GROUP
D
: Valid : Invalid : Partially valid
 Follows the Pr.338 Communication operation command source and Pr.339 Communication speed command source settings. (Refer to
page 316.)
 At occurrence of RS-485 communication error, the inverter cannot be reset from the computer.
 PU stop is only enabled. PS is displayed on the operation panel during PU stop. Follows the Pr.75 Reset selection/disconnected PU
detection/PU stop selection setting. (Refer to page 259.)
 Writing of some parameters may be disabled by the Pr.77 Parameter write selection setting and the operating condition. (Refer to page 267.)
 Some parameters are write-enabled independently of the operation mode and command source presence/absence. Writing is also enabled
when Pr.77="2". (Refer to page 267.) Parameter clear is disabled.
 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.
 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.
