Rexroth MLD-S Tech-FB Library MLD-S Technology Library 1-31 Fig. 1-43: IndraLogic, cyclic task time • Setup cycle time of the PLC task in [us] where function block MX_MasterSimulator is running in • Setup cut drum axis • Setup the mechanical settings of the cut drum axis (travel ranges, limits) • In order to switch the format between the CAM and the CAM shaft distance on the fly you have to set (see Fig 4-23): • Reduction (P-0-0755) to “1” • P-0-0094 (CAM shaft switch angle) usually to 180 deg • P-0-0144 (CAM shaft distance switch angle) the same as P-0-0094 • P-0-0088, Bit 4 = 1 (change gear switching at the same time as the cam shaft distance switching • P-0-0755 = 1 (Reduction) DOK-MLD-S*-TechFB*****-AW01-EN-D
1-32 MLD-S Technology Library Rexroth MLD-S Tech-FB Library Reduction / P-0-0755: One cut cylinder could carry more than 1 knife, currently only “1” Gear switch on distance switch / P-0-0088, Bit4=1 This value defines, that new gear settings become active with a new hub factor or a cam table switching. CAM shaft switch angle This option defines, when a CAM is activated. A new CAM becomes valid as soon as the cam passes the "cam switch angle" (P-0-0094). In crosscutter applications the "cam shaft distance switch angle" must be 180,0000deg. CAM shaft distance switch angle This option defines, when a new value for the hub factor ("cam shaft distance") is activated. A new hub factor becomes valid as soon as the cam passes the "cam shaft distance switch angle" (P-0-0144). In crosscutter applications the "cam shaft distance switch angle" must be 180,0000deg. Fig. 1-44: parameter setting with DriveTop • Set the synchronisation acceleration (P-0-0142) and the synchronisation velocity (P-0-0143) of the cut drum axis • →DriveTop → Right mouse button → Single parameter → P-0-0142 (and P-0-0142) • Depending on the master drive polarity (P-0-0108) set the synchronization direction (P-0-0154), the synchronization mode (P-0- 0155) and the command value mode (S-0-0393) of the cut drum axis • →DriveTop → Right mouse button → Single parameter → P-0-0154 (and P-0-0155, and S-0-0393) • In order to count your cuts you have to define a certain range inside of the cutangle. The “CutCounter” FB-output will increase once by passing this area. This range size depends on the web velocity and the task cycle time of the “MX_CrossCutter” functionblock. The range has to be at least 5deg (max. v web =400U/min, T cyc =2ms of the “MX- Crosscutter” functionblock ).With this set the following parameter: (Fig. 4-24) • P-0-0131 to S-0-0051 • The first element of P-0-0132 to 180deg. • The first element of P-0-0133 to 185deg DOK-MLD-S*-TechFB*****-AW01-EN-D
