Multiple axes simultaneous start
In this starting mode, the simultaneous starting axis and the started axis start outputting pulses at the same timing. Up to four
axes can be started simultaneously.
Control details
Perform the multiple axes simultaneous start by setting the following buffer memory areas and turning on a start trigger.
• Set a start data No. of each simultaneous starting axis (positioning data No. of each axis started simultaneously) 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.).
• Set 9004 to [Cd.3] Positioning start No. for the starting axis.
Ex.
The following figure shows the control when the multiple axes simultaneous start control is performed with the axis 1 (starting
axis), axis 2, and axis 3.
Restrictions
• If [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.) of the started axis are not set, or the set values are outside the setting range, Error before
simultaneous start (Error code: 1991H) occurs and all the simultaneous starting axes will not start.
• If any of the simultaneous starting axes is in the axis BUSY state, Error before simultaneous start (Error code: 1990H)
occurs and all the simultaneous starting axes will not start.
• If an error occurs during the analysis of the positioning data on the simultaneous starting axes, Simultaneous start not
possible (Error code: 199EH) occurs and all the simultaneous starting axes will not start.
• If the simultaneous starting axis is the started axis only, no error or warning occurs.
