PARAMETERS
(6) Modbus registers
System environment variable
∗1 The communication parameter values are not cleared.
∗2 For write, set the data as a control input instruction.
For read, data is read as an drive unit operating status.
∗3 For write, set data as the operation mode setting.
For read, data is read as the operation mode status.

<Drive unit status/control input instruction>
∗1 The signal is the initial setting. Definitions change according to the Pr. 180 to Pr. 182 (input terminal function selection) (refer to page 100).
Each assigned signal is valid or invalid depending on NET. (Refer to page 160)
∗2 The signal is the initial setting. Definitions change according to the Pr. 190, Pr. 192 (output terminal function selection) (refer to page106).
