■ T1-04: Motor Rated Current
Sets the motor rated current according to the motor nameplate value. Set the motor rated current between 50% and 100%
of the drive rated current for optimal performance in OLV or CLV. Enter the current at the motor base speed.
■
T1-05: Motor Base Frequency
Sets the motor rated frequency according to the motor nameplate value. If a motor with an extended speed range is used
or if the motor is used in the field weakening area, enter the maximum frequency to E1-04 (E3-04 for motor 2) after
Auto-Tuning is complete.
■
T1-06: Number of Motor Poles
Sets the number of motor poles according to the motor nameplate value.
■
T1-07: Motor Base Speed
Sets the motor rated speed according to the motor nameplate value. If a motor with an extended speed range is used or if
the motor is used in the field weakening area, enter the speed at base frequency to T1-07.
■
T1-08: PG Number of Pulses Per Revolution
Sets the number of pulses from the PG encoder. Set the actual number of pulses for one full motor rotation.
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 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.
