P2.05 Frequency departure setting
Range: 0.002.50Hz0.00Hz
Note:
This function is used to prevent the fluctuations of analog input and reduce the
influence to output frequency .The backlash is 20% of frequency departure setting.

Note:
In order to achieve better control performances, the maximum frequency should not
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
Range: 0.00~Max frequency 0.00Hz
P2.08 Jump frequency 2
Range: 0.00Max frequency 0.00Hz
P2.09 Jump frequency 3
Range: 0.00Max frequency 0.00Hz
P2.10 Jump frequency bandwidth
Range: 015.00Hz0.00Hz
Note:
To avoid mechanical resonant, the inverter can skips round some running points,
which is called Jump frequency. As shown in Fig. 5-2-5.
