(common)
You can select the reset input acceptance, disconnected
PU (FR-DU07/FR-PU04/FR-PU07) connector detection
function and PU stop function.

(1) Reset selection
You can select the enable condition of reset function
(RES signal,
communication) input.
When [Pr. 75 = 0, 2, 14, 16] and the reset signal
(RES) is input during operation, the motor coasts
since the inverter being reset shuts off the output. In
addition, the cumulative values of the electronic
thermal relay and regenerative brake duty are
cleared.
When [Pr. 75 = 1, 3, 15, 17], a reset can be input only
when a fault occurs.
The reset key of the PU is only valid when the
inverter is tripped, independently of the [Pr. 75]
setting.
Name Initial Value
If the PU is disconnected, operation will
be continued.
When the PU is disconnected, the
inverter output is shut off.
If the PU is disconnected, operation will
be continued.
When the PU is disconnected, the
inverter output is shut off.

Disconnected PU Detection
(2) Disconnected PU detection
Removal or reinstallation of the PU (FR-DU07/FR-
PU04/FR-PU07) will not pose a problem. However, if
the PU is accidentally removed in the PU operation
mode, only resetting the power can stop the motor.
When [Pr. 75 = 2, 3, 16, 17] and this function detects
that the PU (FR-DU07/FR-PU04/FR-PU07) has been
disconnected from the inverter for 1s or longer, the
inverter provides a fault output (E.PUE) and comes to
trip. When the PU has been disconnected since
before power-ON, it is not judged as a fault.
When [Pr. 75 = 0, 1, 14, 15] , operation is continued if
the PU is disconnected. Note that the motor
decelerates to stop when the PU is disconnected
during PU/JOG operation.
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.

PARAMETER
Description
For the initial value, reset always enabled,
without disconnected PU detection, and
with PU stop function are set.
PU Stop Selection
Pressing decelerates the motor
to a stop only in the PU operation mode.
Pressing decelerates the motor to
a stop in any of the PU, External and
communication operation modes.
