Tab. 5-112: Operation at fault
Selectable with Pr. 75 "Reset selection/disconnected PU detection/PU stop selection"
Selectable with Pr. 122 "PU communication check time interval", Pr. 336 "RS-485 communication
check time interval" , Pr. 548 "USB communication check time interval", and Pr. 1432 "Ethernet
communication check time interval".
Follows the communication option setting.
In the PU JOG operation mode, operation always stops when the PU is disconnected. The operation
of PU disconnection (E.PUE) follows the Pr. 75 "Reset selection/disconnected PU detection/PU stop
selection" setting.
When Pr. 550 "NET mode operation command source selection" = "1" (RS-485 terminals enabled),
or Pr. 550 = "9999" with no communication option connected.
FR-A800-E: When Pr. 550 "NET mode operation command source selection"= "5" (Ethernet connec-
tor enabled), or Pr. 550 = "9999" with no communication option connected.
When Pr. 550 "NET mode operation command source selection" = "0" (communication option
enabled), or Pr. 550 = "9999" with communication option connected.
FR-A800-E only
FR-A800-E: Not available.
