Example case where overload limit function is activated during deceleration
(during regeneration)
For the 3G3MX2-EV2 Series, the overload limit function does not work during deceleration stop.
Therefore, even if the output current value exceeds the overload limit level due to regeneration, the
inverter continues the deceleration stop.
