PLC A method of independent control period allocation of axis in the PLC positioning system

摘要

The present invention relates to a method for allocating control periods of a PLC positioning system. Provided is a method for independently allocating a control period to each axis in a PLC positioning system, the method comprising: a step of allocating different control periods to each axis by dividing the axes into a first axis group having a first control period and a second axis group having a second control period for each axis; a step of performing a position control operation of the first axis group through task switching by an interrupt when the position control operation of the first axis group is requested during a position control operation of the second axis group; and a step of performing a position control operation of the second axis group through task switching by the interrupt after completing the position control operation of the first axis group.
