Mitsubishi Electric FR-F800 Series Instruction Manual page 520

*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)
*4 During RS-485 communication through the PU connector, only the Forward rotation command and Reverse rotation command signals can be
used.
