AXIS_REF_SM3* AXIS_REF_SM3 When bEnable is True and bBusy is False.
*Note: AXIS_REF_SM3 (FB): All function blocks contain this variable, which works as the starting program for function blocks.
 Function
 DMC_ReadMotionState reads the behavior state of the axis in motion (i.e. acceleration/deceleration, constant velocity,
positive/negative direction of motion).
 When the velocity is 0, the output bConstantVelocity changes to True.
 Troubleshooting
 When an error occurs during the execution of the instruction, bError will change to True. Refer to ErrorID (Error
Code) to address the problem.
 Programming Example
 The example shows the motion behavior that MC_ReadMotionState reads MC_MoveVelocity and MC_Stop.
