◆If standby function is enabled and the ac drive is just in the standby operating mode,
regardless of the value of P2.04, the ac drive will run at zero-speed.
P2.05 Frequency departure setting
Range: 0.00～2.50Hz【0.00Hz】
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.
P2.06 Carrier frequency
Range: 1～16.0kHz
Ac drive Power ( kW) ≤11
15～45 55～75
93 ≥110
Carrier frequency
(KHz)
1.0～16.0
【8.0】
1.0～10.0
【6.0】
1.0～6.0
【3.0】
1.0～4.5
【2.5】
1.0～4.5
【2.0】
Note:
◆In order to achieve better control performances, the maximum frequency should not
less than 36 times of the carrier frequency of the ac drive.
◆In order to reduce noise, a higher carrier frequency can be set. If absolute silence is not
required during the ac drive running, lower carrier frequency can be selected to reduce
the wear and tear of the ac drive 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: 0.00～Max frequency 【0.00Hz】
P2.09 Jump frequency 3
Range: 0.00～Max frequency 【0.00Hz】
P2.10 Jump frequency bandwidth
Range: 0～15.00Hz【0.00Hz】
Note:
◆To avoid mechanical resonant, the ac drive can skips round some running points,
which is called Jump frequency. As shown in Fig. 5-2-5.
