Set the capacity of the second motor.
V/F control
Set the number of poles of the second motor.
V/F control
Set the rated current of the second motor.
The second electronic thermal O/L relay is disabled.
Set the rated voltage (V) of the second motor.
Set the rated frequency (Hz) of the second motor.
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 maximum frequency of an MM-CF motor when MM-CF is
selected.
The Pr.457 setting is used when a motor other than MM-CF is
selected.
Set the motor inertia of the second motor.
9999: The MM-CF inertia is used for the IPM motor MM-CF.
No auto tuning for the second motor.
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).
Tuning data of the second motor
(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.
*5
Set this parameter according to the PM motor specifications.
Value calculated based on the tuning data.
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-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 second 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.
