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 pulses 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
Multiple axes simultaneous start control is executed as follows.
Set the start data No. to the buffer memory areas "
Cd.30
to
Cd.33
Simultaneous starting axis start data No. (axis 1 to 4 start data No.)".
Set "9004" to "
Cd.3
Positioning start No." of the start axis.
Turn ON the positioning start signal.
[2] Restrictions
(1) The error "Error before simultaneous start" (error code: 501) will occur and all
simultaneously started axes will not start 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) The error "Error before simultaneous start" (error code: 501) will occur and all
simultaneously started axes will not start if either of the simultaneously started
axes is BUSY.
(3) The error "Error before simultaneous start" (error code: 501) will occur and all
simultaneously started axes will not start 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 12.7.7 "Pre-
reading start function".
[3] Multiple axes simultaneous start control procedure
The procedure for multiple axes simultaneous start control is as follows.
3)
1)
2)
Set " Cd.30 to Cd.33 Simultaneous starting
axis start data No.".
Write [9004] to " Cd.3 Positioning start No.".
Turn ON the positioning start signal to be started.
