*1 RS-485 communication via PU connector
*2 Follows the Pr.338 Communication operation command source and Pr.339 Communication speed command source settings. (Refer to
page
*3 At occurrence of RS-485 communication error, the inverter cannot be reset from the computer.
*4 Only PU stop is enabled. "PS" is displayed on the operation panel during PU stop. The operation follows the Pr.75 Reset selection/
disconnected PU detection/PU stop selection setting. (Refer to
*5 Writing of some parameters may be disabled by the Pr.77 Parameter write selection setting and the operating condition. (Refer to
*6 Some parameters are write-enabled independently of the operation mode and command source presence/absence. Writing is also enabled when

*7 When Pr.550 NET mode operation command source selection = "1" (RS-485 terminals enabled), or Pr.550 NET mode operation command
source selection = "9999" with no communication option connected.
*8 When Pr.550 NET mode operation command source selection = "0" (communication option enabled), or Pr.550 NET mode operation
command source selection = "9999" with communication option connected.

*2 Selectable with Pr.122 PU communication check time interval, Pr.336 RS-485 communication check time interval, and Pr.548 USB
communication check time interval.
*3 The operation depends on the communication option setting.
*4 In the PU JOG operation mode, operation always stops when the PU is disconnected. The operation at a PU disconnection fault (E.PUE)
occurrence is as set in Pr.75 Reset selection/disconnected PU detection/PU stop selection.
*5 When Pr.550 NET mode operation command source selection = "1" (RS-485 terminals enabled), or Pr.550 NET mode operation command
source selection = "9999" with no communication option connected.
*6 When Pr.550 NET mode operation command source selection = "0" (communication option enabled), or Pr.550 NET mode operation
command source selection = "9999" with communication option connected.
