4. REFERENCE POSITION ESTABLISHMENT
363
NOTE
When reference position return is selected, an axis whose
reference position return end signal is already “1” or an axis
whose reference position return end signal was set “1” upon
completion of reference position return is locked, and
movement along that axis is disabled while the reference
position return selection signal (ZRN) is “1”. To perform
movement along such an axis, ZRN must be set “0”, and the
feed axis and direction selection signal must be set “0” then
set “1” again.
[Classification] Input signal
[Function] These signals decelerate the feedrate for manual reference position return
so that the reference position is approached at a low feedrate.
The deceleration signals are provided for axes in a one--to--one correspon-
dence. A number appended to a deceleration signal represents a con-
trolled axis number.
1 : Reference position return deceleration signal for the first axis
2 : Reference position return deceleration signal for the second axis
3 : Reference position return deceleration signal for the third axis

[Operation] For the operation of the control unit in response to the deceleration signal,
see the description of the basic procedure for manual reference position
return.
[Classification] Output signal
[Function] These signals report that the tool is at the refernce position on a controlled
axis.
These siganls are provided for axes in a one--to--one corespondence.
A number appended to a signal represents a controlled axis number.
1 : Reference position return end signal for the first axis
2 : Reference position return end signal for the second axis
3 : Reference position return end signal for the third axis
