Timing for Shifting to True 
Timing for Shifting to False 
ConstantVelocity 
 
When the axis moves at a constant 
speed. 
 
When the axis moves at a non-constant 
speed. 
  When the axis moves with acceleration. 
 
When the axis moves without acceleration. 
 
When the axis moves with deceleration.

When Enable turns to True. 
*Note: AXIS_REF_SM3(FB): Every function block contains this variable, which works as the starting program for function blocks. 
 
  Troubleshooting 
 
  If an error occurs during the execution of the instruction, Error will change to True. You can refer to ErrorID (Error Code) 
to address the problem. 
 
  Example 
 
  This example demonstrates using MC_ReadStatus to read axis status while executing MC_MoveAbsolute.
