p50351 Threshold for the undervoltage shutdown [%].
⇒
Determining the setting value according to the parameter description for p51578
The SIMOREG CCP is now ready to run.
