AXIS_REF_SM3* AXIS_REF_SM3
When Execute turns
to True and Busy is
False.
*Note: AXIS_REF_SM3(FB): Every function block contains this variable, which works as the starting program for function blocks.
 Function
 The input values of VelocityDiff, Distance, Acceleration, Deceleration and Jerk are superimposed on the on-going
motion of the previous instruction.
 If executing MC_MoveSuperImposed block in Standstill state, the function will be identical to MC_MoveRelative.
 MC_MoveSuperImposed can be aborted by other function blocks.
 An error will occur when MC_MoveSuperImposed is repeatedly run on the same axis.
 If changing the input values during the execution of MC_MoveSuperImposed or re-execute the function block before
the instruction finished, the axis will react according to the new superimposed values and instruction, which are the
sum of the previous instruction and MC_MoveSuperimposed instruction. When the superimposed distance is reached,
the axis will resume the operation of the previous instruction until the superimposed total distance is reached.
 MC_MoveSuperimposed and the function block, which is previously run, will be interrupted if a new function block has
started while MC_MoveSuperimposed is superimposed on other 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
 The example below describes the behavior of MC_MoveSuperImposed applied to MC_MoveVelocity.
