∗1
As set in Pr.338 Communication operation command source and Pr. 339 Communication speed command source (Refer to page 197)
∗2
At occurrence of RS-485 communication error, the inverter cannot be reset from the computer.
∗3
Enabled only when stopped by the PU. At a PU stop, PS is displayed on the operation panel. As set in Pr. 75 PU stop selection. (Refer to page 179)
∗4
Some parameters may be write-disabled according to the Pr. 77 Parameter write selection setting and operating status. (Refer to page 182)
∗5
Some parameters are write-enabled independently of the operation mode and command source presence/absence. When Pr. 77 = 2, write is enabled.
(Refer to the parameter list on page 58) Parameter clear is disabled.
∗6
When Pr. 550 NET mode operation command source selection = "2" (PU connector valid) or Pr. 550 NET mode operation command source selection = "9999" and the
communication option is not fitted.
∗7
When Pr. 550 NET mode operation command source selection= "0" (communication option valid) or Pr. 550 NET mode operation command source selection= "9999"
and the communication option is fitted.
