Parameter
Disconnected PU detection
This function detects that the PU (FR-DU07/FR-PU04/FR-PU07) has been disconnected from
the inverter for longer than 1s and causes the inverter to provide an alarm output (E.PUE) and
come to an alarm stop.
When Pr. 75 is set to any of "0, 1, 14, 15, 100, 101, 114, 115", operation is continued if the PU
is disconnected.
NOTES When the PU has been disconnected since before power-on, it is not judged as an alarm.
To make a restart, confirm that the PU is connected and then reset the inverter.
The motor decelerates to a stop when the PU is disconnected during PU jog operation with
Pr. 75 set to any of "0, 1, 14, 15" (operation is continued if the PU is disconnected).
When RS-485 communication operation is performed through the PU connector, the reset
selection/PU stop selection function is valid but the disconnected PU detection function is
invalid.
PU stop selection
In any of the PU operation, external operation and network operation modes, the motor can be
stopped by pressing the STOP key of the PU
When the inverter is stopped by the PU stop function (refer to section 4.3 "Operation panel FR-
DU07") in the external operation mode, "PS" is displayed but an alarm is not output. An alarm
output is not provided.
When Pr. 75 is set to any of "0 to 3, 100 to 103", deceleration to a stop by the STOP key is valid
only in the PU operation mode.
NOTE The motor will also decelerate to a stop (PU stop) when is input during operation in the PU
mode through RS-485 communication with Pr. 551 "PU mode operation command source
selection" set to "1" (PU mode RS-485 terminal).
