n
T1-03: Motor Rated Voltage
Sets the motor rated voltage according to the motor nameplate value. Enter the voltage at base speed if the motor will
operate above base speed.
Enter the voltage needed to operate the motor under no-load conditions at rated speed to T1-03 for better control
precision around rated speed when using a vector control mode. The no-load voltage can usually be found in the motor
test report available from the manufacturer. If the motor test report is not available, enter approximately 90% of the rated
voltage printed on the motor nameplate. This may increase the output current and reduce the overload margin.
No.
T1-03
<1> Values shown are specific to 200 V class drives. Double value for 400 V class drives.
n
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. Enter the current at the motor base speed.
No.
T1-04
n
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.
No.
T1-05
n
T1-06: Number of Motor Poles
Sets the number of motor poles according to the motor nameplate value.
No.
T1-06
n
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.
