Example: Motor parameters (P7)
For optimal operation, you should enter the ratings plate information for the motor here.
This information makes up the base values for the motor controller (electrical reproduction).
Figure 14: Motor Parameters From Ratings Plate
When selecting the rating data, take the dependency of the type of switching on the strength
of the feeding mains voltage into account:
● 230V (P7.5)  delta circuit A  P7.1 = 4A
● 400V (P7.5)  star connection  P7.1 = 2.3A
Figure 15: Circuits (Delta, Star)
Example: Single-phase connection of the MMX12AA4D8… adjustable frequency drive to a
230V mains voltage. The stator winding of the motor is connected in a delta circuit
(motor rated current 4A as per rating plate Figure 14). See
1)
in the factory settings.
Required changes for the electrical reproduction for the motor:
P7.1 = 4.0, P7.3 = 1410, P7.4 = 0.67
P7.5 = 230V und P7.6 = 50 Hz are the default settings (P1.3 = 0) of the MMX12.
The motor data is set to the rated operation data for the adjustable frequency drive and
depends on the performance variables in factory settings (see 1)).
