Omron 3G3M1-A4007-ECT User Manual

Overload Warning
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.
•
To output this signal, allocate “38: OL (Overload warning)” or “37: OL2 (Overload warning 2)” to Out-
put Terminal [DO1] Function Selection (E20), Output Terminal [DO2] Function Selection (E21) and
Output Terminal [ROA, ROB] Function Selection (E27). (Two types of overload warning signals can
be output.)
• When using “38: OL (Overload warning),” set the overload warning detection level and overload
warning detection timer for each of 1st and 2nd control. When using “37: OL2 (Overload warning 2),”
set Overload early warning 2 Level (OL2) (E34) and Overload early warning 2 Detection Timer
(OL2) (E35) regardless of 1st and 2nd control.
