Operation command

Tab. 5-284: Operation commands
The signal within parentheses ( ) is the initial status. The description changes depending on the
setting of Pr. 180 to Pr. 184, Pr. 187 (input terminal function selection) (page 5-439).
The inverter run enable signal is in the initial status for the separated converter type.
JOG operation/automatic restart after instantaneous power failure/start self-holding selection/
reset cannot be controlled over a network, so in the initial status bit8 to bit11 are invalid. To use
bit8 to bit11, change the signal by Pr. 185, Pr. 186, Pr. 188, or Pr. 189 (input terminal function
selection) (page 5-439). (A reset can be executed by the instruction code HFD.)
In RS-485 communication from the PU connector, only the forward rotation command and reverse
rotation command can be used.
