Description
VMIVME-7455 the action of the lifting tool tilting 1 # screw on page 4205 of program drawing PC2 as an example, it can be seen from the logic block PC2.4.2.42 in Figure 1 that there are two situations when the 1 # screw needs to be extended. The first situation is to manually adjust at the front end of the boom, and at this time, as long as the manual adjustment command is given, that is, ST_ SCRWJ1_ MAN_ CW_ O is 1, and it is not necessary to meet the allowable conditions for the tilting operation of the lifting tool to make the 1 # screw extend and have action. The second scenario is that the instruction of the cab crane tilt adjustment handle, the tilt 1 # encoder extension stop signal, and the VMIVME-7455 conditions for crane tilt operation are met. As long as SCRW1_ END_ L_ EXT (tilt 1 # encoder extension stop signal) is 0, while ST_ TLS_ ON_ When the ALLOWED (allowable condition for lifting tool tilting operation) is 1, and the cab lifting tool tilting adjustment command is received, then the 1 # screw extends and acts. The contraction action is the same.
