Manual Setting of the Motor Parameters
Motor Rated Current Setting (E2-01)
Set E2-01 to the rated current value on the motor nameplate.
Motor Rated Slip Setting (E2-02)
Set E2-02 to the motor rated slip calculated from the number of rated rotations on the motor nameplate.
Motor No-Load Current Setting (E2-03)
Set E2-03 to the motor no-load current at the rated voltage and rated frequency. Normally, the motor no-load
current is not written on the motor nameplate. Consult the motor manufacturer.
Factory setting is the no-load current value for a standard Yaskawa 4-pole motor.
Number of Motor Poles Setting (E2-04)
E2-04 is displayed only when Closed Loop Vector control method is selected. Set the number of motor poles
as written on the motor nameplate.
