Note: T1-08 will only be displayed in CLV.
■ T1-09: Motor No-Load Current
Sets the no-load current for the motor.
The default setting displayed is no-load current that was automatically calculated from the output power set in T1-02 and
the motor rated current set to T1-04. Enter the data listed on the motor test report. Leave this data at the default setting if
the motor test report is not available.
■
T1-10: Motor Rated Slip
Sets the rated slip for the motor.
The default setting displayed is the motor rated slip for a Yaskawa motor calculated from the output power set in T1-02.
Enter the data listed on the motor test report.
■
T1-11: Motor Iron Loss
Provides iron loss information for determining the Energy Saving coefficient. T1-11 will first display a value for the
motor iron loss that the drive automatically calculated the when motor capacity was entered to T1-02. If the motor test
report is available, enter the motor iron loss value listed there.
◆ Parameter Settings during PM Motor Auto-Tuning: T2
The T2- parameters are used to set the Auto-Tuning input data for PM motor tuning.
