Name Function
Specify the
Axis
axis.
*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.

Data Type
AXIS_REF_SM3*
Setting Value
AXIS_REF_SM3 When bEnable is True and bBusy is False.
