These motion control instructions are executed when the input variable Execute to the
instruction changes to TRUE. These instructions will continue execution until one of the
following status occurs.
• The specified operation is completed.
• Another motion control instruction is executed and interrupts operation.
• The instruction is restarted when Execute changes from FALSE to TRUE again.
Values for the other input variables are input when Execute changes to TRUE.
These motion control instructions are executed every period while the input variable
Enable to the motion control instruction is TRUE. As long as Enable is TRUE, the other
input variables are also input every period. However, MC_MoveJog input variables
Velocity, Acceleration, and Deceleration are an exception to this rule. The values when
PositiveEnable or NegativeEnable changes to TRUE are used for these input variables.
