[Classification] Input signal
[Function] These signals are also used by the CNC. The signals are provided for each
direction of the individual controlled axes. The plus or minus sign in the
signal name indicates the direction, and the number at the end corresponds
to the axis number of the controlled axis.
"EDx
1 … Feed along the first axis is decelerated.
:
4 …Feed along the fourth axis is decelerated.
+ … Feed in the positive direction is decelerated.
:
– … Feed in the negative direction is decelerated.
When any of the following axis control command is specified while the
EDC bit (bit 0 of parameter 8005) is held at 1, the external deceleration
function becomes effective:
(1)Rapid traverse (EC0g to EC6g: 00h)
(2)Cutting feed per minute (EC0g to EC6g: 01h)
(3)Reference position return (EC0g to EC6g: 05h)
(4)Continuous feed (EC0g to EC6g: 06h)
(5)First reference position return (EC0g to EC6g: 07h)
(6)Second reference position return (EC0g to EC6g: 08h)
(7)Third reference position return (EC0g to EC6g: 09h)
(8)Fourth reference position return (EC0g to EC6g: 0Ah)
(9)Machine coordinate system selection (EC0g to EC6g: 20h)
While the signal is held at “0”, the feedrate in the corresponding direction
of axial movement can be reduced to the speed specified in parameter
1427 (external deceleration speed).
When the feedrate is lower than the external deceleration speed, the
specified feedrate is valid.
The feedrate on other axes for which the signal is not held at “0” is not
affected.
