n41
Frequency Reference Upper Limit
Setting range 0 to 110 (%) Factory setting 100 (%)
Unit of setting 1 (%)
n42
Frequency Reference Lower Limit
Setting range 0 to 110 (%) Factory setting 0 (%)
Unit of setting 1 (%)
•Set constants in percentage in n41 and n42 based on the constant set in n24 for the
maximum frequency as 100 percent.
•If 0 is set in n41 or n42, the Inverter will continue operating with the constant set in n42.
If the constant set in n42 is smaller than the constant set in n29 for the minimum output
frequency, the Inverter will not operate.

Frequency Reference Input Terminal
Setting range 0, 1 Factory setting 0
This constant can be used to enable the FR terminal to have the fault reset function if the
multi-function input terminals are all occupied with commands, such as multi-step
speed commands 1 and 2.
Value Description
0 Enables the FR terminal to work as a frequency reference terminal.
1 Enables the FR terminal to work as the fault reset input terminal.
