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 second.
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 on the
PU 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.
Do not reset the inverter with the start signal on.
Otherwise, the motor will start instantly after resetting, leading to
potentially hazardous conditions.
