Notes:
1.
The inverter automatically restarts the operation after the retry waiting time Set for
Pr.68. Therefore,
if
the retry function is used, pay suffcient care
so
that restarting
of the inverter wiii not constitute hazards to the operators.
2.
In
the inverter reset operation by the retry function, the accumulated data of
electronic thermal relay and regeneration brake duty ratio, etc. is not cleared.
This reset is different from the power reset operation.
