*1 For the FR-A820-00077(0.75K) or lower and FR-A840-00038(0.75K) or lower, it is set to 85% of the inverter rated current.
*2 For the FR-A820-03160(55K) or lower, and FR-A840-01800(55K) or lower.
*3 For the FR-A820-03800(75K) or higher, and FR-A840-02160(75K) or higher.
*4 The initial value differs according to the voltage class (200 V / 400 V).
*5 The setting range and unit change according to the Pr.71 (Pr.450) setting.

Set the number of poles of the second motor.
V/F control
This function is enabled when the RT signal is ON.
Set the rated motor current.
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 Pr.84 Rated motor frequency setting is used.
Set the motor inertia of the second motor.
9999: The constant value of Mitsubishi Electric motor (SF-PR,
SF-JR, SF-HR, SF-JRCA, SF-HRCA and so on) is used.
No auto tuning for the second motor.
Offline auto tuning is performed without rotating the second
motor.
Offline auto tuning is performed without rotating the motor (V/F
control, IPM motor MM-CF). (Refer to
Offline auto tuning is performed while rotating the second
motor.

9999: The constant value of Mitsubishi Electric motor (SF-PR,
SF-JR, SF-HR, SF-JRCA, SF-HRCA and so on) is used.
The offline auto tuning automatically sets the gain required for
the frequency search of the second motor.
The constant value of Mitsubishi Electric motor (SF-PR, SF-
JR, SF-HR, SF-JRCA, SF-HRCA and so on) is used for the
second motor.
