Changing Input Variables during Execution of Motion Control In-
structions (Restarting Instructions)
If the values of the input variables to an instruction instance are changed while the motion control in-
struction is under execution and then Execute is changed to TRUE again, operation will follow the new
values.
For details on re-execution of MC Function Module instructions, refer to the NY
-series Industrial Panel
PC / Industrial Box PC Motion Control User’s Manual (Cat. No. W559).
Multi-execution of Instructions with Buf
ferMode
A different instruction instance can be executed during axis motion.
Y
ou can specify when a motion starts by setting an input variable called BufferMode.
The following Buffer Modes are supported for BufferMode.
• Aborting
: Abort (Aborting)
• Buf
fered
: Standby (Buffered)
• Blending Low
: Blending with the low velocity (BlendingLow)
• Blending Previous
: Blending with the previous velocity (BlendingPrevious)
• Blending Next
: Blending with the next velocity (BlendingNext)
• Blending High
: Blending with the high velocity (BlendingHigh)
In Aborting
mode, other motions are aborted and the function block is executed immediately.
In other buffer modes, the next instruction waits until an output variable such as Done or InVelocity
from the currently executed instruction changes to TRUE.
For Buffered mode, the next instruction is executed after the current instruction is executed and Done
changes to TRUE.
For the Blending modes, two instruction motions are executed consecutively without pausing. The
transition velocity between the two motions is selected from four buffer modes.
For the MC Function Module, BufferMode is also referred to as multi-execution of instructions.
For details on multi-execution of instructions for the MC Function Module, refer to the NY-series
Industrial Panel PC / Industrial Box PC Motion Control User’s Manual (Cat. No. W559).
Whether multi-execution of instructions is supported in the MC Function Module depends on the cur-
rent axis status, the current axes group status, and the instruction to execute. Refer to A-1 Instructions
for Which Multi-execution Is Supported on page A-2 for detailed information.
