Repeated Start (For Condition) - Mitsubishi Electric AJ65BT-D75P2-S3 User Manual

10 ADVANCED POSITIONING CONTROL

10.3.8 Repeated start (FOR condition)

In a "repeated start (FOR condition)", the data between the "start block data" in which
"6: FOR condition" is set in " Da.12 Special start command" and the "start block data"
in which "7: NEXT start" is set in " Da.12 Special start command" is repeatedly
executed until the establishment of the conditions set in the "condition data".
The condition is evaluated at the time of change to the point of "7: NEXT start" (just
before the positioning control for the point of NEXT start).
(The "condition data" designation is set in " Da.13 Parameter" of the "start block data"
in which "6: FOR condition" is set in " Da.12 Special start command".)
Section (2) shows a control example where the "start block data" and "positioning data"
are set as shown in section (1).

(2) Control examples
The following shows the control executed when the "start block data" of the 1st
point of axis 1 is set as shown in section (1) and started.
<1> Perform the processing of "positioning data No. 1, 2, 3, 10, and 11" of the
axis 1.
<2> Evaluate the condition set in "condition data No. 5" of the axis 1.
Conditions not established
