Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
The overload warning function causes the inverter to output an overload warning if the load is too large,
before it detects an overload trip.
This is useful to prevent mechanical damage to transfer machines etc. due to overweighed loading, or
stoppage of transfer lines due to an overload, through the use of the overload protection function of the
inverter.
Allocate the Multi-function Output 11/12 selection (C021/C022) or the Multi-function Relay Output (AL1,
AL2) Function Selection (C026) to 03 (OL: Overload warning) or 26 (OL2: Overload warning 2). (Two
types of overload warning signals can be output.)
