[2] 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 section [1] and started.
point of axis 1 is set as shown in section [1] and started.
<1> Carry out the conditional judgment set in "condition data No. 5" for the axis 1
"positioning data No. 1".
Conditions not established Go to <2>.
Conditions established Go to <3>.
Conditions established Go to <3>.
<2> Execute axis 1 "positioning data No. 1, 2, 3, 10, 11, 50, and 51", then go to
<1>.
<3> Execute axis 1 "positioning data No. 1, 2, 3, 10, 11, 50, and 51", then stop
the control.
