•
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 linkagefunction please refer to
P.185
.
3. Seclection 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
.

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.
