■ 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
Table 4.8 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 110 for details on the tuning mode
selection and the tuning process.

Type
<1> Available in drive software versions PRG: 7017 or later.
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).
Setting Requirements and Benefits
Motor Data Input 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).
