*4
Test Mode Selection
No-load voltage
*1 Input this value when A1-02 = 3 [Control Method Selection = Closed Loop Vector].
*2 Shows 0 Hz as the default 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 w/ PG].
*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 Motor Parameters for PM Motor

This section gives information about Auto-Tuning for PM motors. Auto-Tuning sets these parameters:
• Motor parameters E1-xx, E5-xx
• Speed feedback detection uses F1-xx (only with CLV/PM)

Table 4.8 Auto-Tuning for PM Motors
Parameter Settings Application Conditions and Benefits
• When the information from the motor test report or
motor nameplate is available.
T2-01 = 0
• Rotational/Stationary Auto-Tuning that energizes the
motor is not done. Manually input the necessary
motor parameters.
• When the information from the motor test report or
motor nameplate is not available.
Note:
T2-01 = 1
With Stationary Auto-Tuning, the energized drive
stays stopped for approximately 1 minute. During
this time, the drive automatically measures the
necessary motor parameters.
• After Auto-Tuning, the wiring distance between the
drive and motor changed by 50 m or more.
T2-01 = 2
• When the motor output and drive capacity are
different.
• When you do not know the encoder Z-pulse offset.
• When the encoder was replaced
• If you have compensated for the deviation from Z
T2-01 = 3 phase (Δθ).
Note:
The motor will rotate slowly while the drive
measures the encoder base position.
