Chapter 10 High-Level Positioning Control
10.5 Multiple axes simultaneous start control
The "multiple axes simultaneous start control" starts and controls the multiple axes
simultaneously by outputting command to the axis to be started at the same timing as
the start axis.
The maximum of four axes can be started simultaneously.
[1] Control details
The multiple axes simultaneous start control is carried out by setting the
simultaneous start setting data to the multiple axes simultaneous start control
buffer memory of the axis control data, and the "9004" to "
Cd.3
Positioning start
No.
" of the start axis, and then turning ON the positioning start signal.
• QD77MS2 ...........Set the start data No. of simultaneous starting axis
(positioning data No. to be started simultaneously for each
axis) in "
Cd.30
Simultaneous starting axis start data No. (axis 1
start data No.)"
and "
Cd.31
Simultaneous starting axis start data
No. (axis 2 start data No.)
".
• QD77MS4 ...........Set the start data No. of simultaneous starting axis
(positioning data No. to be started simultaneously for each
axis) in "
Cd.30
Simultaneous starting axis start data No. (axis 1
start data No.)"
to "
Cd.33
Simultaneous starting axis start data No.
(axis 4 start data No.)
".
• QD77MS16 .........Set the number of axes to be started simultaneously and axis
No. in "
Cd.43
Simultaneous starting axis
", and the start data No.
of simultaneous starting axis (positioning data No. to be
started simultaneously for each axis) in "
Cd.30
Simultaneous
starting own axis start data No.
" and "
Cd.31
Simultaneous starting
axis start data No.1
" to "
Cd.33
Simultaneous starting axis start data
No.3
".
[2] Restrictions
(1) An error will occur and all simultaneously started axes will not start (error
code: 501) if the simultaneously started axis start data No. is not set to the
axis control data on the start axis or set outside the setting range.
(2) An error will occur and all simultaneously started axes will not start (error
code: 501) if either of the simultaneously started axes is BUSY.
(3) An error will occur and all simultaneously started axes will not start (error
code: 501) if an error occurs during the analysis of the positioning data on the
simultaneously started axes.
(4) No error or warning will occur if only the start axis is the simultaneously
started axis.
(5) This function cannot be used with the sub function Section 13.7.7 "Pre-
reading start function".
