PARAMETERS
Description of parameters
(1) Reset selection
You can select the enable condition of reset function (RES signal, reset command through communication) input.
When Pr. 75 is set to any of "1, 3, 15, 17", a reset can be input only when the converter is tripped.
(2) Disconnected PU detection
This function detects that the PU (FR-DU07-CNV/FR-PU07) has been disconnected from the converter for 1s or longer
and causes the converter to provide a fault output (E.PUE) and to trip.
When Pr. 75 is set to any of "0, 1, 14, 15", operation continues if the PU is disconnected.
(3) PU stop selection
When Pr. 75 is set to any of "14 to 17", input from the PU stops the converter.
When the converter is stopped by the PU stop function, " " is displayed. A fault output is not provided.
(4) How to restart the motor stopped by input from the PU (PU stop (PS) reset method)
The motor can be restarted by making a reset using a power supply reset or RES signal.
NOTE
Inputting the reset signal (RES) during operation also resets the inverter. The motor coasts since the inverter being
reset shuts off the output. Also, the cumulative value of the electronic thermal relay is cleared.
The reset key of the parameters is only valid when the converter is tripped, independently of the Pr. 75 setting.
NOTE
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 converter.
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.
(a) Operation panel (FR-DU07-CNV)
1)Turn SOF signal ON and stop the converter operation.
2)Press
••••••( reset)
3)Turn SOF signal OFF and restart the converter
operation.
(b) Parameter unit (FR-PU07)
1)Turn SOF signal ON and stop the converter operation.
2)Press
••••••( reset)
3)Turn SOF signal OFF and restart the converter
operation.
CAUTION
Do not reset the converter while the inverter start signal is being input.
Otherwise, the motor will start suddenly after resetting, leading to potentially hazardous conditions.
