As set in Pr. 338 Communication operation command source and Pr. 339 Communication speed command source (Refer to page 214)

At occurrence of RS-485 communication error, the inverter cannot be reset from the computer.

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 193)

Some parameters may be write-disabled according to the Pr. 77 Parameter write selection setting and operating status. (Refer to page 196)

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 64) Parameter clear is disabled.

Available with multi-speed setting and terminal 4-5 (valid when AU signal is ON).

Can be selected using Pr. 122 PU communication check time interval.

In the PU JOG operation mode, operation is always stopped when the PU is disconnected. Whether fault (E.PUE) occurrence is allowed or not is as set in
Pr. 75 Reset selection/disconnected PU detection/PU stop selection.
