SmcWGetZCount

Function

The number of Z-phase counts when Z-phase count according to Origin return motion or the numbers of Z-phase counts when Z-phase count operates are acquired.

Format

Ret = SmcWGetZCount( Id , AxisNo , ZMoveCount )

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.

ZMoveCount [ C, C++: short * ] [ Python: ctypes.POINTER(ctypes.c_short) ]

Specify the address of the variable that stores a present number of Z-phase counts.

Return Value

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

0	Terminated normally
Non-zero	Terminated abnormally

Remarks

The value (number of Z counts) set with ZCount of SmcWSetOrgMode or ZMoveCount of SmcWSetZCountMotion is stored until Z-phase is detected.
Therefore, the acquisition value doesn't change when the number of Z counts is set by "1".
Moreover, when the limit and the operation stop function are executed while operating, the number of Z counts is stored.

This function can be executed even if the device is in operation.

Example

The number of Z-phase counts of axis number 1 is acquired.

C, C++

long Ret;

short ZMoveCount;

Ret = SmcWGetZCount( Id , 1, &ZMoveCount );

Python

Ret = ctypes.c_long()

ZMoveCount = ctypes.c_short()

Ret.value = csmc.SmcWGetZCount( Id , 1, ctypes.byref(ZMoveCount) )
