Parameter Description
5.55 Auxiliary Frequency Function (P.240)
P.240 “Auxiliary frequency function selection”
Parameter Factory Setting Setting Range Remarks
--- 6~0 0 042
<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 frequency + auxiliary frequency (2-5),
• When the value of P.240 is 2, operation frequency = basic frequency + 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.
5.56 DC Injection Brake Function before Starting (P.242~P.244) V/F
P.242 “DC injection brake function before starting selection”
P.243 “DC injection brake time before starting”
P.244 “DC injection brake voltage before starting”
Parameter Factory Setting Setting Range Remarks
--- 1~0 0 242
--- s06~0 s5.0 342
--- %03~0 %4 442
<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.
