MANUAL RANDOM FEED
—
1ST AXIS NO.
[Function]
This signal specifies a number of the axis component to move in manual random feed mode.
Components of up to three axes can be moved simultaneously in manual random feed mode. This
signal is used to specify one of them.
[Operation]
(1) The "Manual random feed 1st axis number" (CX11~CX116) must be set before strobe signal
CXS8 is turned ON. An attempt to set it during motion shall fail.
(2) Besides this signal (CX11~CX116), there are two signals, "Manual random feed 2nd axis
number" (CX21~CX216) and "Manual random feed 3rd axis number" (CX31~CX316). The axis
numbers need not be specified in ascending order.
(3) The "Manual random feed 1st axis number" is validated by turning ON the "Manual random feed
1st axis valid (CX1S)" signal explained later. Similarly, the validity signals (CX2S and CX3S) are
also provided for the 2nd and 3rd axis number signals.
(4) Axis numbers can be specified as follows:
Signal

specification
1st axis
2nd axis
3rd axis
4th axis
(5) Motion of the specified axis component is as follows:
(a) The motion of the axis component specified by the "Manual random feed 1st axis number"
signal corresponds to the contents of manual random feed 1st axis movement data (R914
and R915).
(b) The motion of the axis component specified by the "Manual random feed 2nd axis number"
signal corresponds to the contents of manual random feed 2nd axis movement data (R916
and R917).
(c) The motion of the axis component specified by the "Manual random feed 3rd axis number"
signal corresponds to the contents of manual random feed 3rd axis movement data (R918
and R919).
