Chapter 10 High-Level Positioning Control
10.5 Multiple axes simultaneous start control
The "multiple axes simultaneous start" starts outputting the command to the specified
simultaneous starting axis at the same timing as the started 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.
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) The error "Error before simultaneous start" (error code:501) will occur and all
simultaneous starting axes will not start if the simultaneous starting axis start
data No. is not set to the axis control data on the start axis or set outside the
setting range.
(2) The error "Error before simultaneous start" (error code:501) will occur and all
simultaneous starting axes will not start if either of the simultaneous starting
axes is BUSY.
(3) The error "Error before simultaneous start" (error code:501) will occur and all
simultaneous starting axes will not start if an error occurs during the analysis
of the positioning data on the simultaneous starting axes.
(4) No error or warning will occur if only the start axis is the simultaneous starting
axis.
(5) This function cannot be used with the sub function Section 13.7.7 "Pre-
reading start function".
