• If the velocity override factor is set to 0, the target velocity will be 0. Axis operation will decelerate to
a velocity of 0, and operation will continue.
If you want to pause the axis motion while maintaining the operation status, set the override factor to
0.
Status.Discrete and Status.Continuous in the Axis V
ariable do not change at this time.
• The override factors are always updated when the instruction is executed as long as Enable re-
mains TRUE.
• The override factors apply to operation commands for new target velocities, e.g., when you start a
stopped axis, re-execute a motion instruction, or perform multi-execution of motion control instruc-
tions.
• The override factors will return to 100% when Enable changes to FALSE.
• If an axis error occurs during MC_SetOverride instruction execution, the value of Enabled for the
MC_SetOverride instruction remains TRUE.
Precautions for Correct Use
When Enable
to this instruction changes to FALSE, Enabled and Busy from this instruction
change to FALSE.
The axis will accelerate or decelerate to a velocity with a 100% override factor.
Additional Information
Influence on Other Instructions
Use this instruction to temporarily change the target velocities of other instructions.
This instruction has no ef
fect on instructions to which a target velocity is not input or instructions
for which the target velocity is updated every period, such the Cyclic Synchronous Velocity Con-
trol instruction.
However, Enabled remains TRUE even if the MC_SetOverride (Set Override Factors) instruc-
tion is executed for an instruction to which it does not apply.
