Selection of operation mode and
operation location
4
PARAMETERS
(3) Controllability through communication
*1 As set in Pr. 338 Communication operation command source and Pr. 339 Communication speed command source. (Refer to page 204)
*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 186)
*4 Some parameters may be write-disabled according to the Pr. 77
Parameter write selection setting and operating status. (Refer to page 189)
*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 page 62 for the parameter list)Parameter clear is disabled.
*6 When Pr. 550 NET mode operation command source selection = 1 (RS-485 terminals valid) or Pr. 550 NET mode operation command source selection =
9999 and the communication option is not fitted.
*7 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.
