10HIGH-LEVEL POSITIONING CONTROL

10.3.5 Simultaneous start

MELSEC-Q

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

(pulses are output with the same timing). (The "condition data" is designated with "

Da.14

Parameter".)

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

It is assumed that the "axis 2 positioning data" for simultaneous starting is set in the

"condition data" designated with "

Da.14

Parameter".

[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> Simultaneously start the axis 1 "positioning data No. 1" and axis 2 positioning data set in "condition data No. 4". After the execution of axis 1 "positioning data No. 1, 2, and 3" is completed, go to <2>.

<2> Simultaneously start the axis 1 "positioning data No. 10" and axis 2 positioning data set in "condition data No. 5".

Standing by after completion of axis 2 positioning data simultaneously started in <1>. Go to <3>.

Executing axis 2 positioning data simultaneously started in <1>. "Error".

<3> Simultaneously start the axis 1 "positioning data No. 50" and the axis 2 positioning data set in "condition data No. 6" after the completion of the execution of axis 1 "positioning data No. 10, 11, and 12".

Standing by after completion of axis 2 positioning data simultaneously started in <2>. Go to <4>.

Executing axis 2 positioning data simultaneously started in <2>. "Error".

<4> After the execution of the axis 1 "positioning data No. 50" is completed, stop the control.
