Motor (P7)
For optimal operation, you should enter the enter the ratings plate
information for the motor here. This information makes up the
base values for the motor controller (electrical reproduction, see
Section “U/f-characteristic curve (P11)”, page 111).
Switching type for stator windings of the motor
When selecting the rating data, take the dependency of the type
of switching on the strength of the feeding mains voltage into
account:
• 230 V (P7.5)
A delta circuit A A P7.1 = 4 A,
• 400 V (P7.5)
A star connection A P7.1 = 2.3 A.
Example
Single-phase connection of the MMX12AA4D8… frequency
inverter to a mains voltage of 230 V. The stator winding of the
motor is connected in a delta circuit (motor rated current 4 A as
per nameplate in figure 84). See
1)
in the factory setting.
Required changes for the electrical reproduction for the motor:
P7.1 = 4.0, P7.3 = 1410, P7.4 = 0.67.
