Auto-Tuning for Permanent Magnet Motors
Automatically sets the V/f pattern and motor parameters E1-, E5-, and some F1- parameters for speed
feedback detection.
Table 4.7 Types of Auto-Tuning for Permanent Magnet Motors
lists the data that must be entered for Auto-Tuning. Make sure the data is available before starting Auto-Tuning.
The information needed is usually listed on the motor nameplate or in the motor test report provided by the motor
manufacturer. Also refer to
Flowchart C: Auto-Tuning for PM Motors on page 107
for details on the tuning mode
selection and the tuning process.

Requirements and Benefits
Motor Data Input
<1> Auto-Tuning of PG-E3 encoder characteristics requires a PG-E3 option with software version 1102 or later. To identify the PG-E3 software
version, refer to the PG-E3 labeling on the option in the field designated “C/N” (S + four-digit number).
T2-01 = 0
• Use if a motor test report is available
• Input motor data from the motor test report. Convert data into the correct unit before inputting data if necessary.
• Motor does not rotate during Auto-Tuning
Stationary Auto-Tuning
T2-01 = 1
• Use if a motor test report is not available
• Input motor data from the motor name plate. Make sure to convert data into the correct units. The drive automatically calculates the
motor data.
Stationary Stator Resistance Auto-
Tuning
T2-01 = 2
• Tunes stator resistance only.
• Should be performed if the motor cabling has changed.
Rotational Back EMF Constant
Auto-Tuning
T2-01 = 11
• Use if a motor test is not available
• Tunes the Motor Induction Voltage only
• Should be performed after Motor data are set and the encoder offset is adjusted.
• The motor must be uncoupled from the mechanical system (remove ropes).
Auto-Tuning of PG-E3 Encoder
Characteristics
T2-01 = 12
Use in CLV/PM control mode to obtain accurate position data from the motor rotor for driving a PM motor.
Input Value
<1> Depends on T2-13 setting.
