*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.
× × ×
Encoder Offset Autotune T2-01 = 3
• When you do not know the encoder Z-pulse offset.
• When the encoder was replaced
• If you have compensated for the deviation from Z
phase (Δθ).
Note:
The motor will rotate slowly while the drive
measures the encoder base position.
- - ×
PM Rotary Autotune T2-01 = 4
• When the information from the motor test report or
motor nameplate is available.
• When you can decouple the motor and load the
motor can rotate freely while Auto-Tuning.
Values measured during Auto-Tuning are
automatically set to the motor parameters.

■ Input Data for PM Motor Auto-Tuning
To do Auto-Tuning, input data for the items in the following tables that have an "×". Before starting Auto-Tuning,
prepare the motor test report or record the information on the motor nameplate as a reference.
