Overload Warning
If the applied load is large, the Inverter can output an overload warning signal before an
overload trip occurs.
This helps prevent mechanical damage due to an overload in the carrier machine, or an
operation line stop due to overload protection of the Inverter.
Allocate "03: OL (Overload warning)" or "26: OL2 (Overload warning 2)" to any Multi-function
Output Terminal Selections (C021 to C022) or Multi-function Relay Output Function Selection
(C026). (Two types of overload warning signals can be output.)
