V5 series inverter
54
P0.12 Carrier frequency Range: 1.0K~14.0K 8.0K
The default carrier frequency below 3.7kW inverter is 5.0 kHz; it is 3.0 kHz for 5.5kW and larger inverters.
Carrier frequency will effects the motor’s noise and heat loss.The relationship among carier frequency, motor noise, leak
current, and interference are shown below:
Note：(1) In order to achieve better performances, the ratio of carrier
Note: (1) to obtain the best control features, the ratio of carrier frequency and highest running frequency must more than
36.
(2) When the carrier frequency is low, the current display value may be error.
P0.13 Acc/Dec mode Range: 0, 1 0
0: Linear Accerlate/Decelerate mode
Output frequency increases or decreases as a constant slope, see Fig. 4-4.
1: S curve Accerlate/Decelerate mode
Output frequency increases or decreases as S-curve, see Fig.4-5.
Fig.4-4 Linear Acc/Dec
Fig.4-5 S-curve
P0.14 Low speed time of S curve Range: 10.0%~50.0% (Acc/Dec time), P0.14＋P0.15<90% 20.0%
P0.15 Linear time of S curve Range: 10.0%~80.0％ (Acc/Dec time), P0.14＋P0.15<90％ 60.0%
P0.14 and P0.15 are only valid when Acc/Dcc mode is S curve Acc/Eec mode (P0.13 ＝1) and P0.14+P0.15 < 90%.
Low speed time of S curve is shown in Fig.4-5 ③, the output frequency slope increases from 0.
Linear time of S curve is shown in Fig.4-5 ②, the output frequency slope is constant.
High speed time of S curve is shown in Fig.4-5 ①, the output frequency slope decreases to 0.
High speed time＝100%－P0.14－P0.15.
Note: S curve Acc/Dec mode is suitable for the start/stop of elevator, conveying belt, conveying load and so on .
