Case1 Case2 Case3
Case 1： When JogForward or JogBackward changes from FALSE to TRUE, Busy changes to TRUE.
When the jogging stops, the velocity of the axis is decreased to 0, Done changes to TRUE and
Busy changes to FALSE.
Case 2： When JogForward or JogBackward changes from FALSE to TRUE, CommandAborted changes
to TRUE and meanwhile, Busy changes to FALSE after the instruction is aborted by other motion
instruction. CommandAborted changes to FALSE when JogForward or JogBackward changes
from TRUE to FALSE.
Case 3： After JogForward or JogBackward changes from FALSE to TRUE, Error will change to TRUE
and ErrorID will show corresponding error codes if any error occurs such as axis alarm or Offline.
Meanwhile, Busy will change to FALSE. Error will change to FALSE and the value of ErrorID will
be cleared to 0 when JogForward or JogBackward changes from TRUE to FALSE.
Function
DMC_Jog jogs an axis. The JogForward parameter controls the axis to run forward and the
JogBackward parameter controls the axis to run backward. When the jogging stops, Done changes to
TRUE and one cycle later, it changes to FALSE. Meawhile, Busy changes to FALSE.
