Mitsubishi Electric FR-F820-00046 Instruction Manual page 498

*1 The signal within parentheses ( ) is the initial status. The description changes depending on the setting of Pr.180 to Pr.189 (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 bit 8 to bit 11 are invalid. To use bit 8 to bit 11, change the signal by Pr.185, Pr.186, Pr.188, or Pr.189 (Input terminal function
selection) (page 355) (A reset can be executed by the instruction code HFD.)
*4 During RS-485 communication through the PU connector, only the Forward rotation command and Reverse rotation command signals can be
used.
