1 : 1st axis is removed
2 : 2nd axis is removed
:
14 :14th axis is removed
[Operation]
When control axis removal signal (DTCHn) turns ON, the corresponding axis is exempted from
control.
(1) Specified axis is not under any positioning control.
(2) "Servo alarm", "Stroke end alarm" and other alarms are not applied to specified axis.
(3) Interlock signal applied to specified axis is deemed to be ON.
