4. Motion Control Instructions 4.7.10. Flying Shear Instructions 4.7.10.1. APF_FlyingShear_Init Explanation of the instruction: The instruction is used for initializing the radius of master axis and slave axis, the cutting length, synchronous area and etc if the flying shear relation has not been established. After execution of the instruction is completed, the relevant parameters are loaded so as to be called while the flying shear relation is being established. If the flying shear relation has been established, the instruction is used for modifying the flying shear parameters.
And the newly set parameters will be effective in the following cycle after the execution of the instruction is finished. Explanation of input and output parameter of the instruction: DVP-MC operating manual 4-175 API APF FlyingShear Init _ _ Initialize flying shear Controller 223 10MC11T Parameter Data Available Explanation name type device Execute When “Execute” turns off -> on, the instruction is executed. BOOL M,I,Q, constant MasterRadius The radius of master axis, i.e. the radius of the feed roller REAL Constant, D SlaveRaduis The radius of slave axis, i.e. the radius of the corresponding roller of slave axis.
By adopting the lead screw, R2= Lead of the lead screw / 2π REAL Constant, D CutLength The cutting length of material REAL Constant, D MasterStartPosition The start position of master axis. When master axis reaches this position, slave axis will chase the master axis starting from the wait position to realize the synchronous speed. REAL Constant, D
