Reset selection
You can select the enable condition of reset function (RES signal, reset command through com-
munication) input.
When Pr. 75 is set to any of "1, 3, 15, 17", a reset can be input only when the inverter is tripped.
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 an alarm output (E.PUE) and come to an
alarm stop.
When Pr. 75 is set to any of "0, 1, 14, 15", operation is continued if the PU is disconnected.
NOTES
When the reset signal (RES) is input during operation, the motor coasts since the inverter
being reset shuts off the output. Also, the cumulative value of the electronic thermal relay
function and the regenerative brake duty are cleared.
The reset key of the PU is valid only when the protective function is activated, independently
of the Pr. 75 setting.
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 RS485 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.
