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).
