Simultaneous Start - Mitsubishi Electric MELSEC iQ-R Series User Manual

Simultaneous Start

In a "simultaneous start", the positioning data set in "[Da.12] Start data No." and positioning data of other axes set in the
"condition data" are simultaneously executed (commands are output with the same timing). (The "condition data" is
designated with "[Da.14] Parameter".)
The control examples are shown when the "block start data" and "positioning data" are set as shown in the setting examples.
Setting examples
■Block start data setting example
Axis 1 block start data
1st point

It is assumed that the "axis 2 positioning data" for simultaneous starting is set in the "condition data" designated with "[Da.14]
Parameter".

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 the setting
examples and started.
1.
Check the axis operation status of axis 2 which is regarded as the simultaneous starting axis.
 Axis 2 is standing by  Go to the next 2.
 Axis 2 is carrying out positioning.  An error occurs and simultaneous start will not be carried out.
2.
Simultaneously start "positioning data No.1" for axis 1 and positioning data for axis 2 set in "condition data No.4".
Precautions
Positioning data No. executed by simultaneous starting axes is set to condition data ("[Da.18] Parameter 1", "[Da.19]
Parameter 2"), however, the setting value of the start axis (the axis which carries out positioning start) should be "0". If the
setting value is set to other than "0", the positioning data set in "[Da.18] Parameter 1", "[Da.19] Parameter 2" is given priority
to be executed rather than "[Da.12] Start data No.".
