Reference position return deceleration signals *DEC1 to *DEC8<X009>
[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.

[Operation] For a description of the control unit response to the deceleration signal,
see the basic procedure for manual reference position return.
Bit 0 (GDC) of parameter No. 3006 can be set to 1 to use input signal
G196.
NOTE
Bit 2 (XSG) of parameter No. 3008 can be set to
specify whether to fix the address of the reference
position return deceleration signals to X009 or use a
desired X address.
When bit 2 (XSG) of parameter No. 3008 is set to 1,
the X address and bit position for each reference
position return deceleration signal are determined
according to the setting of parameters Nos. 3013
and 3014.
Bit 5 (DEC) of parameter No. 3003 can be set to set the logic for the
deceleration signals (*DEC1 to *DEC8).
Reference position return end signals ZP1 to ZP8<Fn094>
[Classification] Output signal
[Function] These signals report that the tool is at the reference position on a
controlled axis.
These signals are provided for each axis. The number appended to a
signal represents a controlled axis number.

[Output condition] These signals are set to "1" when:
- Manual reference position returns is completed, and the axis
position is in the in-position area.
- Automatic reference position return (G28) is completed, and the
axis position is in the in-position area.
- Reference position return check (G27) is completed, and the axis
position is in the in-position area.
