SmcWSyncMotionStart

Function

The operation of the axis of the synchronous start waiting state for a synchronous control begins.

Format

Ret = SmcWSyncMotionStart( Id, AxisNo )

Parameters

Id [ C, C++: short ] [ Python: ctypes.c_short ]

Specify the device ID retrieved by SmcWInit function.

AxisNo [ C, C++: short ] [ Python: ctypes.c_short ]

Specify axis number.

Return Value

Ret [ C, C++: long ] [ Python: ctypes.c_long ]

Remarks

It becomes a synchronous start waiting state by executing the SmcWMotionStart  for the axis for the same period control after the SmcWSetSync is executed.
It doesn't become a synchronous start waiting state only by executing the SmcWSetSync.
If the SmcWGetPulseStatus is executed by the synchronous start waiting state, it becomes PulseSts=3 (synchronous start waiting).

Please execute the SmcWMotionStop to release the synchronous start waiting state.
Moreover, the synchronous start waiting state is released as for the axis besides the synchronous start waiting state when releasing it.
Operation doesn't begin even if this function is executed as for the released axis.

Either of axis that synchronizes stops and other axes stop when coming in contact or stopping Limit.
Therefore, when the starting point resume operation by synchronization is done by this function, it is necessary to note the record operation further.

When you do the starting point resume operation synchronously two axes:

If the other axis is not completed according to timing that one of axes completed the starting point return, the axis not completed continues the starting point resume operation as it is.
Therefore, when the starting point returns by the device done to operate by two axes, it is necessary to arrange the position of the starting point sensor.
