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.

The MM-CF constant is used when the IPM motor MM-CF is
selected for the second motor, 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 second motor.
The MM-CF motor maximum frequency is used when the MM-
CF is selected, and Pr.457 setting is used when a motor other
than MM-CF is selected.
Set the inertia of the second motor.
9999: The MM-CF inertia is used for the IPM motor MM-CF.
