摘要： A CPU unit of PLC executes a motion control and a sequence control. The CPU unit stores a control program for executing the motion control using a CAM table, and a first CAM table and a second CAM table. When a microprocessor receives a predetermined instruction during execution of the control program, the microprocessor switches the CAM table used in the execution of the control program from the first CAM table to the second CAM table. On the basis of the switching of the CAM table, the microprocessor outputs the execution results of the control program using the second CAM table to an apparatus to be controlled.

摘要： A method for controlling an automatically operated lathe, provided with at least one spindle and at least one tool rest, includes the following steps. First, each of a plurality of transfer position data required in a sequence of machining programs in connection with at least one spindle and at least one tool rest is provided in a form of a cam-reference data directing a transfer position as a function of a cam rotation quantity. A plurality of pulse-train generating sources, each of which generates any pulse train, is also provided. Next, with regard to each of the plural transfer position data, a pulse-train generating source for generating a pulse train defining the cam rotation quantity as one component of the cam-reference data is designated, with the pulse-train generating source being selected from the plural pulse-train generating sources. Then, each of the plural transfer position data provided in the form of the cam-reference data is processed by using the pulse train generated through the pulse-train generating source as designated, so as to control a relative feed motion between at least one spindle and at least one tool rest in the sequence of machining programs.

摘要： It is possible to easily change CAM tables, which are used for executing an electronic CAM operation. A CAM computation program performs an electronic CAM operation, using a CAM table that is an array in which displacements of a slave axis of an electronic CAM are associated with phases of a master axis of the electronic CAM. A CAM table generating program receives input of a CAM definition variable that defines an electronic CAM operation to be realized by a motion control, and generates a CAM table in which a CAM curve is stored as an array corresponding to the inputted CAM definition variable. A microprocessor performs a CAM computation program using the CAM table. If the microprocessor receives the input of the CAM definition variable, the microprocessor performs the CAM table generating program to generate the CAM table, and stores the generated CAM table into the main memory.

摘要： A path table operation is performed while updating the reference positions. When a read-out command in the path cycle table is read out, the reference positions are withdrawn and reset, and the respective axial positions at the time of the initiation of the path cycle command are stored. From the next period, the target positions are determined by adding the positions at the time of initiation to the respective axial positions corresponding to the reference positions stored in the path cycle table, and a path table operation is performed. A single path cycle table is sufficient for storing commands for portions to be repeatedly worked.
