10HIGH-LEVEL POSITIONING CONTROL

10.3.3 Condition start

MELSEC-Q

In a "condition start", the "condition data" conditional judgment designated in "

Da.14

Parameter" is carried out for the positioning data set in "

Da.12

Start data No.". If the

conditions have been established, the " block start data" set in "1: condition start" is executed. If the conditions have not been established, that " block start data" will be ignored, and the "block start data" of the next point will be executed.

Section [2] shows a control example where the " block start data" and "positioning data" are set as shown in section [1].

[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.

<1> The conditional judgment set in "condition data No. 1" is carried out before execution of the axis 1 "positioning data No. 1".

Conditions established Execute positioning data No. 1, 2, and 3 Go to <2>.

Conditions not established Go to <2>.

<2> The conditional judgment set in "condition data No. 2" is carried out before execution of the axis 1 "positioning data No. 10".

Conditions established Execute positioning data No. 10, 11, and 12

Go to <3>.

Conditions not established Go to <3>.

<3> Execute axis 1 "positioning data No. 50" and stop the control. 10 - 10
