4. Parameter description
Parameter
<Setting>
• If the value of parameter P.234 is 1, and the signal is on, the triangular wave function is effective.
Please set 36 to any parameter: P.80 ~P.84, P.86, P.126~P.128, corresponding external terminal
assigned for TRI signal.
• If the value of parameter is 2, it means the triangular wave function is effective in anytime.

Output
frequency
Note: 1.The output frequency will be limited by the maximum frequency and minimum frequency when the
triangular wave function is effective.
2. If the amplitude compensation (P.236 or P.237) is too larger, over-voltage trip and stall prevention
operation will automatically run, thus the inverter can not run according to the triangular wave function.
3. This function is valid in V/F curve. It means P.300 must be set to 0.
4.58 Auxiliary frequency function (P.240)
P.240 “Auxiliary frequency function selection”
Parameter Factory setting Setting range Remarks
240 0 0~4 ---
<Setting>
• When the value of P.240 is 0, auxiliary frequency function is not selected.
• When the value of P.240 is 1, operation frequency = basic fre auxiliary frequency (2-5),
• When the value of P.240 is 2, operation frequency = basic fre auxiliary frequency (4-5),
• When the value of P.240 is 3, operation frequency = basic frequency - auxiliary frequency (2-5),
• When the value of P.240 is 4, operation frequency = basic frequency - auxiliary frequency (4-5),
• When the operation frequency is less than P.2, the operation frequency should equal to P.2. When
the operation frequency is more than P.1, the operation frequency should equal to P.1.
Note: Basic frequency is set by the target frequency reference source DU03B, communications or combination of
multi-speed gears.
