YASKAWA ELECTRIC TOEP C710616 38F YASKAWA AC Drive L1000A Quick Start Guide
T1-03: Motor Rated Voltage
Sets the motor rated voltage according to the motor nameplate value. Enter the motor voltage at base speed here if the
motor is operating 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.
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.
No.
<1> Values shown are specific to 200 V class drives. Double value for 400 V class drives. Multiply value by 2.875 for 600 V class drives.
