This “position error monitoring function” is effective in case that you judge convergence of position error at
creating Learning data or in case that you judge easily work precision at mass production
“Position error monitoring function“ is the following.
Command
Pos. error
Learning flag
Error monitoring
flag
(Note 1) If even position error once exceeds the threshold level during monitoring flag is 1, “range over flag”
does a latch to 1. Servo software does not clear this flag until next Learning flag becomes from 0 to 1.
(Note 2) “Range over flag” is output to outer signal F321. The bit position of F321 means NC axis number.
(Note 3) You should tune both “monitoring start time” and “monitoring finish time” within the range that is not
influence in cutting precision to avoid becoming range over in case of excess reply in the movement
beginning or stop.
