Auto-Tuning of PG-E3 Encoder
Characteristics
<1>
<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).
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
selection and the tuning process.

Table 4.7 Types of Auto-Tuning for Permanent Magnet Motors
Setting
• Use if a motor test report is available.
T2-01 = 0 • 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.
• Use if a motor test report is not available.
T2-01 = 1 • Input motor data from the motor name plate. Make sure to convert data into the correct units. The drive automatically calculates the
motor data.
• Tunes stator resistance only.
T2-01 = 2
• Should be performed if the motor cabling has changed.
• Use if a motor test is not available.
• Tunes the Motor Induction Voltage only.
T2-01 = 11
• 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).
T2-01 = 12 Perform this Auto-Tuning to obtain accurate position data from the motor rotor for driving a PM motor.
