Communication operation and setting
(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 inverter operating status.
*3 For write, set data as the operation mode setting. For read, data is read as the operation mode status.
Real-time monitor
Refer to page 152 for details of the monitor description.
............... Specifications differ according to the date assembled. Refer to page 378 to check the SERIAL number.

<Inverter status/control input instruction>
*1 The signal within parentheses is the initial setting. The description changes depending on the setting of Pr. 180 to Pr. 189 (input
terminal function selection) (page133).
Each assigned signal is valid or invalid depending on NET. (Refer to page 219)
*2 The signal within parentheses is the initial setting. The description changes depending on the setting of Pr. 190 to Pr. 196 (output
terminal function selection) (page140).
