Operation of automatic restart after instantaneous power failure
I have the following questions concerning automatic restart after instantaneous power failure:
1. Is the operation log of automatic restart after instantaneous power failure recorded in the inverter?
I could not find the log after an instantaneous power failure.
2. Is there any method to configure the inverter to output a signal that indicates that automatic restart after instantaneous power failure occurred?
3. When automatic restart after instantaneous power failure occurs, the duct static pressure drop due to coasting greatly affects the production facilities and we are seeking for a countermeasure against this. Is there any method to prevent or reduce this static pressure drop by configuring the inverter?

Answer
1. No operation log is recorded.
2. No. However, you can create a state indicating that automatic restart after instantaneous power failure is in progress by turning the start command (STF and STR) and frequency command (analog, multi-speed) ON and turning the RUN OFF.
3. There is no way to reduce the duct static pressure drop. It is recommended to shorten the restart time (as the motor is coasting).
