How to make a restart after a stop made by the
external operation
(1) Operation panel (FR-DU04)
1) After completion of deceleration to a stop, switch off the STF or STR signal.
2) Press the key two times* to call the

4) Turn on the STF or STR signal.
(2) Parameter unit (FR-PU04)

2) Press the key.

3) Switch on the STF or STR signal.
The other way of making a restart other than the above method is to perform a power-reset or to make a
reset with the inverter reset terminal.
Note: 1. By entering the reset signal (RES) during operation, the inverter shuts off output while it is reset, the data
of the electronic overcurrent protection and regenerative brake duty are reset, and the motor coasts.
2. The PU disconnection detection function judges that the PU is disconnected when it is removed
from the inverter for more than 1 s. If the PU had been disconnected before power-on, it is not
judged as an alarm.
3. To resume operation, reset the inverter after confirming that the PU is connected securely.
4. When PU disconnection detection is set and the PU is then disconnected during PU jog operation, the
motor decelerates to a stop. The motor will not stop if a PU disconnection alarm occurs.
5. The Pr. 75 value can be set any time. Also, if parameter (all) clear is executed, this setting will not
return to the initial value.
6. When the motor is stopped by the PU stop function, PS is displayed but an alarm is not output.
When the PU connector is used for RS-485 communication operation, the reset selection and PU
stop selection functions are valid but the PU disconnection detection function is invalid.
7. The reset key of the PU is only valid when the protective function is activated, independent of the
Pr. 75 setting.
Do not reset the inverter with the start signal on.
Otherwise, the motor will start instantly after resetting, which may lead to hazardous
conditions.
