(2) Overload advance notice
When the load is high, it is possible to adjust the load again by outputting an overload advance notice.
It is used to prevent damage to the machine from too much load, i.e. baggage on a conveyor, the Inverter
overload protection will operate.
Assign 03(OL) to an intelligent output terminal 11, 12 or the alarm relay output terminal.
