During automatic tuning, the motor may rotate, so always confirm safety before starting automatic
tuning.
Separate the motor from the load and machine, etc., and run the motor as a stand alone unit during
automatic tuning.
Even when Mode 1 is executed, the motor may rotate due to vibration, etc.
If the vibration is large, turn the
key immediately to stop operation.
Always check the safety on the load side before executing automatic tuning, regardless of the Mode 1
or 2 setting.
With Mode 2, the motor will automatically start rotating.
If the automatic tuning function does not end correctly, always turn the inverter power OFF before
investigating or confirming the operation.
Automatic tuning can be carried out only in the Local Mode.
If the motor has an unstable frequency band, automatic tuning may not end normally. In this case, the
maximum torque boost function cannot be used.
Always ground the motor and inverter.
If the load is less than 30% and the fluctuation does not occur, automatic tuning can be carried out with
the load and machine connected. However, the performance may not be complete.
Always carry out automatic tuning before using the maximum torque boost function.
The contact output FLT will function if the automatic tuning does not end correctly. In equipment that
uses this contact, keep the operation of the related devices in mind.
