■ Input Data for Induction Motor Auto-Tuning
To do Auto-Tuning, input data for the items in Table 3.7 that have an "x". Before starting Auto-Tuning, record the
information on the motor nameplate as a reference.

*1 Input this value when A1-02 = 3 [Control Method Selection = Closed Loop Vector].
*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 Selection = V/f Control or V/f Control with Encoder].
*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 [Motor Rated Slip] and E2-03 [Motor No-Load Current].
*5 Input this value when T1-10 [Motor Rated Slip Frequency] = 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, E5-xx
• Speed feedback detection uses F1-xx (only with CLV/PM)
