    Veikong solar 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!

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

    VEIKONG VFD500 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.

  DC bus voltage control

Overvoltage stall control: limit the power generation of the motor by adjusting the output frequency to avoid skipping the voltage fault;
Undervoltage stall control: control the power consumption of the motor by adjusting the output frequency to avoid yaw failure
VdcMax Control: Limit the amount of power generated by the motor by adjusting the output frequency to avoid over-voltage trip;
VdcMin control: Control the power consumption of the motor by adjusting the output frequency, to avoid jump undervoltage fault

  Carrier frequency 1kHz~12kHz(Varies depending on the type)
  Startup method

Direct start (can be superimposed DC brake); speed tracking start

Sleeping function

41 Group Sleeping function
P41.00 Sleep mode and wake up selection

Unit’s digit: sleep mode selection
0:no sleep function
1:sleep by frequency
2:AI1 sleep (AI1 as pressure feedback)
3:AI2 sleep(AI2 as pressure feedback)
4:AI3 sleep (AI3 as pressure feedback)
3:AI4 sleep(AI4 as pressure feedback)
Ten’s digit :wake up mode selection
0:wake up by frequency
1:AI1 wake up (AI1 as pressure feedback)
2:AI2 wake up (AI2 as pressure feedback)
3:AI3 wake up (AI3 as pressure feedback)
4:AI4 wake up (AI4 as pressure feedback)
Hundred’s digit:Sleep wake direction selection
0: positive direction
Sleep source (AI1 ~ AI4) > P41.03, inverter will sleep
Wake-up source (AI1 ~ AI4) < P41.04, the inverter will wake up
1: reverse direction
Sleep source (AI1 ~ AI4) < P41.03, inverter sleep
Wake-up source (AI1 ~ AI4) > P41.04, the inverter wakes up.

  • When the sleep source and wakeup source are the same, please pay attention to the size relationship of P41.03 and P41.04. If the parameter setting is unreasonable, when the wake-up condition is selected, even if the sleep condition is established, the sleep state cannot be entered, and special attention is required when using.
P41.01 Sleep setting value by frequency 0.00Hz~600HZ,It will sleep if value is less than this value 0.00Hz
P41.02 Wake up threshold by frequency 0.00hz~600.00hz, ,It will wake up if value is bigger than this value


When selecting frequency sleep and frequency wake-up, it must be set by P41.01 < P41.02. When the frequency
source is PID setting, and the frequency wake-up must be set to PID shutdown operation: P40.39 = 1.

P41.03 Sleep setting value by pressure 0~100.0% 0.0%
P41.04 Wake up threshold by pressure 0.~100.0% 0.0%
P41.05 Sleep delay time 0.0s~6000.0s 0.0s
P41.06 Wake up delay up 0.0s~6000.0s 0.0s
P41.07 Sleep decelerating time

Setting value decide by P03.16
P03.16 = 2, 0.00~600.00s;
P03.16 = 1, 0.0s~6000.0s;
P03.16 = 0, 0s~60000s
P41.07 set to 0,sleeping stop mode to free coast.
