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.

Claims2

Dependent claims

A method of reducing execution time for a position command in a position servo system, comprising the steps of:

(a) transmitting a position command from a main controller to a position servo at a first predetermined time interval;
(b) interpolating a part of said transmitted position command at a second predetermined time interval which is less than said first time interval;
(c) executing said interpolated position command;
(d) pausing said position servo so as to pause position command execution for a predetermined period of time;
(e) calculating a non-executed part of said position command to provide a calculated position command and buffering said calculated position command in said position servo, during said predetermined pause time period;
and
(f) executing said non-executed part of the position command, after said predetermined pause time period.
