9-3-3 Writing Parameter Data
This programming example is designed to write the parameter data in the 3G3MV Inverter. After writ-
ing has been completed, be sure to send an enter command to enable the written data as the
Inverter operation data.
To use special remote I/O, it will be necessary to switch the remote I/O operation. Refer to
