*1 Input this value when A1-02 = 3 [Control Method = CLVector].
*2 0 Hz is displayed as the initial value. If you do not know the Motor Rated Slip Frequency, keep the setting at 0 Hz.
*3 Input this value when A1-02 = 0 or 1 [Control Method = V/f Control or PG V/f Control].
*4 If T1-12 = 1 [Test Mode Selection = Yes], when you run the motor in Drive Mode for the first time after Auto-Tuning, the drive will
automatically set E2-02 [Mot Rated Slip] and E2-03 [Mot No-Load Current].
*5 Input this value when T1-01 [Auto-tuning Mode Selection] = 0 Hz.
*6 Set the same value to No-Load Voltage as T1-03 [Motor Rated Voltage] to get the same characteristics using Yaskawa 1000-Series
drives or other legacy models.
◆ Auto-Tuning for PM Motors
This section gives information about Auto-Tuning for PM motors. Set these parameters for Auto-Tuning:
• Motor parameters E1-xx [E1: V/F PARAMETER MOTOR 1], E5-xx [E5: PM MOTOR SETTINGS]
• Speed feedback detection uses F1-xx [F1: ENCODER] (only with PM CLVector)

PM Motor Parameter Settings T2-01 = 0
• When the information from the motor test report or
motor nameplate is not available.
• Rotational/Stationary Auto-Tuning that energizes
the motor is not done. Manually input the necessary
motor parameters.

PM Static Full AutoTune T2-01 = 1
• When the information from the motor test report or
motor nameplate is not available.
Note:
With Stationary Auto-Tuning, the energized drive
stays stopped for approximately 1 minute. During
this time, the drive automatically measures the
necessary motor parameters.

PM Static R Autotune T2-01 = 2
• After Auto-Tuning, the wiring distance between the
drive and motor changed by 50 m or more.
• When the motor output and drive capacity are
different.
