Repeated Start (For Condition) - Mitsubishi Electric RD77MS2 User Manual

Repeated start (FOR condition)

In a "repeated start (FOR condition)", the data between the "block start data" in which "5: FOR condition" is set in "[Da.13]
Special start instruction" and the "block start data" in which "6: NEXT start" is set in "[Da.13] Special start instruction" is
repeatedly executed until the establishment of the conditions set in the "condition data".
Conditional judgment is carried out as soon as switching to the point of "6: NEXT start" (before positioning of NEXT start
point).
(The "condition data" designation is set in "[Da.14] Parameter" of the "block start data" in which "5: FOR condition" is set in
"[Da.13] Special start instruction".)
The control examples are shown when the "block start data" and "positioning data" are set as shown in the setting examples.

examples and started.
1.
Execute the axis 1 "positioning data No.1, 2, 3, 10, and 11".
2.
Carry out the conditional judgment set in axis 1 "condition data No.5".
 Conditions not established  Execute "Positioning data No.50, 51". Go to the above 1.
 Conditions established  Execute "Positioning data No.50, 51" and complete the positioning.
