PARAMETERS
(2) Disconnected PU detection
This function detects that the PU (FR-PU07) has been disconnected from the drive unit for longer than 1s and causes the
drive unit 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.
(3) 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-PU07).
When the drive unit is stopped by the PU stop function, " " (PS) is displayed. A fault output is not provided.
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-PU07).
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
is valid only in the PU
operation mode.
(4) How to restart the motor stopped by input from the PU in External operation mode (PU stop
(PS) reset method)
The motor can be restarted by making a reset using a power supply reset or RES signal.
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 drive unit.
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.
REMARKS
During operation in the PU operation mode through RS-485 communication from the PU connector, the motor decelerates to stop
(PU stop) when entered from the operation panel .
a) Operation panel
1)After completion of deceleration to a stop, switch OFF the
STF or STR signal.
2)Press to display . ...............( reset)
3)Press to return to .
4)Switch ON the STF or STR signal.
b)Parameter unit (FR-PU07)
1)After completion of deceleration to a stop, switch OFF the
STF or STR signal.
2)Press . .......................................( reset)
3)Switch ON the STF or STR signal.
REMARKS
If Pr.250 Stop selection is set to other than "9999" to select coasting to a stop, the motor will not be coasted to a stop but
decelerated to a stop by the PU stop function during external operation.
