
Settings in the communication parameters are not cleared.

The data is written as a control input command for writing.
The data is read as the inverter status for reading.

The data is written as an operation mode setting for writing.
The data is read as the operation mode status for reading.

The Pr.811 setting is available only for the FR-A800-E inverter.

The signal within parentheses ( ) is the initial status. The input signal function can be changed using Pr.180 to Pr.189 (Input terminal function
selection). JOG operation/automatic restart after instantaneous power failure/start self-holding selection/reset cannot be controlled over a
network, so in the initial status bit6, bit9, bit11, and bit12 are invalid. To use bit6, bit9, bit11, and bit12, change the signal by Pr.185, Pr.186,
Pr.188, or Pr.189.
For details of Pr.180 to Pr.189, refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.

The inverter run enable signal is in the initial status for the separated converter type.

The signal within parentheses ( ) is the initial status. The output signal function can be changed using Pr.190 to Pr.196 (Output terminal
function selection).
For details of Pr.190 to Pr.196, refer to the Instruction Manual (Detailed) of the FR-A800/FR-F800 inverter.

No function is assigned in the initial status for the separated converter type.
