Selection of operation mode and operation location
4
PARAMETERS
*1 As set in Pr. 338 Communication operation command source and Pr. 339 Communication speed command source. (Refer to page 322)
*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 Reset selection/disconnected PU
detection/PU stop selection. (Refer to page 305)
*4 Some parameters may be write-disabled according to the Pr. 77 Parameter write selection setting and operating status. (Refer to page 307)
*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 71 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.
(4) Operation at alarm 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, Pr. 336 RS-485 communication check time interval or Pr. 548 USB communication
check time interval.
*3 As controlled by the communication option.
*4 In the PU jog operation mode, operation is always stopped when the PU is disconnected. Whether fault (E.PEU) occurrence is allowed or not is as
set in Pr. 75 Reset selection/disconnected PU detection/PU stop selection.
*5 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
*6 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
