4 HIGH-LEVEL POSITIONING CONTROL
4.3 Setting the Block Start Data
Simultaneous start
In a "simultaneous start", the positioning data set in the "[Da.12] Start data No." and positioning data of other axes set in the
"condition data" are simultaneously executed (commands are output with the same timing). (The "condition data" is
designated with "[Da.14] Parameter".)
The control examples are shown when the "block start data" and "positioning data" are set as shown in the setting examples.
Setting examples
■Block start data setting example
It is assumed that the "axis 2 positioning data" for simultaneous starting is set in the "condition data" designated with "[Da.14]
Parameter".
■Positioning data setting example
Control examples
The following shows the control executed when the "block start data" of the 1st point of axis 1 is set as shown in the setting
examples and started.
1. Check the axis operation status of axis 2 which is regarded as the simultaneously started axis.
Axis 2 is standing by Go to the next 2.
Axis 2 is carrying out positioning. An error occurs and simultaneous start will not be carried out.
2. Simultaneously start the axis 1 "positioning data No. 1" and axis 2 positioning data set in "condition data No. 4.
Precautions
Positioning data No. executed by simultaneously started axes is set to condition data ("[Da.18] Parameter 1", "[Da.19]
Parameter 2"), but the setting value of start axis (the axis which carries out positioning start) should be "0". If the setting value
is set to other than "0", the positioning data set in "[Da.18] Parameter 1", "[Da.19] Parameter 2" is given priority to be executed
rather than "[Da.12] Start data No.".
