Function Block Definitions
You can also use motion control instructions in user-defined function block definitions.
Additional Information
Design efficiency is improved through program structuring, and program visibility is improved if
a process with multiple operations is treated as a single function block.
Master Control Regions
The area in a ladder diagram between the Master Control Start instruction (MC) and the Master Con-
trol End instruction (MCR) is the master control region.
MC
MCR
Master cont
rol region
If a motion control instruction is located in the master control region, and the MC input condition is
F
ALSE, the following will occur.
• Motion control instructions for which the input variable, Enable or Execute, is connected directly to
the left bus bar are executed with a FALSE value for the input value.
• Inline ST sections are executed normally.
• The values of the output parameters are updated as normal even when the Enable or Execute input
variables to the motion control instructions are FALSE.
Enable-type Motion Control Instructions
• Instructions located in master control regions are equivalent to the programming shown on the
right in the following figure.
• When G0 is TRUE, MC_Power is executed normally.
• When G0 is FALSE, MC_Power is executed as if the Enable input variable was FALSE.
