Tab. 5-379: System environment variable
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.

Tab. 5-380: Inverter status/control input command
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) (page 5-439).
JOG operation/automatic restart after instantaneous power failure/start self-holding selection/
reset cannot be controlled over a network, so in the initial status bit 6, bit 9, bit 11, and bit 12 are
invalid. To use bit 6, bit 9, bit 11, and bit 12, change the signal by Pr. 185, Pr.186, Pr. 188, or Pr. 189.
The inverter run enable signal is in the initial status for the separated converter type.
