Chapter 5 Parameter Introductions
P2.06 Carrier frequency
Inverter Power ( kW)
Carrier frequency
(KHz)
Note:
 In order to achieve better control performance, the maximum frequency should not
be less than 36 times of the carrier frequency of the inverter.

In order to reduce noise, a higher carrier frequency can be set. If absolute silence is
not required during the inverter running, lower carrier frequency can be selected to
reduce the wear and tear of the inverter and intensity of radiation.

If carrier frequency is set larger than factory setting, the rated continuous working
current should be decreased.
P2.07 Jump frequency 1
P2.08 Jump frequency 2
P2.09 Jump frequency 3
P2.10 Jump frequency bandwidth
Note:
 To avoid mechanical resonant, the inverter can skip round some running points,
which is called Jump frequency. As shown in Fig. 5-2-5.
Reference Freq.(Hz)
 The inverter can set three jump frequency points, and the jump frequency
bandwidth can overlap or nesting. If overlapped, the range broadens. When all
three jump frequency set to 0.00 Hz, the jump function will be disabled.
