AXIS_REF_SM3* AXIS_REF_SM3
When Execute is rising edge triggered
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
 When Execute changes to True, the homing operation starts to be performed on the axis specified in Axis.
 Position is to specify the set position for homing.
 In case the MC_Home command is interrupted by MC_Stop and
xWaitForHaltWhenStopInterruptsHome is TRUE, MC_Stop has to wait till the driver reaches velocity zero before
setting to Done. Instead, if xWaitForHaltWhenStopInterruptsHome is FALSE, Done will shift to true once MC_Stop
interrupts MC_Home.
 When the MC_Home is running, after power off, the Home function block status will change to Error. For SoftMotion
V4.10.0.0 and later, when the MC_Home is running, after power off, the Home function block status will change to
Abort.
 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
 Example 1: Explain how to perform homing by using MC_Home and setting homing mode on the parameter
configuration page with DIAdesigner-AX.
