Parameters
Description
Tuning data
(The value measured by offline auto
tuning is automatically set.)
9999: Uses the MM-CF constant for
the IPM motor MM-CF, and the
inverter internal data for a PM motor
other than MM-CF.
Set this parameter according to the
PM motor specifications.
The value calculated by the motor
constant parameter setting is used.
Set the exponent n when the
induced voltage constant phi f
n
(Pr. 706) is multiplied by 10 .
No exponent setting
Tuning data
(The value measured by offline auto
tuning is automatically set.)
9999: Uses the MM-CF constant for
the IPM motor MM-CF, and the
inverter internal data for a PM motor
other than MM-CF.
Set the maximum current (OCT) level
of the motor.
Uses the MM-CF constant for the IPM
motor MM-CF, and 200% for a PM
motor other than MM-CF.
Set this parameter when using the
second motor.
(the same specifications as Pr. 71).
The function is disabled.
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.
Second electronic thermal O/L relay
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.
