PARAMETERS
(3) Controllability through communication
Controllability through communication in each operation mode is shown below.
Monitoring and parameter read can be performed from any operation regardless of operation mode.
 As set in Pr.338 Communication operation command source and Pr.339 Communication speed command source. (Refer to page 195)
 At occurrence of RS-485 communication error, the drive unit 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 178)
 Some parameters may be write-disabled according to the Pr.77 Parameter write selection setting and operating status. (Refer to page 181)
 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.
 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 fitted.
 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.
 Available with multi-speed setting and terminal 4-5 (valid when AU signal is ON).
