Tayfun from Turkeysolar pump inverter is really in very good quality and we also prepared some promotional products for exhibition. We are going to make new orders soon. Last year there was only one local agent and this year, there are more than 8. Some of them only sell Veikong!

Cristian from ChileIt’s very good! LCD options make it much easier to use. That’s the strong point, easy of use. And robust. Great PC software.

Brahim assad from SyriaVFD500 output frequency is stable when the others are fluctuating. Also output current is less than others, that’s why output frequency is higher too which can save more energy.

P40.14  PID output feature 
0: PID output is positive: when the feedback signal exceeds the PID reference value, the output frequency of the inverter will decrease to balance the PID. For example, the strain PID control during wrapup 1: PID output is negative: When the feedback signal is stronger than the PID reference value, the output frequency of the inverter will increase to balance the PID. For example, the strain PID control during wrapdown

P40.17  Proportaional gain KP1 
0.00～10.00 The function is applied to the proportional gain P of PID input. P determines the strength of the whole PID adjuster. The parameter of 100 means that when the offset of PID feedback and given value is 100%, the adjusting range of PID adjust is the Max. frequency (ignoring integral function and differential function).

P40.18  Integral time TI1 
0.01s～10.00s This parameter determines the speed of PID adjustor to carry out integral adjustment on the deviation of PID feedback and reference. When the deviation of PID feedback and reference is 100%, the integral adjustor works continuously after the time (ignoring the proportional effect and differential effect) to achieve the Max. Frequency (P01.06) or the Max. Voltage (P12.21). Shorter the integral time, stronger is the adjustment

1.00s  ☆  
P40.19  Differential time TD1 
0.000s～10.000s This parameter determines the strength of the change ratio when PID adjustor carries out integral adjustment on the deviation of PID feedback and reference. If the PID feedback changes 100% during the time, the adjustment of integral adjustor (ignoring the proportional effect and differential effect) is the Max. Frequency (P01.06) or the Max. Voltage (P12.21). Longer the integral time, stronger is the adjusting.

In some applications, one group PID parameter is not enough, different PID parameters would be adopted according to the situation. The function codes are used to switch two groups PID parameter. The setting mode of the regulator parameters P40.20~P40.22 is similar as P40.17~P40.19’s. Two groups PID parameter can be switched via DI terminal, or switched according to PID deviation automatically. When selection is automatic switching: when the deviation absolute value between given and feedback is smaller than P40.24 (PID parameter switching deviation 1), PID parameter selection is group 1. When the deviation absolute value between given and feedback is bigger than P40.25 (PID parameter switching deviation 2), PID parameter selection is group 2. When the deviation absolute value between given and feedback is between P40.24 and P40.25, PID parameter is the linear interpolation of two groups PID parameter, showed as below parameter switching diagram
