[Classification] Input signal
[Function] These signals decelerate the feedrate for manual reference position return
to a low feedrate (FL).
Deceleration signals are provided for each axis. The number appended
to a deceleration signal represents a controlled 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
:
:
*DEC 1
[Operation] For a description of the control unit response to the deceleration signal,
see 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 each axis.
The 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
:
:
ZP 1
[Output condition] These signals are set to “1” when:
D Manual reference position returns is completed, and the axis position
is in the in–position area.
D Automatic reference position return (G28) is completed, and the axis
position is in the in–position area.
D Reference position return check (G27) is completed, and the axis
position is in the in–position area.
These signals turn to “0”when:
D The tool has moved from the reference position.
D An emergency stop is applied.
D A servo alarm is raised.
