• 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 value of P.240 is 5, 2-5 terminals given as a proportion linkage signal,
• When the value of P.240 is 6, 4-5 terminals given as a proportion linkage signal.
• When the operation frequency is less than P.2, the operation frequency should be equal to P.2. When
the operation frequency is more than P.1, the operation frequency should equal to P.1.
Note: 1. Basic frequency is set by the target frequency reference source operation panel, communications, analog
signal (2-5/4-5) input or combination of multi-speed gears.
2. The proportion linkage function please refer to P.185.
3. Seclecting the 4-5 external analog signal (voltage or current) input terminals, please refer to P.17; the
frequency range of the external analog signal, please refer to P.38 and P.39.

<Setting>
• If P.242=0, the DC injection brake function before starting is not selected. If P.242=1, the DC brake
injection function before starting is selected. When the output frequency reached the starting
frequency (P.13), a DC voltage (P.244) will be injected into the motor windings by the inverter,
which is used to lock the motor rotor. The DC brake operation will last for a period (the set value of
P.243) before the motor start.
As shown as follows:
