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
r071
r072i002
P078i001
P101
P111
P351
⇒ Determining the setting value according to the parameter description for U578
The SIMOREG CCP is now ready to run.
