â—† T1: Induction Motor Auto-Tuning
T1 parameters set the Auto-Tuning input data for induction motor tuning.
Note:
• The base frequency of drive-dedicated motors and special vector-control motors can be lower than the base frequency of general-purpose
motors, which is 50 Hz or 60 Hz. In these conditions, the drive uses the lower frequency as the value for E1-06 [Base Frequency] and E1-
04 [Maximum Output Frequency] after Auto-Tuning completes. If the maximum output frequency is too low and causes problems, change
the setting of E1-04 after Auto-Tuning completes.
• The drive automatically sets these induction motor parameters:
–E1-xx [V/f Pattern for Motor 1]
–E2-xx [Motor Parameters]

Motor Rated Power Uses the units set in o1-58 [Motor Power Unit Selection] to set the motor rated output power. Determined by o2-04

â– T1-03: Motor Rated Voltage
No.
(Hex.)
Name Description

Motor Rated Voltage Sets the rated voltage (V) of the motor. Enter the base speed voltage for constant output motors. Determined by o2-04
(208/240 V: 0.0 - 255.5 V,
480 V: 0.0 - 511.0 V)
If you do Auto-Tuning on a drive-dedicated motor or a special vector-control motor, the voltage or frequency can be
lower than a general-purpose motor. Always compare the data from the nameplate or test report with the Auto-Tuning
results and check for differences. Enter the voltage necessary to operate the motor in no-load conditions at rated speed
for better control precision around rated speed. If the motor test report or the motor nameplate is not available, enter
approximately 90% of the motor rated voltage.
If the drive input power supply voltage is low, enter approximately 90% of the input voltage. When the input power
supply voltage is low, the current will increase. Make sure that the main power supply capacity is correct and use a
molded-case circuit breaker for the drive.
