Servo Parameters
After setting the servo parameters at a peripheral device, execute a "RELATIVE CHECK" and
execute positioning control in the "NO ERROR" status. If there is an error, check the relevant
points indicated in this manual and reset it.
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) will come 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 positioning
control.
