CHARACTERISTICS

6.1

Overload protection characteristics

An electronic thermal is built into the converter unit to protect the converter unit from overloads.
[7E Overload 1] occurs when overload operation exceeds the electronic thermal protection curve shown in this section. [7F 
Overload 2] occurs when operation continues above the rated speed and rated torque. Use the equipment within the area on 
the left side of the graph.

Graph of overload protection characteristics

The table lists the converter units and corresponding graphs of overload protection characteristics.

■

Characteristic A

*1 A resistive force of 100 % indicates the continuous rating of the converter unit.
