[Overload Load Level Ratio (Parameter No.143)]
No. Name Unit Input range Default initial value setting
143 Overload load level ratio % 50 to 100 100
Outputs alarm code 048 overload warning (message level) when motor temperature exceeds
the ratio set in this parameter if motor temperature under rated operation is set as 100%.
For details, refer to " Maintenance Section Chapter 1, 1.5 Predictive Maintenance Function /
Overload warning (page C1-15)".
No judgment will be made when set as 100%.
Using this function enables monitoring of motor temperature changes caused by dried-up
grease or wear and tear on parts.
A warning is output when the preset value is exceeded.
This enables detection of abnormalities before a breakdown or a malfunction occurs.
