1) Parameter setting
2) How to select a setting value
1: Reset motor parameters (0 after execution)
Motor parameters <F402: Automatic torque boost>, <F912: PM q-axis inductance>, and
<F913: PM d-axis inductance> are set with default setting values.
2: Auto-tuning at run command (0 after execution)
Perform tuning when the motor starts for the first time after settings are made and
automatically set <F402: Automatic torque boost>, <F912: PM q-axis inductance>, and <F913:
PM d-axis inductance> while considering the motor wiring.
3: Auto-tuning at TB ON
Assign "66: Offline auto-tuning" (67 is the inversion signal) to the digital input terminal.
When the assigned input terminal is ON, executed an auto-tuning and automatically set <F402:
Automatic torque boost>, <F912: PM q-axis inductance>, and <F913: PM d-axis inductance>.
This setting allows auto-tuning while the motor is stopped; use this function when the motor
cannot run following the auto-tuning due to some reason related to the operation of the
machinery.
However, if standby signal is OFF, this function will not be enabled.
To make an auto-tuning again, tern input terminal off once, then turn on again.
6: Auto-tuning at run command during TB ON
Assign "66: Offline auto-tuning" (67 is the inversion signal) to the digital input terminal.
When the assigned input terminal is ON, always make an auto-tuning and automatically set
<F402: Automatic torque boost>, <F912: PM q-axis inductance>, and <F913: PM d-axis
inductance> at startup.
7: Auto-tuning F402 only at run command during TB ON
Assign "66: Offline auto-tuning" (67 is the inversion signal) to the digital input terminal.
Always execute an auto-tuning at startup when the motor starts for the first time after the
assigned input terminal is ON and set <F402: Automatic torque boost> only.
3) Cautions during offline auto-tuning
• Offline auto-tuning must be performed with the motor connected but in a completely stopped
state.
Title Parameter name Adjustment range Default setting
F400 Offline auto-tuning 0: -
1: Reset motor parameters (0 after
execution)

4: Motor parameters auto calculation (0 after
execution)
5: -
