The inverter automatically sets appropriate parameters for operation.
If you do not set the acceleration and deceleration times and V/F pattern, you can run the inverter as if

appropriate values had been set in the corresponding parameters. This operation mode is useful to start
operation immediately without making fine parameter settings.
