Additional Information
• To check the status of the electronic thermal function, use the Electronic Thermal Load Rate
Monitor (d104). An Overload trip (E05) error will occur if the value reaches 100%.
• This inverter has the free-electronic thermal function. The free-electronic thermal function
allows you to set the reduction factor for overload detection based on your application.
For details, refer to
7-8-1 Free-electronic Thermal Function on page 7-72.
• The electronic thermal function can output a warning signal before the inverter is stopped by
an overload detection.
The use of a warning signal is effective to reduce the system down time because it enables
you to solve problems previously.
For details, refer to
7-8-3 Electronic Thermal Warning on page 7-75.
