Communication parameter settings are not cleared.
At a write, the data is set as the control input command.
At a read, the data is read as the inverter running status.
At a write, the data is set as the operation mode setting.
At a read, the data is read as the operation mode setting.
<Inverter status/control input command>
The signal within parentheses ( ) is the initial status. The description changes depending on the setting of Pr.180 to Pr.189 (input terminal
function selection) (page 430).
For each of the assigned signals, some signals are enabled by NET and some are disabled. (Refer to page 321.)
The inverter run enable signal is in the initial status for the separated converter type.
The signal within parentheses ( ) is the initial status. The description changes depending on the setting of Pr.190 to Pr.196 (output terminal
function selection) (page 384).
No function is assigned in the initial status for the separated converter type.
<Operation mode/inverter setting>
Enable/disable parameter writing by Pr.79 and Pr.340 settings. For the details, refer to page 315.
Restrictions in each operation mode conform with the computer link specification.
