ABSTRACT:
A method of reducing execution time for a position command in a position servo system is described in which a position command is transmitted from a main controller to the position servo at a first predetermined time interval and the position servo interpolates and executes a first part of the transmitted position command at a second predetermined time interval which is less than the first predetermined time interval. Execution of the position command is paused for a predetermined period of time during which a non-executed part of the position command is calculated and stored into the position servo buffer. After the predetermined pause time, the non-executed part of the position command is executed.
