12.11 T: AUTOTUNING
Numbers identifying the T parameters are displayed when an LED keypad is used. The names of the parameters
are displayed on the LCD screen of the LCD keypad. Set the following.
• Induction Motor Auto-Tuning
• PM Motor Auto-Tuning
• ASR and Inertia Tuning
◆ T0: TUNE MODE
■ T0-00 Tune Mode Selection
When your control method supports Control Tuning, set T0-00 first. Then, set T1-00 [Mot1/Mot2 Selection] to
select the motor you will tune. Then, set the tuning mode in T2-01 [PM AutoTune Mode Select] or T3-00 [Control

0 : Motor Parameter Tuning
1 : Control Tuning
Note:
The available tuning modes are different for different control methods.
◆ T1: INDUCTION MOTOR
T1 parameters set the Auto-Tuning input data for induction motor tuning.
Note:
• The base frequency of drive dedicated motors and special motors for use with vector control may be lower than the base frequency of
general-purpose motors, which is 50 Hz or 60 Hz. In such cases, this lower frequency is used as the value for E1-06 [Base Frequency]
and E1-04 [Max Output Frequency] after Auto-Tuning completes. If the maximum output frequency is too low and causes problems,
change the setting of E1-04 after Auto-Tuning completes.
• The following induction motor parameters are set automatically.
–E1: V/F PARAMETER MOTOR 1
–E2: MOTOR 1 PARAMETERS
–E3: V/F PARAMETER MOTOR 2
–E4: MOTOR 2 PARAMETERS
–F1: ENCODER (only with Closed Loop Vector Control)

Mot1/Mot2 Selection
Sets which motor to tune when motor 1/2 switching is enabled. You can only use the keypad to set
this parameter. You cannot use external input terminals to set it.

Note:
Set H1-xx = 16 [Motor 2 Selection] ON to set this parameter. The keypad will not show this parameter when H1-xx = 16 is OFF.
1 : Motor 1 (sets E1-xx, E2-xx)
Auto-Tuning automatically sets parameters E1-xx and E2-xx for motor 1.
2 : Motor 2 (sets E3-xx, E4-xx)
Auto-Tuning automatically sets parameters E3-xx and E4-xx for motor 2. Make sure that you connect motor 2 to
the drive for Auto-Tuning.
