Set the frequency of program running and the running frequency of 7-segment speed
respectively. short-circuit the multi-terminal command 1, 2, 3, 4 with COM combinatorially to
realized the 16-segment speed/acceleration speed.
0Xspeed is the regular running mode,setting source can be adjusted by F02,F03and other
parameters, running time is controlled by the H18.
Terminal multi-segment speed is defined as follows(shorted with COM it is ON, disconnected
then it is OFF)
