Disconnected PU detection
This function detects that the PU (FR-PU04/FR-PU07) has been disconnected from the inverter for longer than 1s and
causes the inverter to provide a fault output (E.PUE) and come to trip.
When Pr. 75 is set to any of "0, 1, 14, 15", operation is continued if the PU is disconnected.
REMARKS
When the PU has been disconnected since before power-ON, it is not judged as a fault.
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"
(which selects 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 STOP
key of the operation panel or parameter unit (FR-PU04/FR-PU07, operation panel for FR-E500 (PA02)).
When the inverter is stopped by the PU stop function, "
After the motor is stopped from the PU, it is necessary to perform PU stop (PS) reset to restart. PS reset can be made from
the unit from which PU stop is made (operation panel, parameter unit (FR-PU04/PU07, operation panel for FR-E500
(PA02)).
The motor can be restarted by making PS cancel using a power supply reset or RES signal.
When Pr. 75 is set to any of "0 to 3", PU stop (PS display) is invalid, deceleration to a stop by
operation mode.
REMARKS
During operation in the PU operation mode through USB communication or RS-485 communication from the PU connector, the
motor decelerates to stop (PU stop) when entered from the operation panel
