*1 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)
*2 The inverter run enable signal is in the initial status for the separated converter type.
*3 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)
*4 In RS-485 communication from the PU connector, only the forward rotation command and reverse rotation command can be used.
