In a motion task, two or more multiple execution commands can be execut-
ed simultaneously in one Unit Cycle. A command of this type can be exe-
cuted along with a single execution command or other multiple execution
commands. Commands related to operations (arithmetic, logic, etc.) are
usually of this type.
In the respective tables in this section, the word 'SINGLE' is used to indicate
the [Single execution command], and 'MULTI' to indicate the [Multiple execu-
tion command].
Refer to the 6-2-1 Command List (page 286) for the type of each command.
4. Multiple execution commands are executed under the following conditions:
• When there are no commands being executed.
• When a single execution command, which has a lower block number than
that of the multiple execution command, is being executed. (A multiple
execution command is not executed before any earlier single command
not executed yet.)
In the stop mode, the motion program advances following the 'Basic Concept'
in the previous page.
Nevertheless, in the 'Single Block Operation Mode', regardless of SINGLE/
MULTI, one block is executed at a time.
Operation image:
It takes three cycles to execute one single execution command and the maxi-
mum number of simultaneous executions is set to four. No parallel branching.
