6.7 High-Speed Counter Function
6.7.1 Overview
High-speed counter is the specific function of SD20 series. It is convenient for user to set external
command processing mode and control servo system.
High-speed counter integrates the function of data capture, which is using external or internal trigger
signal to capture the position data of motion axis instantaneously, and store to data array for the use of the
follow-up motion control.
High-speed counter is applied mostly in full closed-loop, electronic cam, built-in PLC andpulse
command function. It is more convenient to process external data and more efficient to execute
instructions.
High-speed counter integrates 2 groups of counters, which can be set by user according to different
demands.
