*1 For the FR-F820-02330(55K) or lower and FR-F840-01160(55K) or lower.
*2 For the FR-F820-03160(75K) or higher and FR-F840-01800(75K) or higher.
*3 The initial value differs according to the voltage class (200 V / 400 V).
*4 The setting range and unit change according to the Pr.71 (Pr.450) setting.
• The settings are valid under PM motor control.
• The offline auto tuning enables the operation with SPM motors and IPM motors other than the MM-EFS or MM-THE4. (When
a PM motor other than the IPM motor MM-EFS or MM-THE4 is used, always perform offline auto tuning.)
• Tuning is enabled even when a load is connected to the motor.
• Reading/writing of the motor constants tuned by offline auto tuning are enabled. The offline auto tuning data (motor constants)
can be copied to another inverter using the operation panel.
• The offline auto tuning status can be monitored on the operation panel or the parameter unit.

Set the inertia of the second motor.
9999: The MM-EFS/MM-THE4 inertia is used for the IPM motor
MM-EFS/MM-THE4.
No auto tuning for the second motor.
Offline auto tuning is performed without the motor rotating
(motor other than IPM motor MM-EFS or MM-THE4).
Offline auto tuning is performed without the motor rotating (V/F
control, IPM motor MM-EFS/MM-THE4).

motor MM-EFS/MM-THE4 is selected, and the inverter internal
data is used when a PM motor other than the MM-EFS or MM-

Set this parameter according to the PM motor specifications.
The value calculated from the parameter setting for motor
constant is used.
Set the exponent n when the induced voltage constant phi f
(Pr.738) is multiplied by 10
No exponent setting
Tuning data of the second motor
(The value measured by offline auto tuning is automatically
set.)
9999: The MM-EFS/MM-THE4 constant is used when the IPM
motor MM-EFS/MM-THE4 is selected, and the inverter internal
data is used when a PM motor other than the MM-EFS or MM-
THE4 is selected.
Set the maximum current (OCT) level of the second motor.
The MM-EFS/MM-THE4 constant is used when the IPM motor
MM-EFS or MM-THE4 is selected, and 200% is used when a
PM motor other than the MM-EFS or MM-THE4 is selected.
