Set the rated motor current.
Set the rated motor voltage (V).
Set the rated motor frequency (Hz).
The MM-CF constant is used when the IPM motor MM-CF is
selected, and the inverter internal data is used when a PM
motor other than MM-CF is selected. Use the correct setting
according to the motor specification.
Set the permissible speed (frequency) of the motor.
The MM-CF motor maximum frequency is used when the IPM
motor MM-CF is selected, and Pr.84 setting is used when a PM
motor other than MM-CF is selected.
Set the motor inertia.
9999: The MM-CF inertia is used for the IPM motor MM-CF.
No offline auto tuning
Offline auto tuning is performed without rotating the motor
(motor other than IPM motor MM-CF).
Offline auto tuning is performed without rotating the motor (for
IPM motor MM-CF).

9999: The MM-CF constant is used when the IPM motor MM-
*2*5
CF is selected, and the inverter internal data is used when a PM
motor other than MM-CF is selected.
*5
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.706) is multiplied by 10
No exponent setting
Tuning data
(The value measured by offline auto tuning is automatically
set.)
9999: The MM-CF constant is used when the IPM motor MM-
CF is selected, and the inverter internal data is used when a PM
motor other than MM-CF is selected.
Set the maximum current (OCT) level of the motor.
The MM-CF constant is used when the IPM motor MM-CF is
selected, and 200% when a PM motor other than MM-CF is
selected.
Adjust the target current during tuning.
100%
Set this parameter when using the second motor
(the same specifications as Pr.71).
The function is disabled.
