How to make a restart after a stop by the key on the PU
(1) Operation panel
1) After completion of deceleration to a stop, switch off the STF or STR signal.
2) Press the key two times* to display .
(For the monitor screen) ......Refer to page 68 for the monitor display provided by
pressing the key.
3) Press the key.
4) Switch on the STF or STR signal.
(2) Parameter unit (FR-PU04)
1) After completion of deceleration to a stop, switch off the STF or STR signal.
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: When Pr. 79 = 3, press the key three times, to display .
Then, press the key and proceed to step 3).
Note:1. If the reset signal (RES) is provided during operation, the inverter shuts off its
output while it is reset, the data of the electronic thermal relay function 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 1s. 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. 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.
5. When the inverter 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.
CAUTION
Do not reset the inverter with the start signal on.
Otherwise, the motor will start instantly after resetting, leading to
potentially hazardous conditions.
