PARAMETERS
(2) Controllability through communication
Controllability through communcation in each operation mode is shown below.
Monitoring and parameter read can be performed from any operation regardless of operation mode.
∗1 As set in Pr.338 Communication operation command source and Pr. 339 Communication speed command source (Refer to page 176)
∗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 158)
∗4 Some parameters may be write-disabled according to the Pr. 77 Parameter write selection setting and operating status. (Refer to page 161)
∗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 56) Parameter clear is disabled.
∗6 Available with multi-speed setting and terminal 4-5 (valid when AU signal is ON).
(3) Operation at error occurrence
∗1 Can be selected using Pr. 75 Reset selection/disconnected PU detection/PU stop selection.
∗2 Can be selected using Pr. 122 PU communication check time interval.
∗3 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.
