As set in Pr.338 Communication operation command source and Pr. 339 Communication speed command source (Refer to page 171)
∗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 153)
∗4
Some parameters may be write-disabled according to the Pr. 77 Parameter write selection setting and operating status. (Refer to page 156)
∗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 52) Parameter clear is disabled.
∗6
Available with multi-speed setting and terminal 4-5 (valid when AU signal is ON).
