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.
As the inverter internal data is used for the second motor, set it
correctly according to the motor specifications.
Set the permissible speed (frequency) of the second motor.
The Pr.457 setting is used.
Set the motor inertia of the second motor.
9999: Inverter internal data
No auto tuning for the second motor.
Offline auto tuning is performed without the motor rotating.
Offline auto tuning is performed only for motor constant R1
(without motor rotation)
Encoder position tuning and offline auto tuning are performed
(with the motor rotating slightly).
