When debugging, first enter this parameter, the setting range of this parameter is ±12.5%, and the setting accuracy is 0.1%, but this parameter itself is not displayed, but the measured value of generator voltage is displayed, so as long as this parameter is adjusted so that the displayed value is the same as the actual value That's it, very convenient. Note that if the difference between the displayed value and the actual value exceeds ±8%, it is better to modify the measured voltage divider resistance first, and then adjust this parameter.

However, when the 1# channel is set to the working mode of line co-frequency and grid connection, this parameter should be set to "power angle", the setting range is 10°～60°, and the setting accuracy is 1°. Parameters 18, 19, and 20 are generally used for generator parameter settings, and parameters 42, 43, and 44 are generally used for similar circuit parameter settings. However, the settings of parameters 18, 19 and 20 are always consistent with the working mode selection of 1# channel, when all 8 channels are connected to the grid at the same frequency When 1# channel takes parameters18, 19, 20, other channels take parameters 42, 43, 44.

When parameter 9 is set to digital voltage regulation and parameter 10 is set to pulse width voltage regulation, its meaning is digital single-shot voltage regulation pulse width. Equivalent to the digital potentiometer ±1 digit when the button is pressed the maximum time our company's digital potentiometer is designed to be 0.3S
