This programming example is designed to write the parameter data in the 3G3FV Inverter. After writing
has been completed, be sure to send an enter command to enable the written data as the Inverter op-
eration data.
To use special remote I/O, it will be necessary to switch the remote I/O operation. Refer to 5-3 Switching
