SmcWGetMoveSpeed

Function

Retrieves the pulse out speed under operation.

Format

Ret = SmcWGetMoveSpeed( Id , AxisNo , MoveSpeed )

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.

MoveSpeed [ C, C++: double * ] [ Python: ctypes.POINTER(ctypes.c_double) ]

Specify the address of the variable that stores the pulse out speed under operation.

Return Value

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

0	Terminated normally
Non-zero	Terminated abnormally

Remarks

The speed below the decimal point cannot be acquired in this function.
It is dropped below the decimal point.
And, there may be a inaccuracy between the retrieved speed and the actual speed of the motor.
This is because the error of drive internal calculation. Please note that.

When the interpolation operates, only the interpolation control axis's speed can be retrieved by this function.
This is the specification for LSI.

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

Example

The pulse out speed of axis number 1 is acquired.

C, C++

long Ret;

double MoveSpeed ;

Ret = SmcWGetMoveSpeed( Id , 1, &MoveSpeed );

Python

Ret = ctypes.c_long()

MoveSpeed = ctypes.c_double()

Ret.value = csmc.SmcWGetMoveSpeed( Id , 1, ctypes.byref(MoveSpeed) )
