Parameter Settings During Induction Motor Auto-Tuning: T1 - YASKAWA T1000A Technical Manual

4.6 Auto-Tuning
u Parameter Settings during Induction Motor Auto-Tuning: T1
The T1- parameters are used to set the Auto-Tuning input data for induction motor tuning.
Note: For motors that are to be operated in the field weakening range, first perform the Auto-Tuning with the base data. After Auto-
Tuning is complete, change the maximum frequency E1-04 to the desired value.

Note: The maximum applicable motor capacity varies based on whether the drive is set for Normal Duty or Heavy Duty performance
(C6-01). Refer to Table A.2
n
T1-03: Motor Rated Voltage
Sets the motor rated voltage according to the motor nameplate value. If the motor to be operated above its base speed,
enter the voltage at base speed here.
For better control precision around rated speed when using a vector control mode, it can be helpful to enter the no-load
voltage for the motor here. The motor's "no-load voltage" refers to the voltage needed to operate the motor under no-load
conditions at rated speed. The no-load voltage can usually be found in the motor test report available from the
manufacturer. If no data is available, enter approximately 90% of the rated voltage printed on the motor nameplate. Note
that this might increase the output current reducing the overload margin.
