5.17.1 Reset selection/PU stop selection (Pr. 75)
(1) PU stop selection
Setting Pr. 75 = "14 to 17" enables the emergency stop with the on the operation panel in the PU and Network operation
modes.
When the inverter 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 operation panel.
Cancel the PS indication and restart the operation by resetting the power or by performing an error reset of FL remote
communication.
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.
(2) How to restart the motor stopped by input from the PU in Network operation mode (PU stop
(PS) reset method)

Pressing decelerates the motor to a
stop only in the PU operation mode.

Pressing decelerates the motor to a
stop in the PU and Network operation modes.
The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 167)
This parameter allows its setting to be changed during operation in any operation mode even if "0 (initial value) or 1" is set in Pr. 77 Parameter write
selection. Also, if (all) parameter clear is executed, this setting will not return to the initial value.
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.
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 FL remote communication operation.
CAUTION
Do not reset the inverter while the start signal is being input. Otherwise, the motor will start instantly after
resetting, leading to potentially hazardous conditions.
