Motor (P7)
For optimal operation, enter the ratings plate information
for the motor here. This information makes up the base
values for the motor controller (electrical reproduction,
see “V/Hz-Characteristic Curve (P11)” on Page 107).
Motor Parameters from Ratings Plate
The motor data is set to the rated operation data for the
frequency inverter and depends on the performance
variables in factory settings.
Switching Type for Motor Stator Windings
When selecting the rating data, take the dependency of the
type of switching on the strength of the feeding input voltage
into account:
●
230V (P7.5) delta circuit A P7.1 = 4A,
●
400V (P7.5) star connection P7.1 = 2.3A.
Circuits (Delta, Star)
Example: Single-phase connection of the MMX12AA4D8_
frequency inverter to a input voltage of 230V. The
stator winding of the motor is connected in a
delta circuit (motor rated current 4A as per
nameplate in figure on this page).
Required changes for the electrical reproduction
for the motor: P7.1 = 4.0, P7.3 = 1410, P7.4 =
0.67.
