4 PARAMETERS FOR POSITIONING CONTROL

4.2.4 Command in-position range

The command in-position is the difference between the positioning address (command position) and feed current value.

Once the value for the command in-position has been set, the command in-position signal (M2403+20n) turns on when the difference between the command position and the feed current value enters the set range [(command position - feed current value) (command in-position range)].

The command in-position range check is executed continuously during position control.
