⋅ During a threading cycle for turning
This signal goes low when:
⋅ Not in the threading mode or during a threading cycle
(d) Constant surface seed signal (CSS [#1, #2])
[Classification]
Output signal
[Function] This signal informs that constant surface speed control is being exercised.
[Output Condition]
This signal goes high when:
⋅ The constant surface speed control mode (G96) is set
This signal goes low when:
⋅ The constant surface speed control mode (G96) is not set
(e) Inch input signal (INCH)
[Classification]
Output signal
[Function] This signal informs that the inch input mode is set.
[Output Condition]
This signal goes high:
⋅ In the inch input mode (G20)
This signal goes low:
⋅ In the metric input mode (G21)
NOTE When the input mode is changed by setting data on the MDI panel, the state of this signal
changes accordingly.
2.3.39 Axis movement status output signals
(a) Position signals (INP1, INP2, INP3, ...)
[Classification]
Output signals
[Function] A position signal informs that the corresponding controlled axis is in the effective area.
A position signal is provided for each controlled axis; a number appended to a signal name
represents a controlled axis number.
INP 1
1 ……The tool is in the effective area for the first axis.
2 ……The tool is in the effective area for the second axis.
3 ……The tool is in the effective area for the third axis.

[Output Condition]
A position signal goes high when:
⋅ The corresponding controlled axis has no acceleration/deceleration delay and has a ser-
vo error within a certain range
A position signal goes low when:
⋅ The corresponding controlled axis has a nonzero acceleration/deceleration delay
⋅ The corresponding controlled axis has a servo error exceeding a certain range
NOTE 1 In a very slow feed operation, these signals may go high during movement.
NOTE 2 A parameter can remove from the conditions for driving these signals high the requirement that
the servo error must be within a certain range. In this case, these signals are turned on and
off, only depending on whether the acceleration/deceleration delay is zero.
