Communication operation and setting
(6) MODBUS registers
The following shows the MODBUS registers for system environment variables (read/write), real time monitor items (read),
parameters (read/write), fault history data (read/write), and model information monitor items (read).
 System environment variable

The communication parameter values are not cleared.

For write, set the data as a control input instruction.
For read, data is read as an drive unit operating status.

For write, set data as the operation mode setting.
For read, data is read as the operation mode status.
